I love this idea I saw on this blog to make silhouettes of my kids.
Step one: take a picture of the person whose silhouette you want in front of a window. You should NOT use a flash, and even if there are things outside it probably doesn’t matter. It’s also not terribly important if the picture is a touch blurry.
Step two: I used ACR in CS4 to increase my exposure and blacks all the way. I upped the recovery a touch so I wouldn’t get too much light on the top of their heads.
Step three: I did some small touch ups to get clean up some of the white background and converted the images to b&w, then combined them into one. Voila! I’m going to do some new shots so I can get some really really good ones to frame for my house!
