dlRaw-preview screenshots
Here are some screenshots of dlRaw-preview. They are taken under KDE 4.3 on Ubuntu Karmic Koala. Of course your windows could look differently, it depends on how your window styles are set. If you use gnome desktop, you can also alter this by changing the qt4 style.
The screenshots show some of the controls and the result of the filters you'll probably use on many photos. Starting with the dcraw settings like white balance and demosaicing algorithm, then basic corrections in RGB, local and global contrast, denoising and sharpening and some creative filters like adding a color tint or a vignette. The RGB curves are placed at the end of the pipe, to get the histogramm in final shape after the contrast and creative filters. On the second page two more screenshots show the effect of a conservative sharpening in 100% view.
