DGK Color Tools Digital Kolor Pro 16:9 Large Color Calibration and Video Chip Chart, 2-Pack

Smaller than I thought but the colors are great

Setting white balance is not sufficient if you plan to do any PhotoShop work. Matching true colors in the same lighting conditions is essential. This is a set of two cards for color, white and gray balance.

It was bigger than i thought it would be. It still serves its purpose well it can just be hard to travel with because its not small and compact to stuff in a camera bag like i was hoping. its also paper/cardboard material so i dont feel like its going to last very long. i wish it was smaller and plastic so it could handle longevity.

Very handy for the price if you don't need a super expensive calibrated chart. This one will help you match dis-similar cameras. Wasn't protected in shipping. Came in a plastic bag, no cardboard, no protection of any kind. Was creased down the front. We made it work for us, but the lack of any sort of shipping stiffener seems ridiculous. Wasn't even labled "DO NOT BEND/FOLD"

This is somewhere between oaktag and cardboard, so you'll need a safe folder or box to keep them from the elements. But they are good for quick white balancing in the field.
