There's no rule that says you need to hold your camera straight. Turning it ever so slightly can add a little curiosity to the photo. Try it...you'll be surprised with the results.

Not sure? Go ahead and shoot it straight on...and then CROP the angle in post-production. I do that a lot because I never know what size print I'm going to be asked to make. That's where aspect ratios come into play. I think I already blogged about that...So crop it with an angle and if it doesn't work, just undo the crop.

Think of it like this...look at the way you see the world, and then try to see it a little differently. We take for granted what we see, and rarely take the time to study it. Art is all around us and sometimes you need to tilt your head slightly to notice it.
