XDepth Raw Converter (XDRC) is a raw photo development and image processing software with integrated XDepth Raw and XDepth 48 image compression technologies. XDRC is capable of reading raw files from most DSLR cameras and allows conversion of raw data to its JPEG-compatible XDepth Raw file format, shrinking raw files down to one fourth the original size. XDepth Raw Converter is a professional-grade raw development software featuring a fully High Dynamic Range 96bit/pixel floating point rendering engine.
This FREE program converts RAW (in my case ORF type) camera digital files to other types - jpeg, bmp tiff etc and works well. Just open file and when you save - you get prompted for the output format you want and away it goes!! Probably does more but who cares - I can use GIMP once the picture is converted.
Cons
mmm XDepth sometimes seems a tiny bit slow but it is FREE and WORKS.
Summary
Want to edit RAW files and can't with GIMP (or whatever), use this program to convert first and away you go! Read the very good user guide quickly beforehand.
Best of the free programs I've tried

Pros
It does what it says. It's easy to use. It's free.
Cons
Some operations are a little slow and the sliders don't apply effects as you slide. You have to slide to where you think, then wait for it to be applied to see if it's how you want each time. Nothing major though.
Summary
It does the job it's intended to do and it's free. Worth checking out if you want an easy to use application for this purpose.
