Today I'm sharing a little before and after from the senior session I shot last week. I just sent out this gallery the other day. For seniors, I do more hand editing than for most family sessions. I tend to shoot more portrait-style work for seniors, with slightly more posing.
I try to keep it pretty natural, but do smooth skin, whiten teeth, and dodge and burn to bring out highlights and add depth.
I also removed umpteen flyaway hairs from the close up shots in this session. While I did try to keep an eye out and have her smooth & comb her hair before I clicked the shutter, shooting with backlight can make for an editing nightmare with stray hairs. All those finite details take a lot of time to correct in post-processing!
I did learn a new trick though, by duplicating the background layer in PS and adding a dust and scratches filter, I was able to use a layer mask to help paint over many of the flyways. Here's a link to a tutorial of this method if you're interested: Editing in PS.
