Bear with me, I'm experimenting

This is one of only 4 shots today - the others were more rubbish versions of the same idea. Took a very brief detour on the way home from work to shoot something in RAW, then wrestled with adding a plug-in to PS to recognise my camera's file format, then experimented with the sliders, then wrestled again with working out how to get the file into JPEG. It's not very straightforward, but I'm reasonably confident I'll remember for next time! Just need to learn what the sliders are all for!
