Pixel Perfect Camera Color Correction Card - 5" x 7" for Photo and Video - Reference Tool Grey Card Target White Balance Exposure Temperature Color Calibration Chart (2-Pack)

The original Color Chart is big, delicate to handle and requires extra care to work as needed and avoid physical damage during use. These smaller versions of the chart not only have the same quality in terms of Color Calibration, but the size makes it ideal to pack for travel situations and location work in general. It can go in a camera bag! I store it in the original box for extra protection It is recommended for those photographers and videographers shooting outside the studio, but it also works perfectly fine indoors

I believe it is an excellent product at a fair price. We use it to calibrate samples of flowers and other plant materials. We use it together with the OpenCV library. You can find my code on GitHub; the name of the repository is OpenCV-Color-Calibration.

The "gray" tones aren't even close to gray. This is printed on a cheap inkjet printer in RGB, not even CMYK, so the grays and blacks are literally purple. There are no true neutral tones in this card, not even close. A total waste. Don't buy.

On the flip side of the 24-color squares is an 18% grayscale rectangle, for down-&-dirty color correcting. The 24 set is great for when colors absolutely have to be perfect. I was doing a coffee table book of an artist's work and got each piece spot-on every time. Well worth the price.

Hard to figure out how to use their site instructions is confusing

I needed a new color chart but wasn't trying to buy one of the $100-$200 ones for how little I use it. I am able to use this in Davinci Resolve with no issues what so ever to help with more accurate color grades. This is a great color chart to start out with before deciding to invest into a more expensive unit.

Good quality, and a good thickness of plastic material !

It feels flimsy and poorly made. No case for protection from scratches or dirt
