I will be doing a chase car for Team Zeiss at the World Series of Birding, beginning at midnight tonight and going trough midnight on Saturday, so…this post will most likely have to cover two days. (You can follow my adventures, and the adventures of Team Zeiss, on Twitter, @singraham or @zeissbirding_us, or see both twitters and blog posts at zeisssports.wordpress.com.)
That said, these are Pink Lady Slipper Orchids from Rachel Carson National Wildlife Refuge in Wells, ME, taken last Sunday. The top shots are from a sunny patch facing the river, right at the edge of the forest, which bloomed early…most of the flowers at Rachel Carson looked like the bottom shot last Sunday. I was there early, and the low sun was in and out behind clouds, so the light on the full blooms is quite different than the light on the unopened buds.
All were taken with the Canon SX20IS at 28mm equivalent and Super-macro. Exposure varied with the light but was mostly at ISO 80 and ISO 125. The top three at F2.8, and the bottom one at f5.
For the sunny shots, a bit of Recovery in Lightroom. A touch of Fill Light, Blackpoint to the right, added Clarity and Vibrance, Sharpen landscape preset. For the bottom shot, similar but, clearly, different amounts, plus cropping for composition.

Great detail.
