Equipment
[edit]- Canon 5D
- 100mm/f2.8 Macro at f/20
- ISO 100, 1 second exposure
- Background illumination provided by 240watts of 6500K high-cri fluorescent. Highlight illumination by photoflash reflected off a 4ft x 1.5 ft white matt panel, additional highlight illumination provided by a distant tungsten light and a set of deep violet LEDs at offset angles to preserve an appearance of depth otherwise lost in the 2D image.
Processing
[edit]- RAW to 16bit conversion with dcraw
- Slight rotation
- Cropping to 4:3 aspect
- Gain to bring background to white.
- Minor cloning to remove sensor dust from background area
- Scaled to 2048x1536
