Review on 📸 Vello White Balance Card Set: Achieve Perfect Digital Photography - Medium Size (5.1 x 3.9) by Quintin Boner

gray balance cards should be in a neutral tone. There is quite a blue/green compared to other manufacturers. It's nice to have grey/white/black on top, but it's only useful if you're not trying to go for a neutral color. I think they are more suitable for portrait photography (white gives a bit of a warm tone to the image). Not suitable for neutral product photography. I'm comparing the color with a ProSpec card (maybe a little "warm" in tone) and an X-Rite Colorchecker datasheet. (The photo shows the 3 gray cards I currently have - it's neutralized to write a color check - you can see how "non-neutral" Vello is
