I have an RD1s and have posted several pics on this thread in the past: and I have been "away" from RFF for the last several months due to life, but I find it so refreshing and inspiring to see new owners/users of the RD1s with such great results. This is a 6 MP champ that I have always admired, and continues to be a legit digital camera despite technological advancements in digital photography.
Hillary, I really love the first two pics above: the BW has a subtle glow to it in the background, and you captured the man's expression perfectly. The second pic also has a really nice color tone/resolution: the detail/resolution in the foreground with the softer color tones and bokeh in the background. i used to have a Zeiss 28/2.8 that I used on the RD1s, with very good color results, and that is what your color pic reminds me of. I would be curious what glass you used in the first two shots and if you did any PP?
