Hello,
for my upcoming trip I would want to include a grey card, so that I can do manual white balance under water with my Canon G7X. I know that I can use my palm or sand for this purpose, but I want to try it out with a grey card. The card is pretty big (20 cm x 15 cm) and I am trying to figure out how to carry it, so that it will not bother me. Do you have any suggestions for me? I'd like to attach it somehow to my right arm.
