Finally, i finished this picture from last summer. This image composed from 68 serial photos of same scene with different lighting. I've used simple flashlight with 3 LEDs (i use it also for back lighting of snowflake macro photos), with white semi-transparent diffusor, mounted after LEDs. Scene illuminated from different directions: from top, left, right, front, back, and different distances from flashlight to still-life composition.
When it was done, i've applied standard post-processing steps: noise removing, sharpening, color balance, local and global contrast enchancements. Overall, this work took many and many hours, but this sort of "painting photography" is really interesting task.
