Selective Exposure Correction in GIMP
I took this photo in the middle of the afternoon in harsh sunlight so getting the exposure right was difficult. I tried several different exposures using exposure compensation and watching the histogram, but because much of the deer was in shadow compared to the full sunlight that the foreground was getting, I had to choose to expose for the deer and let the rest get a bit blown out. According to the histogram I was getting all the data, so I knew I could fix it in software later.
So, how did I fix it? Well, this is a first for me, but I made a video showing how I did it. I meant to upload it to Flickr to try out their new video upload capability, but it's over 90 seconds, so it went on YouTube instead:
...this was my first video ever and in retrospect I should have said what menus I was using as I clicked on them. Perhaps I'll get better at it over time.
Lasso Select tool: In toolbox window
Invert Selection: Under "Select" menu
Curves Tool: Under "Tools" menu > "Color Tools"
