Canon PowerShot S90 10MP Digital Camera with 3.8X Wide Angle Optical Image Stabilized Zoom and 3-Inch LCD (Old Model)

I'm a very amateur camera user. I understand the basic terms and settings (ISO, aperture, shutter speed, image stabilization, exposure) but I am impatient and like to get things set and just use the camera. I bought this camera because I wanted the ability to use the camera indoors in low light without a flash. Due to the relatively high price, my expectations were high. My cam was delivered just last week, and having used it at an event in a local bar the best word I can use to describe this camera is "magic". This camera takes in so much light it really seems like magic. The event I was documenting was in a very dimly lit room. The only lighting sources in the room were incandescent chandeliers dimmed as low as they would go. I set my iso to 1000 in aperture priority mode, f2.0 (this level is only available in the widest zoom), adjusted white balance for incandescent, and took some shots. Most of the shots used 1/6-second shutter speed, which was just fine due to the image stabilized lens. The IS performance is improved over my last Canon compact. I don't have steady hands, and I like to take quick sloppy shots. If the IS in this cam can handle my hands, a very-careful steady shooter could probably get away with 1/4 second. The resulting images were so bright and had such great color everyone that saw them was in awe. The resulting images appeared more bright and colorful than with a naked eye. Shooting with such high ISOs is like having night vision built into the camera. Noise levels were low enough and color was so good that I can easily print very nice 5x7s from this night. I took a few candid shots of people in motion at the bar, so I had to bump the ISO to 1600 to get a faster shutter speed (at ISO 1600 I got about 1/30sec in the dimly lit bar). At ISO 1600, color is still acceptable and very nice 4x6 prints, web postings, and email will be no problem. ISO 1600 on this cam is comparable to what most compact cams produce at ISO 400. I've never seen a compact cam take such great shots using high-ish ISO settings. I am just as happy with the results as when using my EOS 20D digital SLR. A critical professional may argue that this cam isn't as great as an SLR, but for normal-sized prints and digital sharing, this camera makes images that are as good as a consumer SLR. My last compact was a Canon SD800is. I love that camera, but images are mostly unusable above ISO400, due to muted color, and grain. The S90 goes two full ISO stops beyond what can be done with a typical $300 compact camera. Combine high-ISO performance with the f2.0 option and you can take great shots in 1/3 of the light required for most $300 compact cams. Adjusting camera settings is a dream. I am just as in control as I am with my EOS 20D SLR. I've used friends' canon rebel SLRs, and the controls on this compact are even better than them. Between the front ring, rear dial, and shortcut button, you have instant control of three camera functions without even really looking. All of the controls are customizable. If you've ever used other canon cameras in the past, you won't really even need to use the excellent printed manual (yes! a printed manual!). I've not taken enough shots with it to test whether the battery can actually deliver 200 from a charge, but 200 isn't really great battery performance and I bought a backup battery from an Amazon marketplace seller for longer outings (under $30 shipped). I also highly recommend the Canon compact leather case. This camera easily fits in any pocket, but I'm pretty sure that pocket lint and dust is what did in my last compact camera. The Canon compact leather case for the S90 mounts on your belt and offers light protection away from keys and pocket lint. The body is comparable in size to Canon elphs. My SD800 elph is 1/2in shorter, but the height and thickness is identical (not counting the lens ring, which makes the overall thickness of the S90 slightly thicker). I posted comparison pics between the SD800 and the S90 in the gallery. The rear display is really sharp and is viewable outdoors. I haven't bought a new camera in over three years and the display blew me away compared to my other cameras. I really can't compare the display to newer cams. Simply judging by the way it feels in the hand, the build quality is just average. The only real performance weakness is continuous shooting. Continuous shooting is really really slow. If you want a compact and think you'll ever want to photograph dimly lit subjects without a flash, this is THE camera to own. The price is 40% higher, but it takes in 300% more light. Unless you're shooting a lot of action, this cam is probably a better choice for people considering consumer-level SLRs like the Canon rebel line. I can't imagine anyone regretting buying this camera. It beats other compact pocket sized cameras by a wide margin.

