I'm trying to train myself to do the 'repeatedly pressing C' thing, but I can't help but continue what I usually do: Walls up, roof on, pause, take picture. I think I just don't want to have to sift through masses of screenshots. I can spend ages trying to get the best angle. Admittedly, some of my better pictures were actually tooken with the game unpaused!
Hey, you know what is annoying? Well, you know how sims can slightly turn their heads or change position when you pause them? The most annoying thing ever is probably when you pause to take a picture and then they shift out of the position you were trying to capture!!
