Anwenk Grey White Balance Card, 18% Exposure Photography Custom Calibration Camera Checker Video, DSLR and Film,5.3"x 7.28" (Large Size)

Very good product

Super

These super little cards are both handy and useful. My only reservation is that they have a slightly shiny sheen, which can be a problem under adverse lighting conditions.

I am an Amateur photographer and use a Nikon D7000. I had little issues with colour using the automatic white balance on board the camera but learning to manually adjust this and using the Grey card gave me accurate colour throughout the series of shots I was taking in my mini macro studio set up. The cards are good quality giving you black, white and the 18% grey I required for colour continuity. Nice cards and I thought a reasonable price, so perfectly happy for my needs.Anwenk Grey Card White Balance Card 18% Exposure Photography Card Custom Calibration Camera Checker Video, DSLR and Film,5.3"x 7.28" (Large Size)

Had it for almost 6 months now and this is literally what I've been looking for my shoots. Easy to carry and perfect for white balancing

Work perfectly,I use them for white balance when using a Astronomik CLS filer which produces a blue tint,when white balance set with white balance it becomes neutral

Biught as a gift for photographer. So unable to fill in details

I compared the Anwek grey card to a quality grey card branded "WhiBal" which I use for art reproduction and measured the colour difference in Lightroom. The Anwek card is too blue - by 650 Kelvin. If you try to use it for grey balance, your images will have a very strong yellow cast.I did not test if the claim of 18% reflectiveness is true. All three cards are very thin, bendy plastic sheets with a semi-glossy surface. I am returning them.