As Chase Jarvis says........"The best camera is the one that's with you." So it goes with this little camera. Little in size but pretty big in features and picture quality. I also invested in the belt loop Canon leather carrying case and I have this camera with me wherever I go. So far (I've had it a few months) it's doing an excellent job. I shoot in raw (larger file size) and process in Lightroom 2 but it will certainly shoot in jpeg also. The quality is really good (even cranked up to ISO 800). It shoots well in low light. It doesn't have any extreme zoom to it but it's sufficient for most any need. I find that as small as it is, in my shaky hands, I couldn't steady it very well if it zoomed any more than it already does. I have also invested in a monopod for it and that really helps with steadying it. It does have the anti shake feature that most cameras have, but I'm pretty shaky and needed a little more (or else I have to adjust up the shutter speed). Not to mention that it's handy to be able to hold the monopod out in front of me and take my wife's and my picture in whatever setting we happen to be in (I put a small ballhead on the monopod) so I could adjust the camera to whatever angle I needed to get our self portrait shots. That's pretty nice!! Just set the timer and smile!!! The features are nice, it's picture quality is great, and it truly gives you total control if you want it (Manual). For those that don't care to learn the bells and whistles, it has a lot of modes that allow you to just preset and shoot and let the camera do the imaging. Since photography is a big hobby of mine, I'm enjoying learning it's features and are shooting more and more in manual. I like being able to tell the camera what I want instead of just letting it decide for me. I'm certainly still learning but so far I'm very pleased. In my research, I looked closely at the Canon G11 which, in my opinion, had one other feature I liked which was a hot shoe to be able to put an external flash on (or put on a pocket wizard and set up the flash somewhere else), but my main concern was having the portability. I chose this camera because I can keep it with me and that's worth more to me than having to carry a larger camera. If I want to do that, I'll take my DSLR with me. The S90 has a small pop up flash that is adequate for most needs. I'll have to admit that it takes some getting used to where to put your fingers when holding the camera as the pop up flash pops up right where you tend to want to hold it (top left hand corner from behind the camera). I had read about that quite a bit in other reviews. They're right! But it's not insurmountable to get past. I have experimented some with the small flash and found that (1) you can adjust the amount of flash coming out of it and that helps in toning down the flash for just a fill flash on a sunny day and (2) If you lay a napkin or the end of a handkerchief over the little flash that pops up, it really softens the light that comes out of it. My wife and I are going on a cruise later this year and I really wanted something I could take along easily without carrying a bunch of camera gear with me. I think this is going to do the job just fine. Not to mention I've gotten some great impromptu shots just going back and forth to work. I have no idea how sturdy this camera is or how long it will last in the day to day world, but so far so good. I would recommend this camera to anyone wanting to have that camera with them that goes beyond what a cell phone will do (at least at this point in time). With technology, who knows huh? The nice thing about it is, if you want just a point and shoot, it's here and if you want to continue to grow and learn more about it's features and other tricks you can do with it, it's capable of that too. The best of both worlds!! Enjoy!!! Hope this helps some! 12 21 2010 Still doing a great job! I've (gasp) dropped it onto concrete once. Still taking great pics!!! I really like the flexibility and the features. No regrets whatsoever with this little camera! I carry it with me every day (I bought a nice leather case that goes on my belt) and it's so easy to just take out quickly and snap a shot or two. I walk 3 miles each morning and I take it with me for some great sun rises and fog shots.

