Hi! Can anyone help me?
I was trying on custom white balance with the grey card bought recently. Read from my 7D's manual on pg. 71, it says 'Look through the viewfinder and the area within the dotted line should cover a solid-white object'...Manually focus..blah..blah..blah! My question is, I don't see any dotted line? should I just cover maybe 90% of the viewfinder so as I can use the remaining area outside for manual focusing?
