I learned about the very cryptically named c2g GEGL operation in Gimp from this post at the Linux Photography blog. I like to convert soft wide-open photos to black and white, but I’m not always happy with the results – when I increase the contrast to get the black parts like I want the transitions between black and white often get weird and eroded. c2g doesn’t always work well, but I especially like it when I blend a c2g’d layer back into the original image – the results remind me of colorized Civil War era photos. Here’s a before-after, the first with just a levels adjust and the latter c2g’d and blended back in.
I certainly wouldn’t recommend doing this to every photo, but I’ll probably at least give it a try now and then.
isaac…wedin dot org may be messed up. i logged in twice, but still get the mediation stuff on the comment section. not sure what’s going on there. anyhow, probably something simple. and hey…that photo transformation is VERY cool. looks like a painting…or, at least a whole lotta photo shop work. j
