It is a white balance grey card, and it is not for setting exposure. So guys beware of that.

Overpriced for a couple small pieces of plastic but does the job. Not sure that the white and black cards will ever be used. There are instructions included written by a feminist Several sentences begin with “She—-”. Funny.
* star for the neck strap. The strap has 10 Opteka logos on it. It cannot be turned inside out to hide the advertising so I will not use it. They also put their logo on the gray card itself. All this advertising is annoying. You may want to do some tests to determine if you really need a gray card. I found that the preset WB options on my Canon were very good except for artificial lighting situations.

Every serious photographer needs a white balance card or color checker. Let me say that again. EVERY SERIOUS photographer needs one. It makes in camera fixes a breeze, and does pretty well after the fact in photoshop as well. This is cheap, small, and gets the job done. If you don’t have a studio or can’t afford a bigger card, this is highly recommended.

I am a little disappointed in these cards for a couple of reasons. First, they are smaller than I expected – but not smaller than advertised. They are the size of a business card. That makes them convenient, but not useful for setting the custom white balance in my Canon dslr cameras since Canon wants you to focus on a white or 18% grey object that completely fills the viewfinder. The cards also do NOT have the “individually numbered certification label and focus target patch” as promised in the instructions (but not the ad). I think the instructions, titled “DGC-Introduce” are written for another product. Since I shoot mostly raw, I will be able to use the cards as a reference when the subject doesn’t include anything with a pure enough white color to be used as a reference in processing. But a bigger size would serve my needs better. The “convenient neck strap” will end up in the trash.
