Uploads. Texas Tea. Swimming pools, movie stars. Stuff we can look at other than Times new roman to see if the writer knows what a properly balanced image looks like? I'm sure Marty does but I'd just like to see so I have a ground of reference while reading emails. Something to click on when the words get thick. In the old days before people did this and or had websites or other upload playpens we'd have guys will all kinds of ideas. Some of them sounded really impressive. Week after week month after month. Words. Brow beating opinions from out of the blue. Some of these high tech talking guys ended up not having a clue what a properly placed image looked like. Or how to spot a print. So we stopped worrying about their opinions so much or why we didn't have a clue what they were talking about. Or why their differential equations were different than ours. And some of the less glib guys were solid image makers. So then when they said something we listened. After we saw their pix. Or at least uploads. Which I think kids do well at at the age of 9. A paper print takes a few more years maybe. Sooner or later not its nice to see the proof in the pudding at the end of the day. The idea of Neopan 1600 only having a half stop more speed than Tri x just doesn't click with me. I've gotten a full 1600 out of it with bunch of developers and dilutions tungsten and daylight low pressure sodium and candle light. Full shadow detail with all kinds of prints in the darkroom or when scanned out of the Epson. And I think over exposing is the single worst thing you can do in black and white film photography. Digital too maybe! A quick glance at an image quickly betrays that. You get crushed upper tones which are darned impossible to uncrush certainly in the darkroom. But many are pretty handy with a histogram when they scan and or photoshop. Mark William Rabiner markrabiner.com
