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

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.

Works fine

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.

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.

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.

Just the right size to keep in your camera bag and with a lanyard to keep it at hand when being used. Should be on every photographers shopping list.

The cards have a hue to them and are textured.As a result, they are less accurate than simply clicked a neutral point in the image.I tried to use in the studio and started laughing immediately.The only positive I could say about these is that they are not the single worst item I have bought on Amazon yet.DO NOT BUY.

Simple. Does the job. I removed the strap and keep the cards in a camera bag pocket. Simpler still. It would be nice if they were a tab bigger but then they'd be a tad less convenient, too.
