So, just to brush up on technique, I turn on the LCD screen, hold the camera at face level and at arms length, then push down hard on the
shutter button in one fluid motion, right?
With regard to technique, I wear glasses. I find I look through the viewfinder over the top of the glasses, I think primarily because that angle puts my nose off the lcd screen, so there's fewer greasy smears on it. Pushing the viewfinder back on my glasses enough to be able to see all the info at the bottom of the screen in there is taking some practice.
