DGK Digital Kolor Pro 16:9 Chart - Set of 2 Large Color Calibration - Video Chip Charts / 18% Gray White Balance Cards

My child is studying cinematography in college and a problem she often faces is no clean blocks of color to set color balance. The large card is too big to carry around unless you fold it, and the small card is too small to be useful. But the middle card is about 5"x7" and fits just perfectly into her gadget bag to use in the field. The color chips appear to be accurate. I suggest keeping the card inside a protective sleeve or manila folder when not in use.

It really helped me get a better handle on my "white balance". I can see the difference in my white balance settings.

The colors on the cards are not consistent between each card! The large card was printed, with banding from the inkjet visible, and the small cards were also printed. The middle card has color swatches affixed to it; and it is color-correct (checked against a Pantone chart). Setting each of the cards side-by-side-by-side, there are very apparent differences on colors and levels of grey. Taking a photo of all three cards separately or together shows the differences as well. The only useful card is the 5x7 (middle one), which is the only reason that I'm not returning everything.

It's nice to have a color chip chart but it's so small that if you're cameras are at FOH, the card isn't very helpful. Also, the card is printed on stock that isn't much thicker than construction paper so I doubt that it will hold up very well. All that being said, it is inexpensive & sold as a pair so when one gets too beat, just throw it away.

I'd probably be happier if I hadn't run the cards through some tests. Remember that this item is a pair of identical cards. The problem is that they are not really identical. I set up a controlled situation in a darkened room and lit the cards with a single daylight balanced LED photo light. I first manually white balanced my camera (a Canon consumer) and then recorded both sides of both cards. When I ran the clips into Final Cut X I found that they were quite different based on the vectorscope readings. My methodology involved isolating the primary colors (second row up on the product image) and viewing the scopes. Not only were the luminance levels different but the colors were quite different. I then isolated the third of the four gray color chips and found that they were close enough to be satisfactory. The skin tone (first of the two) hit the skin tone line on the vectorscope nicely. If you know what you're dealing with these can be made to work but if you're doing anything that requires precision then be sure to calibrate your system and know what you're dealing with beforehand.

Very nicely made, would be helpful if they had a non-glare surface.

It works for its intended purpose, good quality and color is good.

Paper is a little thicker than a copy paper, but non-reflective and workable. Wish it is like the old Kodak Grey Card I purchased some time ago which uses hard 1/8 thick cardboard...
