More than I have time to print...
I was an artist-in-residence ion Zion National Park, April 2018 -- nothing to do but photograph for a month outside my backdoor. I exposed roughly thirty 5x7 sheets, forty-five 8x10 sheets, and twenty 11x14 sheets (~95 total sheets). I had a much lower success rate with the 11x14 (lack of experience and some bad film). I have printed perhaps 12 negs so far, of which the Park has one for their collection (an 8x10 pt/pd print)...so over-all with all formats presently 12:95 (1:8), with a possibility of bumping that up more. (PS - not including the Rolleiflex B&W work).
I spent a month in southern Chile last Dec/Jan and exposed 32 sheets of B&W 5x7 film. Many were doubles (changed filter and/or exposure). I printed about 6 of them, though one needs more work. This is 20 percent more than I anticipated before the trip (I'd be happy with five). I might be able to print others if time and desire permits, but now it is about 1:5.
Several decades ago I spent about 6 months on a bicycle in NZ with a 4x5 -- exposed 70 sheets, made a 20-print portfolio...16x20 prints. I also had some nice images that were unprintable due to negative damage, so it goes. I would whittle that down now to 12 prints as I am getting fussier in my old age. I suppose if I scanned those negs, fixed the nice ones with the high humidity static discharge marks in PhotoShop I could bump the portfolio back up to 20 again, but they'd be inkjet prints and I have better things to do. But for now, 20:70, or 1:3.5 with a 20 print portfolio, or 1:6 with a more solid 12 print portfolio.
But I find that I am open to experimenting -- 'wasting' a sheet or two to try a different approach to composing the light...that sort of thing. And since I contact print in Alt processes, as I change the process, the negs often need to change too, so that hits my success rate. Using all sorts of films, old and new, makes like interesting, too. All worth it.
