Do NOT take the film to a lab and run it through C-41. You'll have one extremely irritated lab manager.(posted 8993 days ago)Here's the scoop:
You use C-41 DEVELOPER. That's right, just the developer. The rest of the process is your standard fix, wash etc.
Try 9'/68F EI 12-16 as a starting point. Use ordinary inversion agitation; you don't have to do the Technidol cocktail-shaker stuff. Then follow with a water rinse (no stop), then your standard fixer, wash, HCA etc.
If that's too contrasty for you, you might try shortening the development time or diluting it 1:1. There's not much wiggle room; TP is sort of an all-or-nothing film.
You can buy Kodak C-41 developer in a gallon size; don't worry about developer starter etc. For just fiddling around you might try begging enough developer for a tryout from a local lab.
C-41 dev results in a speed and curve shape similar to Technidol, Rodinal 1:100, Ethol TEC and Burton 195, but it's not prone to uneveness, streaking etc.
BTW, the reason for not using stop is that it often causes reticulation with TP.
