To set custom white balance I go to Still mode, select wb, scroll down to SET, put the circle on a white or gray card and hit Enter (center button in wheel), it shows what the white balance is on the bottom - assuming the top number is from a previous setting.
It then offers where to store it, I select Custom 1 and hit Enter.
Whether I stay in Still mode or go to Movie movie the custom wb setting I just saved is not there, it is still on the previous setting.
Any idea what I'm doing wrong?
