OK something I was intending to do
Screenshot - shows jpeg & raw / raf
Bottom left shows the basic arrangement - Camera (X10) set manual with about 1 sec exp & waved over objects - I tend to stop movement at intervals during exp
Its all guesswork - after that its selecting an image then playing with it in various settings (I use Picassa) until something appeals - then its fine tune & more playing. Crops can occur anytime.
The first one on impressionist thread was a collage of about 6 images then given the treatment.
First & Third above are fairly straightforward - no collages just treatment. Gull added as collage in second.
