You can find a selection of my photographs on my 500px account.
My photo workflow is strictly linux-based and relies on a number of freely available tools. I download the files from SD card with Rapid Photo Downloader, which automatically creates the necessary folders. For culling I use Geeqie, for tagging JPhotoTagger and for editing RawTherapee and GIMP. I also made some shell-scripts, which make day-to-day photo operations a lot easier.
