This was prompted by the Ilford and Kentmere thread and is an offshoot of that post.
I've come to believe that recently there is a wider range than ever in what it costs photographers in different geographic areas to process black and white 'film' to say nothing of tradtional printing, even if it is 'digital' printing on black and white halide archival stock as opposed to 'RA' type papers.
Considering that chemistry can vary tremendously in cost depending upon 're-use', manufacturer, quantity purchased, use of anti-spotting/streaking agents, and equipment I am interested to know:
If you develop your own b/w film in small batchs -
1. How much do you spend per roll/image to process film and is this for 35mm, 120, 220, sheet film?
2. How much time do you spend per week or month on average processing your film?
3. Do you feel you lose any significant percentage of exposures to processing errors (light leaks, bad timing or chemistry, chemical contamination, etc.)?
If you print your own b/w either contact or enlarger -
1. How much do you spend on the average print including paper and chemicals?
2. Do you spend more or less time printing than processing the film? If you scan your film and then process digitally directly from the negatives, note that or if that is a portion of your work flow.
For both of these, your initial setup of space/darkroom, tanks, trays, tongs, table, measuring/mixing devices, safelights, enlarger and spare enlarger lamps, gloves, timers, and all those other little goodies can be split up over 1000 prints, or for the total rolls or images for a year for calculation. If you've been doing this long enough that that is a low number and you are willing, just indicate how you calculate your 'budget'.
I'm curious to know how this currently (1Q 2008) compares to the 'business cost' for a dip and dunk lab (few are left that do much b/w it is sad to say) or for a custom lab that buys chemistry in bulk and uses fresh chemistry and tracks water usage as a portion of its cost analysis.
This if purely for personal curiosity and to maybe give a realistic gauge for the 'home brewing' crowd to get an idea of what they may be investing.
Other than chemistry in large batchs, I haven't bought anything for a few years as everything I use is stainless and my safelights are filtered fixtures that take regular incandescent lamps.
Thanks for any particpation you may undertake and I'll post later my 'calculations' for the latest batch of Ilford, plus an extrapolation of what that might cost on 'average'.