I've agonized about which compact camera to buy, the G11 or the S90 for a couple of weeks. In the end I bought the S90 and some of the reviews really helped me, so here's my contribution to the people making that decision today: Do you own a DSLR? Definitely go with the S90. Are you looking for a camera to take in your pocket? No doubt about it, go with the S90. I've used the G10 and G11 and, believe me, there's NO WAY you are taking them in your pocket! The big differences between the two, which I'm fairly sure you all know by now are: - The focal length (105mm for the S90 and 140mm for the G11) - The manual controls - The size - The hot-shoe (only the G's have them) - The flash Well, let me start by addressing one of the main complaints I've been reading about, the fact that the rear wheel is "loose"and that you can change your definitions without noticing it. It was a concern when I bought the camera and, to my surprise, it has NEVER been an issue while shooting. I don't have small hands and I don't know how other people hold a compact camera, but for it works like clockwork, no problem whatsoever. I even dare to say that if it was a bit harder to move it, it might take from the easiness of changing your controls before shooting the picture. The difference in focal length doesn't bother me. Would it be nice to have more on the S90? Yeah, sure. But is it a concern? No, not for me. I'm strictly against using the digital zoom, but on the few times I tried just to see the result, I confess I was a bit surprised (on the good side) by it. The manual controls are exceptional, the combination of frontal ring, back ring and shortcut button make it easy to change configurations and control the camera. And for those of you wondering about the speed in doing it, I can say that I've been taking pictures to make a book about the life guard service here and it's all about speed. Sometimes I take the S90 to the beach instead of the big DSLR's because people won't even notice me taking pictures with it, and the DSLR's always cause a fuss, specially when people are being rescued and are ashamed to be seen in that light... As for the size, I bought it to have a everyday camera always with me and this is the perfect one for this. A couple of friends decided to buy one after seeing mine (one of them is abandoning his G10 for it). And I was very, very pleasantly surprised by the image quality and camera quality I got with the S90, I never regretted choosing it and now, after having handled a G10 and a G11, I think I would be mad with me if I had chosen the G11 instead of the S90. Some reviewers have questioned the built quality of the S90, but I don't have any complaints about it, and it has been living in my pocket for over a month now, receiving some fairly rough treatment sometimes. As for the shutter release on the S90, yes, it is in a bit awkward position to be sure, but after one or two days with the camera you'll adjust to it. Is it a serious problem? Not even close! Regarding the hot-shoe and flash: well, I own two DSLR's, so if I want to put a big flash on top of the camera, I'll take the big one. It might be different for people who are buying this as their only camera. I hate flash and avoid using it always, even bumping the ISO to the moon, but, on the occasion I used the in-camera flash I was amazed by it's power. When I'm shooting "professionally" I tend to go with the RAW + JPEG mode, but sometimes I prefer to use the strict JPEG mode and it has a very interesting color control that helps eliminate the need for working the files later on. Anyway, you can change that configuration in about 2 to 3 seconds if you need to (the RAW/JPEG, because the colors are even faster). A lot of reviewers and photographers talk about the S90 exceptional AutoWhite Balance, but I don't really like it, I tend to prefer choosing presets all the time (I don't like the auto WB in my NIkon's DSLR's either), but that is also very easy and fast to do in this camera. Well, that's about it. I'm sure there are other reviews discussing the technical details more deeply, but I've been a VERY HAPPY S90 owner for the past month or so and I'm sure glad that I chose the S90 instead of the G11. To tell you the truth, I don't see much reason in buying the G11, as it is not a compact camera, it is not a DSLR, it is not lightweight, so it's a middle everything. But the S90, and I've been hearing the same opinion from others for the past weeks, seems like the queen of compacts for now (I hope the manufacturers start a "fully manual compact" cameras war now). I believe that, for most buyers, the S90 will always be the smart choice!

I bought this camera because I want something combining both the picture quality of my Olympus C4000 (which has very good pic quality, but pretty bulky )and portability of my Nikon Coolpix L4, and also can shoot good indoor light low pic for items my wife sell on-line. I should say the low-light close up pictures are very impressive, at least compared with the other 2, and with ISO 800, there is not much grains, and the pictures shot with regular 60W floor light looks like being shot under directly sun light, and details and density is pretty impressive with accurate color. however, to my great disappointment, the pros stop there, except that benefit, this sturdily and beautifully built camera (made in japan)with exhaustive features and settings can barely beat Nikon camera (4MP, bought 4 years ago for around $150)in terms of picture quality, especially in the density and feel of space. there is easily detectable flatness and softness in everything in pictures shot under various light conditions leading the pictures to a blurry pixels after zooming in a few times in PC screen. the different density and texture of material is almost non-existent in pics shot by this camera. to me, this $400 so-call point and shoot only next to SLR is a joke considering the value and performance it offers. yes, as to the color accuracy, I can tell that the Nikon camera color is on cool side, while the Canon is on warm side, both of which are within acceptable range, but the picture quality of the latter is much much worse. if you really like the features and craftsmanship of a Japan made camera, and believe will be very happy with slightly better pic quality than that of a good camera cell phone, you may still want to consider this. otherwise, as long as you're not completely blind to what a good picture should look like, I strongly suggest you stay away from it and try other choices, which, at the price range of $250-400, are available in abundance.

