One side of the panel is 18% gray, while the other side is neutral white.

The panel collapses to just 1/3 of its full size, allowing it to fit in most camera bags. A zippered storage sleeve is included to keep the panel collapsed during transport. White Card White Card is basically used to define the white balance, which is often replaced by a sheet of white paper due to its easy access to materials nature. The correct exposure of the white card makes the definition of the white balance of the picture noise is so small that very conducive to define. However, the correct exposure of white card compared to gray card to be more difficult, - generally we recommend to use gray card to define the white balance. Why gray card, white card can be used to define the white balance? Because both are R = G = B. That is, as long as the card is R = G = B color, it can be used to define white balance, only in this way, they can be separated from the white balance information carried. 18° Gray Card and Focus Gray Card , - generally refers to 18% reflectance gray card. Since the camera exposure is based on 18% reflectance, we use the gray card metering to get the correct exposure. Another use of the gray card is to define the white balance. Because of the correct exposure values mentioned above, the gray card carries the correct white balance information. How to Fix WB In-Camera With a Grey Card The exact way of setting the white balance in camera with a grey card might differ from below, depending on the manufacturers. Check your camera manual or search on Google about custom white balance and specify your camera’s model. Place the grey card in the scene; Set the camera to manual focus; Frame the shot so that the grey card fills the whole frame. Don’t worry about the sharpness of the image. It will work fine even if it’s out of focus; Check exposure and adjust if you need to; Press the WB button while turning the main dial until you select PRE. Release the button. Press and hold it again until the letters PRE start flashing. Take the photo of the grey card before PRE stops flashing. That´s all! The camera has just created a WB preset based on the photo you just took. In other camera models, you might need to take a photo of the grey card and then select it in the Custom White Balance as the reference image. Exposure Measurement White Balance Calibration Here's how it works 1. Exposure Measurement: By metering the light falling on the gray card, photographers can determine the correct exposure settings for their camera. This is especially useful in situations where the light may be uneven or challenging to measure accurately. 2. White Balance Calibration: Gray cards are neutral in color, and this neutrality helps in setting the correct white balance for a photograph. Photographers can use the gray card as a reference point for adjusting the color temperature of the image, ensuring that whites appear truly white without any color casts. To use a gray card, you typically take a test shot with the card in the scene under the same lighting conditions as your subject. Then, during post-processing, you can use the values from the gray card to adjust exposure and white balance for the entire set of photos taken under similar lighting conditions. Review: Surprisingly well made! - I simply needed a reference card that's easy to store and take with me that didn't take up any room. This is like any reflector that has the metal frame that folds small and comes with a storage pouch. The frame itself seems well made and feels very durable. I have other similar size reflectors and it doesn't snap open like this one does. The color seems accurate and helps immensely when post editing for good color accuracy. I mainly use the gray side but the white side can be used at any time. Yes, there are some wrinkles on it but doesn't seem to affect the overall image quality. Glad I bought this based on other reviews. I've had more fancy full color cards but always found them cumbersome and had to be careful when traveling with it in its case but this makes portability worth every penny. Review: Works great! Solid purchase. - This works great and comes with small case to hold it. It folds up small and fits in the case so it doesn’t take up a lot of room in my bag. The quality is excellent and the color is the right gray. ## Features - Gray side: Reflectance 17.8%; Density 0.74 - for Max. deviation of reflectance: 2% - for Max. error in exposure measurements: 1/8 of F-stop - This handy double sided pop up 18% grey/white card simplifies the complex technical issues surrounding exposure and color correction when working in different lighting conditions.

I know it can be used for both. Just seeing what's more common with this.** A: So if I am reading everyone correctly, here, then this is how to use this thing; for jpeg shots, you set your white balance with this thing then you go shoot. So, if you change lighting then you need to redo your white balance before moving on. If you shoot raw, then you take a shot of this thing, then set white balance in LR or PS against that shot, and then use that for all other shots in the same lighting. If your lighting changes, then you have to take another test shot to set your WB with in LR/PS. Am I understanding that correctly? **Q: I ordered this card a month ago, and it folded down to a smaller size. This no longer looks to be the case. Is this now a different card?** A: It can be folded into a smaller size like a 80/110 cm reflector, we just do not fold & pack it any more. **Q: What is the difference between this one and a similar one with white/gray/black? And another one with multiple color squares that looks like makeup?** A: Hi, This one and the similar one with black/white/grey are used to adjust white balance on your camera. The other color square cards are used for color calibration. **Q: Is the "white" side appropiate for white balance?** A: I use the grey side for white balance and it worked perfectly. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Surprisingly well made! *by Z***K on March 11, 2026* I simply needed a reference card that's easy to store and take with me that didn't take up any room.

Solid purchase. *by E***N on April 8, 2026* This works great and comes with small case to hold it. It folds up small and fits in the case so it doesn’t take up a lot of room in my bag. The quality is excellent and the color is the right gray. ### ⭐⭐⭐⭐⭐ Nifty Product - Read on for how to get it to fold correctly! *by A***E on October 21, 2017* This a clever little product that meets my need perfectly. I used mine to perform custom white balancing in the field on my Nikon D600. It came in a small zip bag and pops open when you take it out. I mean Pop! It weighs like a feather and it's cloth over wire frame construction means it's very easy to set up against a tree or whatever in the field, set white balance, then pack it away. So it's both compact and under 4 oz., great for your gear bag in the field. The wire frame makes it less likely than a piece of gray card to blow away. The cloth means it's possibly cleanable as well. Just what I wanted for the field! Light, cheap, reliable, practical. My D600 read the grey face but not the white face. Here's how to fold it back up so it'll fit back into the pouch: Note that it is roughly rectangular with 4 corners. With both hands pinch two catty corners or opposite corners on the diagonal, doesn't matter which two as long as they're catty corner. Bring the 2 corners together so it's pinched together in the middle. You now have 2 corners together and it looks like a sort of butterfly shape. Holding the pinched corners with one hand, turn that hand inward towards you so the back of that hand faces away and the 2 "butterfly wings" face at you. Using your other hand bring the bottom wing up and into the middle so you can now pinch that lobe as well with the hand that has the middles pinched. Now holding all that with one hand, bring the other lobe over and down on top and, keeping it pinched bring it all together in the smallest size and slip it back into the pouch whilst keeping it all pinched together. A lot to write down for you, but do this once and it's a cinch forever! ## Frequently Bought Together - Lightdow 12 x 12 Inch (30 x 30 cm) White Balance 18% Gray Reference Reflector Grey Card with Carry Bag [Folded Version] - Anwenk Grey White Balance Card 18% Exposure Photography Custom Calibration Camera Checker for DSLR and Film - SanDisk 128GB Extreme PRO SDXC UHS-I Memory Card - C10, U3, V30, 4K UHD, SD Card - SDSDXXD-128G-GN4IN --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sk/products/1464784-lightdow-12-x-12-inch-30-x-30-cm-white](https://www.desertcart.sk/products/1464784-lightdow-12-x-12-inch-30-x-30-cm-white) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-24*
