Was doing some cave photography this weekend with my K-5, and mistakenly took the following shot without re-adjusting the manual settings:
Oh well, wasted shot, right? Well, later, at home, I opened the RAW file in Lightroom, but before I deleted it, I thought, "Hmm, I wonder..."
Two tweaks later (Exposure +3.5, Luminance NR + 40), I came up with this suboptimal-but-actually-legible version:
I am pretty stunned, to say the least. That's more "leftover" dynamic range than my previous point-n-shoot camera had at its best...
(BTW: original shot was DA35MacroLtd, f/14, ISO400, 1/30 sec... I meant to open the aperture to f/2.8 or so.)