SUMMARY: For those that are seeking excellent photo quality, this camera trumps its competition. Also, this camera will suit you well if you like to shoot with different scenes, tweak settings and/or customize things. On the other hand, if you're looking for something very simple, small and/or low-cost, then this is not the camera for you. PREFACE: When it comes time to make a big purchase, my husband and I seek out the best of the best. We always do lots of research and read countless reviews. This research has made it clear that in the world of compact point & shoot cameras, Canon stands out above the rest. And right now, the best camera available in this class is the Canon Powershot S90. (For those interested, our favorite trusted camera review sites are: [...] and [...]) Why is it the best? There are too many things to list here... Here's a link to a very detailed review: [...]. MY REVIEW: For me personally, the most important selling points were: 1.) LARGE CCD SENSOR - The sensor is much larger than your typical compact camera sensor, and it is a CCD which is superior to the more commonly found CMOS sensor. Normally you will only find this type of sensor on a digital SLR (DSLR). As a result, the photo quality from this camera rivals that of my Nikon DSLR. The photo quality is spectacular, especially in low light. You really have to see some sample comparison photos to truly appreciate it. 2.) CUSTOMIZABLE "SCENE" - It has your typical automatic and scene modes, but also has a customizable mode like you will find on DSLRs. This gives you the ability to tweak the settings exactly the way you like them and save them as a separate "C" mode - easily accessible on the top dial. 3.) CUSTOMIZABLE BUTTON & LENS RING. Have you ever been frustrated with the number of steps required to change certain settings? Well this camera allows you to customize the functions of the "S" button and the ring around the lens so you can set up easy shortcuts to the settings/features you use most often. Personally, I use the "S" button to change shooting mode (single shot vs. continuous vs. timer), and I use the lens ring to control exposure compensation (to make photos lighter or darker). 4.) LOW LIGHT CAPABILITY - I am usually never happy with the way photos turn out using the flash on a compact camera... The lighting just tends to look unnatural. So whenever possible, I shoot with the flash off. Since this camera handles low light so well, I almost never use the flash. I am just blown away by some of the photos this camera has taken in low light! Again, you have to see it to believe it. 5.) HIGH RESOLUTION DISPLAY - With most compact camera displays, when reviewing a photo it's usually hard to tell if the focus was correct, among other things. But the high resolution display on this camera shows excellent detail and reproduces color well, thus giving you a much more accurate preview of the photo. Some downsides to note: 1.) POOR BATTERY LIFE - Just order a few compatible generic batteries and always keep a charged spare in your camera case. I do this with all of my cameras, regardless of their battery life. There's nothing worse than having a fantastic photo opportunity and a dead battery! 2.) POOR ERGONOMICS - When holding the camera in your right hand, your index finger falls naturally on the mode selection dial, not the shutter. This can be annoying, but as you use the camera more, your muscle memory puts your finger in the right place. Also, it's really easy to turn the lens ring, thus changing the outcome of your photo. I have found no resolution to this problem other than to be careful. 3.) SIZE/SHAPE - It's a little less compact than many of the compact cameras available these days. However, it has to be larger to fit the big sensor in there, so I'm willing to make that sacrifice. Also, the fact that the lens sticks out makes it a bit awkward to fit in certain cases or to tuck away into a purse or pocket. Overall, I am thrilled with this camera! It continues to amaze me and give me that giddy "I LOVE this thing!" feeling. :)

