I took one of the infrared photos that I took on my recent Sonoma trip and tried tweaking it a bit in gimp to make it appear more dramatic. Check out my photo gallery to see both my after and before pictures.
Basically, I took the original and stretched the contrast, then applied some color curve modification to make the darks darker and the lights lighter. I then cloned some of the existing texture to eliminate the vignetting that appears in the corner, and then did some local burn/dodge type modifications. I like the overall result quite a bit.
I didn’t notice this before, but you can see a bird just to the left of the rock in this shot quite learly. I snapped a picture of him later, but didn’t notice him when I took this picture.
