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

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

The plastic colour cards are of good quality and are not flimsy bits of plastic. The colours are great and enable you to get your white balance correct. Great value too.

These are great little cards and works well. However, it most definitely is a little bit reflective. Holding it a certain way in the light makes it look silver instead of grey, and that's a problem. If you place it correctly it works great but you have to make sure that it's not showing the shiny reflection. If placed correctly. It works just fine. It will last a long time even when out if the field. Use with care but worth the money for a quick easy solution to custom white balance.

Handy to have in your camera bag when out where’s there’s difficult light to deal with. Photograph the grey card to get the correct white balance.

Not much to go wrong. Has been useful to calibrate/check camera meters and set white balance

Bought just for the grey card to keep in my wallet, it has a slight satin shine, I prefer grey cards to be matte finished. Just be aware when you’re using it that there’s no reflections on the card. Handy to have but I’m not sure it was a photo/videographer who designed them.

I clip this on when photographing garments that have 'awkward' colours. I'm not a pro - but a volunteer taking pix for a charity to sell on line. I can't swear to 100% colour accuracy - it looks a tiny bit blue to me - but certainly good enough for pix that will be viewed on screen by the general public. Very convenient to have in shirt pocket.

While this isn't as accurate as a ColorChecker or such like, it will quickly and cheaply get a good idea on the white balance. I'd say the grey side is slightly warm if anything. You can manually set your camera WB using the white side, or take some reference photos (I use the white and the grey sides) then click to set WB on your photos during post-processing. Folds up nice and small so no excuse for not carrying it in the bag.

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。

Initially, I found Ms H. Brannon’s observation correct about the white card having that tinge of colour, whereby she gave this set a one-star rating. However, I was viewing the card in artificial light at the time and that tinge disappeared when I viewed the card in natural light, i.e. the card turned "pure white" in day light. I deduce that the differences in the whiteness of this white card and Ms Brannon’s black/white colour test card depicted in her photos, could lie in the different materials used in their manufacture and their inherent properties. I find this set convenient to use, even in inclement weather.

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...
