It's like people in a gigantic prison with the pillars being the cell bars...
I really enjoy your stark contrast rendition of your subject matter. I would love to see a print of this some time, as I believe it would hold a bit more information than my computer screen. As dark as they are, it seems you've got almost full shadow detail.
Nice, different, exploring view of a day-to-day subject. I like your approach a lot.
Thomas - I just came back from the darkroom and this one printed very nicely. Exactol is a very nice developer with a great tonal range and beautiful highlight density.
