Terry, it's quite simple. I process my film in my darkroom.
First off, I don't shoot color film, except for rare occasions. For color, I use digital. So, let's take a look at 35mm black and white processing. First off, I purchase Ilford HP5 which is currently listed on B and H for $89.99, So, let's say $90.00.
Ilfotec DD-X developer is $26.38 for one Liter.
Kodak Fixer is $12.95 to make one gallon.
The breakdown is such:
100 feet of 35mm film yields 18 rolls of 36 exposures. That is a total of 648 exposures.
With 1 Liter of developer, I can develop approximately 50 rolls of film, or 1800 exposures.
Thus, $26.38/1800 exposures=$0.02/exposure approximately
With 1 gallon of fixer, even if I limit it to doing the 50 rolls of film, is a cost of:
So, the final cost per exposure is $0.17. This is slightly higher than my initial post. The price of Ilfotec went up a bit.
I'd sure like to know where you get film and processing that cheap. I believe I'm paying about .85 cents a frame for b&w 35mm. That's develop only...
