>>2942981Scanning is 7€ up here. So if a scanner costs about 250€, it takes about 36 rolls to pay for itself. For me that happened earlier this year. Also, output is hirez TIFFs or w/e on your RAID array, instead of generically post-processed JPEGs on a CD.
Development is another 7€/roll regardless of format and chemistry, and for large format it's 3€/sheet. For black and white with HC-110 dil. B (~10ml/roll) you get 100 rolls out of a one-liter bottle which costs about 30€ from maco, so it's 0.30€/roll to dev. Fixer is a bit more expensive per roll esp. given that 1+4 rapid fixer spoils in 3-4 months, but we can still count about a 6€ savings. For C-41 it's exactly 0.54€ per roll (compard digibase kit, 5l = 100 rolls for 53-ish yurobucks). Also, you can play funny development games like push/pull development, semi-stand, and what-not; and it's quicker and a fun part of the hobby. This pays for itself slower, in terms of euro per roll, than scanning.
Bulk rolling is the easiest question. Generally cheap film costs under 3€/roll of 36, and expensive film costs around 4€/roll of 36, in bulk, bought 30m (~18 rolls) at a time. This makes for a savings of 2-3€/roll, so with a daylight loader costing up to 120€ (or next to nothing if bought used), this is the slowest thing to pay for itself.
Each of these steps gives you more control, and more stuff to do. So for /fgt/, except mf and lf people, each step is almost a necessity even if it weren't also a cost savings.
