Tweaking nature photos with GIMP

June 9th, 2011 · No Comments · photography

(NOTE: I’ll be adding more to this post shortly.)

I have much to learn about the fantastic open source GIMP graphic design software. Although I’ve hardly begun using GIMP in the design of graphics for websites, I have been using GIMP almost exclusively for editing and tweaking my nature photos and other digital shots.

My digital camera (Olympus Stylus 790 SW, 7.1 megapixel) has a setting for landscapes (SCN, setting 2) that enhances the green and creates a more richly colored photo than the standard setting. I’d like to learn what variables are changed so I can recreate the effect or produce a similar one with GIMP.

After opening the image file in GIMP, the first thing I tried was this: I selected Colors – Color Balance and adjusted the middle of the three slider controls halfway towards Green. This made everything a little greener, including things that shouldn’t be green (e.g., Mike’s arm).

Next I tried Colors – Hue-Saturation, clicked Green, then increased the saturation by sliding the handle to the right. This appears to have worked: the canopy of leaves looked much better, and Mike’s arm was still colored as Mike’s arm should be colored.
