If I've told you once, I've told you a thousand times.
When having your picture taken, turn your body slightly (SLIGHTLY) away from the camera!
This slims your profile, and who among us can't use a little slimming. A new friend that I met the other day agreed to pose and illustrate this important photography tip.
Meet Larry the Longhorn. He's pretty wide (and horny too but we won't get into that in this post!)

With just a slight adjustment in his pose, Larry appears a little slimmer.

As he keeps turning away from you, you can see how nicely Larry slims down.

Considerably so, in fact!

Do ya see what I'm talkin' about now?
Nice job, Larry. Thanks.