Canon S90 IS is one of Canon high-end / advanced Canon Powershot compact camera. Its unique characteristics are slim, low profile body with great noise control in high ISO plus 28-105mm f/2-f/4.9 bright zoom lens. The other advantage is the camera is very pocket able. It fits in your jeans' pocket. IMAGE QUALITY AND ISO Canon S90 IS has 1/1.7' sensor size which is slighty smaller compare to its main competitor, Panasonic LX3 (1/1.63"). From my test, S90 IS image quality is very good across focal length but dynamic range (the difference between the brightest and darkest parts of an image) is limited . This is also a problem most of digital camera out there, but S90 is slightly worse compared to competitors. However, regarding noise control and handling, S90 IS is excellent. The new algorithm works very well to reduce or erase most (if not all) chroma-noises which degrade image quality significantly. Image shot at ISO 1600 is very usable for regular print and web. BODY & HANDLING Canon S90 IS has a slim, low profile look, so it is very good for street photography. It does not attract attention like digital SLR camera. For control, it has two main dials, both of them are round. One is located in the lens, and the back of the camera. The back dials also function as four way buttons. This design is similar to Samsung WB1000 design. Front ring dial can be customized for several options: adjust aperture/shutter speed, ISO, exposure compensation, manual focus, white balance or zoom. The front dial is not like zoom barrel in the lens, it is not smooth, instead, it has several stops point. There will be a "click" sound to let you know if you hit the stop. I usually use the lens dial to zoom. There are five stops in the dial: 28mm, 35mm, 50mm, 85mm and 105mm. All of them are popular focal lengths. I found this is much better way to zoom rather than traditional way (pull a lever on the shutter). It is faster, less noise and accurate. It is great for learning how focal length affect perspective and distortion too. Mode dial is harder to change because they have put some resistant to it. It is to prevent accidental switch. There is also a shortcut dial which you can customized to many function such as AF servo, intelligent contrast, face detection and many more. Canon S90 has 3' 4:3 ratio LCD screen with 460k resolution. It is similar to Panasonic LX3, but better than typical compact camera. It is worse than Samsung WB1000 which has AMOLED screen (over 1 million resolution). However, build quality is not up to par with leading advanced cameras such as Canon G11 and Panasonic LX3. It made by metal but it feels plasticky. I have a sweaty hand and it registers my fingerprint! Also because of its flat design, there is no place to secure your grip. But overall ergonomic is not bad. OPERATION & AUTO FOCUS Start up and turn off time is fast. It only takes around 1.5 seconds for each. Compare to LX3: around 1.75 seconds, Ricoh GRD3 : 2 seconds respectively. Auto focus is typical compact., around .75 second, will take more time if you point to low contrast subject. Camera operation is very fast and very responsive upon instruction. COMPETITORS Panasonic DMC-LX3K 10.1MP Digital Camera with 2.5x Wide Angle MEGA Optical Image Stabilized Zoom (Black) Panasonic LX3 is an arch-rival of Canon S90 IS. It shares same concept of bright and wide zoom lens. However, there are many differences between the two such as the focal length, build quality, image quality and handling, please read Panasonic LX3 vs Canon S90 IS for complete comparison. Samsung TL320 12MP Digital Camera with 5x Schneider Wide Angle Dual Image Stabilized Zoom and 3.0 inch OLED Screen (Black) Samsung best advanced camera is similar with S90 in one way, they are both compact and has great handling. Samsung WB1000 has AMOLED LCD screen which is a lot clearer, Samsung also has wider and longer zoom. However, Canon S90 IS is better in low light condition. Canon PowerShot G11 10MP Digital Camera with 5x Wide Angle Optical Stabilized Zoom and 2.8-inch articulating LCD G11 is a big brother to Canon S90 IS, it has superior control and body handling, but it is much bigger in size. CONCLUSION Canon S90 IS is a great choice for photographer who like a lightweight, pocket able compact but doesn't want to skim on image quality and control. It has very good operational speed and have some great customizable options. I especially like the zoom ring dial on the lens, which has Digital SLR like control. S90 IS is also superior in low light situation. However, Canon S90 Is also has a downside, such as below average build quality (relative to competitors) and limited dynamic range. Subjective rating compared to other advanced compacts in 2009 * Image quality 4/5 * Body handling 4/5 * Performance 5/5 * Features 3/5 * Value 5/5 Please check my website for image sample, ISO comparison and more reviews.

