You know when you look through a viewfinder you close the eye that isn't touching the eye piece? Well, I can't do that! I can't even wink with one eye, I just can't, I am jealous of people that can, lol, I always wanted to wink at someone

Anyhoo, is anyone else like me? Does it affect camera use? I am so use to just looking at a viewfiner and taking a pic. Can you take pics through the viewfiner with DSLR? Sorry if this sounds like a strange post, I hope you know what I am saying!
