I initially took a series of bracketed shots at f/10. Heck, I thought I'd push the depth of field just to be sure of focus sharpness--lens' sweet spot be damned--and closed the aperture down to f/16. Canon T3i, 1/40", ISO 100, EF 75-300mm III @300mm. Autofocused using Live View at 10x magnification. Cable release to trip the shutter. Cam on a Benro A500FBH1 tripod. Used only Adobe Camera Raw post processing and nothing else. False color temperature--pushed it toward yellow and magenta.
