Taking proper before/after pics

I really dont know where to post this, so mod move this thread wherever you think it belongs.

Does anyone have tips how to professionally take pictures of your progress to make comparison easy? If I try to take the same pics of my face later, the angle is somewhat off, making real comparison a bitch.

Well you pretty much just have to remove any variables… put your camera on a tripod in an easy to remember place for next time, like in a corner or something and stand so far from it. Or sit it on a table and measure how far away from it you are.
