This was actually my first-ever for-real large format shot. Let me know what you think!
(Full res version here: http://findatlantis.com/elcapitain-mono-ll.jpg
The full res version was saved with lowish jpeq quality in order to keep the file size down to 5.5MB or so -- the original of course has no jpeg artefacts.
For the technically inclined, this was shot with a Cambo Legend 4x5, Nikkor-W 150mm at approx f/22 (possibly smaller, I don't remember), Better Light Super-6K back. Resolution was 6000x8000, bent 6 stops scale, 1/50s line time.
Note that this is cropped for printing with a slight bleed, so the composition assumes that the actual image will be mildly cropped on all sides. Monochrome conversion was done in Photoshop, otherwise there's not much to say about the development.