I purchased this camera in early december 2009. I have had it a few weeks. I bought it because of reviews that I had read and because on my previous overseas excursions I brought the cumbersome Nikon D70. I had never been interested in a 'point and shoot' camera before because of what I perceived as the lack of controls for shutter speed and f stop. Now, I am travelling and it is truly a pleasure and joy to have it strapped on my belt almost all of the time. I have now shot about 300 images. What 'sold' me on this one was also the high regard in the reviews that I read for the special 'low light' setting. It really does enable the photographer to shoot in low light situations and although there is typical color shifts, the resolution and lack of pixalation is quite good. It is very cool to have that option. Also, it is very small and Canon makes a case that is perfect to strap on your belt. It is so light and easy to carry that I bring it with me day and night. I had read many previous reviews that thought the 'wheel' control on the back of the camera was too loose and that it may change your settings too easily. At first, I thought this may be true but after some experimentation, I realized it was a genius design if you use "Manual" setting and also for flipping thru your saved photos and viewing them. The beauty of the wheel is that when you are shooting in Manual mode, you can spin the wheel to control the shutter speed. This allows you to look at the image and see it progress from light to dark or vice a versa. In my experience, the shutter speed doesn't matter as long as you are not shooting moving objects as long as you can control camera 'shake'. The f stop is the creative control for most images and you set that via the control ring around the neck of the lens in the front. Using the control ring for movement frees the photographer from thinking about 'the average meter reading and the plus one minus one, etc. that usually happens with an slr. Then you have to check depth of field and it is at least a two step process to see the effects. If you want to change depth of field, you will have to move the ring in the front, but you can see the effects right away and you can easily change the feeling of light with the 'loose' wheel in the back by changing shutter speeds. The other advantage of the loose wheel in the back is for viewing your saved photos. There are at least two ways to view them. One is by tapping the left side of the wheel to go backward and the right side to go forward. However, by using the wheel and rotating the wheel which moves very easily, you can quickly go thru many photos like you are flipping thru a deck of cards. Another recommended adjunct to the Powershot is the Canon case I purhcased which is specifically for this model camera. If you have a belt on, it slips securely onto the belt and is very easy to open and close. So convenient and compact and solid. The only thing lacking at this point for me is a smooth transition for the zoom lens. I use the control at the top and it is a little jerky and hard to control for exact framing. There may be an alternative method which I haven't discovered yet. This is my first point and shoot and it is a winner. Highly recommended.

(Updated to appease the bashers who reject the notion that anyone can disagree with them and, according to them, anyone who does is clearly uninformed. Since when did individualism become an imperfection?) Overall this is a nice camera and, as with most of Canon's line, most of the features will be rather familiar. Aside from the flash being a rather awkward place, the camera will satisfy most buyers. I bought this camera several months ago and began taking pictures in various modes and scenes, and I also took the same pictures with my Canon PowerShot SD800 IS. Before buying the S90, I also tried the SD980 IS. I've been using Canon PowerShot cameras for more than a decade and after taking over 2000 test shots, I feel confident in saying that Canon's current product line is nothing short of a disappointment. It's hit or miss... (As a non sequitur, under no circumstances can you use AUTO mode! You MUST turn the mode dial and use the adjustable settings.) Shortly after the first few test shots, I contacted Canon customer support because I noticed that the newer cameras (mentioned above) did not have SUPER FINE jpeg compression. A representative told me that their Japanese developers have eliminated the SUPER FINE compression ratio and all their cameras have only FINE and NORMAL compression. That would be like buying an HDTV that only displayed SD. Yes, I know, the common user WILL NOT notice a difference...(as someone else pointed out in their review). ***Similarly, I know plenty of people who can't tell the difference between 720p and 1080p. If you buy this, or any of Canon's current product line, be warned, most of your pictures will come out severely noisy, flat, blurry and unfocused. Indoor shots are not acceptable; however, outdoor shots (taken on a clear day) came out looking really nice. Some of the reviews here are from people who either do not have the "eye", or have limited knowledge of Canon's previous camera line. However, don't take my word for it, drop the money and see for yourself. If you have a trained eye, you'll see it! Again, if you allegorize this to HD movies, there are still plenty of folks out there who cannot tell the difference between a Standard Def movie and a High Def one. Before buying this camera, do you research! Go to Canon's Website and peruse their current line; you can also download the PDF instruction booklet. Look through the documentation and search for their JPEG compression; if you only see "fine" and "normal" then don't buy it if that is important to you! Canon has really proven to be a disappointment to their most loyal consumers. I understand this camera also records in RAW format, which I haven't discussed here, but that is great for anyone who wants to go into post-editing all the time. It does provide a wider range of post-editing options, however in my experience, the images still looked very much the same. (Users can record each shot in RAW+JPEG.) I realize this is a P&S, but I've had P&S cameras in the past that produce much better images than this one, with colors more vibrant, lines sharper, better contrast with more depth. I realize this review is going to get bashed but at least I'm not just restating all the positives that have already been stated in countless other online review site, and at least I ACTUALLY OWN the camera (some people post reviews and don't even own the item!). To anyone who is going to bash and bully this review, do so not at the risk of accentuating your ignorance and intolerance towards other's ideas.
