The GIMP is a horrible program for processing photographs using your wonderful Pentax DSLR because you are limited to 8-bit colour. It also has no colour profiling capabilities. Use Cinepaint (
CinePaint) when you shoot RAW. Use ufraw
UFRaw - Home to convert to 16-bit TIFFs and manipulate 16-bit (or even 32-bit), not 8-bit files.Cinepaint also supports HDR.
Another amazing, free, 16-bit , free Linux program, is Lightzone.
Light Crafts
To manipulate RAW info and embed colour profiles in your images, use exiftools.
ExifTool by Phil Harvey. This program can also automatically file your pictures on your HD.
Another 16-bit Linux program is GraphicsMagick (
http://www.graphicsmagick.org/), which is command-line based. I use it in conjunction with custom bash-scripts.
Here's an example of a picture processed exactly the same (except for size) using GraphicsMagick and a custom bash script I wrote. Bash scripting is easy and once you've written one script, you can use it over and over again. A massive Linux advantage. Notice the colour difference in the way the golden light is shining on the transformers. Every picture you process to 16-bit instead of 8-bit is clearly and remarkably better. Save your pictures to png to save a little space, keeping the 16-bit colour and making them accessible through your browser. A great way to view your 16-bit pictures is with qiv
QIV - Quick Image Viewer - Homepage (for Linux, Sun, FreeBSD and HP-UX). Don't waste the capabilities of your camera using an inappropriate program like the GIMP. The GIMP is a tool for web developers or P&S users.
