Thx again, Rudy, Tony - and with greatest respect, rmann & DWT.
Tony, I seem to be zeroing in on agitation w/ the Pyro. 'Nothing new or dramatic, but getting sharp w/out having to back contrast way down. It was Andrew & yourself that recommended the soup & I can see it was for good reason. For any finished or shiny metal, I wouldn't use anything else anymore. Andrew mentions Obsidian Aqua as another fine developer, but having tried a bunch, I have a bunch to use up.
@hiho, thanks for all the kind references -- I still haven't gotten my color bit-zapper stuff up, so the gallery from my April visit to the Railroad Museum of Pennsylvania is currently pure B&W analog ... That was from the hastily arranged get-together a few weeks back (that produced All Wheel Drive). I'd like to go back some time; ideally with the Bronica, a tripod (assuming it's legal), and a polarizer, as lighting in the indoor part was complicated. There are some windows in the walls in one section and some overhead skylight sorts of things, but the visitor is frequently in rather dark narrow spaces between strings of RR equipment. (Another thought was to go on a cloudy day!)
DW - references are all true. I took about 60 frames, of which 3-4 aren't bad. The lighting seems like overhead sodium lamps - cold colored & leave alot of dark spaces. Where the light falls, the reflections mock exposure. 'Makes me appreciate what you & rmann had to gladiate to get the shots you did. Reflective metal can be a bugger for exposure. Truth be told, I'm not smart about artificial light yet. 'Still have at least 8 frames that excited me to look at, but couldn't capture the impact. You got the look I was trying for on the drive wheels & arms - combination of massive/strong/sensual tones. Another was like your crusader shot, but the end of roll chopped it in half. Sigh. I'll get there. The link will keep me busy for another hour or so. Thx for including.
