I have to pay $5.50 to develop (no cut, just develop) a roll.
Now I am consider developing B+W rolls myself out of curiosity and if it's cheaper per roll, that's marvelous.
So, my question is, in your experiences, how much does a roll of film cost if developed in your own darkroom? and which developer are you using?
I do make my own developers ( only time a degree in clinical chemistry has paid off). The basic source book for this is Steve Anchells " Dark Room Cookbook" and once you get into it, you can start modifying processes and chemistry to suit your shooting style. Only part that I still buy as "store" product is
the fix as I hate making it from powder.
If you buy in bulk ( Sodium sulphite, carbonate in 10 lbs bags, metol or Phenidone in 1 lb cans as well as Hydroquinone in 1lb cans) you cut your film developing cost to pennies. Calculating with the fix it costs me about $ 0,80 to do 5 rolls. I go through 450-550 rolls a year so the developing cost is minimal compared to the cost of film.
I you restrain yourself from getting fancy and stock up on the basics you can also make vastly improved paper developers from much the same chemistry. Mass produced developers have to be manufactured for packaging and storage while if you make them from scratch you dont have to worry about that. Only expensive part that you need is a digital scale, the rest is basic stuff.
Most of the stuff is non-toxic (reasonably so!). In the "good old days" people used ingridients that makes you wonder how we ever coined the term "old photographer"!
Ilford makes a great developing agent "Phenidone" and it is quite potent as well as being non-allergenic. One of the developers that I mix is called PCK and it uses 0.3 grams of Phenidone in 500 ml of the A stock bath. That is enough to develop 30 rolls of Tri-X so a lb of it will last a long, long time. The other components are Vitamine C powder ( ascorbic acid) and Kodalk. The formula was concocted by Patrick Gainer " unblinking eye.com" and it is very similar to D-76/ID 11 with similar times and slightly better grain.
