Anwenk Grey White Balance Card 18% Exposure Photography Custom Calibration Camera Checker for DSLR and Film

Just about exactly as you would expect. Easy to use, easy to carry (wallet, lanyard, other), and it seems durable enough. I think it was worth it to have, especially convenient for wedding days.

Good and affordable.

Very useful

White Balance -- very important if you want to have your colors reproduced correctly when you take digital photographs. It is truly amazing how many times the digital camera gets white balance totally wrong and your colors look weird when you review the pictures at a later date. My example is snow on a cloudy day -- digital cameras see blue, not white. I shoot photos in RAW format and do all my final JPEG processing (post processing) on a computer. The very first thing I do is set white balance. The second thing I do is exposure correction. Here is where these cards come into play. * White card -- to set white balance for the scene you are shooting. * Place the white card into the scene and take a picture, than take the card out and reshoot the keeper picture * In post processing, use the eyedropper tool to click on the white card and see the difference * Make note of the color temperature and use that number for subsequent photos taken in the same light * Gray card -- what is known as an 18% gray card -- half way between black and white * This color is what the camera strives for in exposure setting -- making everything fit 18% gray * You use this card in a scene to set your exposure properly -- converting your camera meter to an incident light meter * No need to photo the gray card, but you have to set your exposure using this card prior to taking the picture - exposure lock feature I have never used the black card. The color accuracy of these cards is good. They are small enough to keep in your shirt pocket and use in the field. They are made of plastic and clean easy. If you are having problems with reproducing accurate colors from your digital camera, these cards will help tremendously once you get the hang of their use. It makes color correction and exposure values as close to spot on as you can get.

This set of cards is just what I needed to do color analyses to determine seasonal palattes. Three cards included in grey (most used), white and black. Small portable size- each card is a bit smaller than the size of playing cards. Mostly used to set white balance in pictures on my computer.

Como fotógrafo, siempre busco mantener una calibración de color precisa entre tomas y cámaras, y este comprobador gris me ha funcionado excelente. El material se siente resistente y de buena calidad, el tono gris neutro es bastante exacto y ayuda mucho a ajustar el balance de blancos tanto en cámara como en postproducción. Es liviano, fácil de llevar en la mochila y se limpia sin problema. Ideal para sesiones en estudio o exteriores. Por el precio, realmente supera las expectativas. Recomendado al 100% para fotógrafos y videógrafos que cuidan la fidelidad del color en sus trabajos.

Great and practical card - unfortunately the neutral grey is off a little and not completely grey, compared to Kodak grey-cards which you can click in photoshop for a proper white-balance, these have a bit of a tone to the face when used the same way

fits in my bag and is super handy for 18% grey light reading

The metal ring inside broken after two usage. Not good

This kinda blew my expectations. I was expecting cheap paper cards (for the price) turned out to be 3 solid acrylic cards. They are about the size of business cards which I can see be too small for some photogs/videogs but their perfect for someone who is not in a studio (like I am). Their worth far exceed their cost in my opinion.

びみょーに、壁がクリーム色の部屋で撮影した動画が妙な色になって。 いじっても余計におかしくなり。どうしたらいいのかと調べていたら反射率18％のグレーを撮影してあとでホワイトバランスを調整するというのを何処かのサイトで見かけて。 試しに買ってみたところ、無いよりあった方が良いという色に。 すぐなくすので、グレーだけ5枚入りみたいなのがあれば良い。

Tarjetas de muy buena calidad, teniendo un lado con brillo y el otro mate-rugoso, perfecto para hacer balances de blancos en las camaras, y asi tener las tomas de video perfectas, tambien ayuda bastante en postproducción...

I've had this now for nearly 3 years and it's still going. I've open and twisted this more times than I can think so it's not going to break on you. Folds down nice and small, white and grey colour is pretty accurate with sometimes a minor change but helps get skin tones pretty accurate. Has a decent surface area to get white balance so functions how it should and is great value for money. Will definitely buy one again once mine goes to white balance card heaven
