I'm going to be getting another C-41 kit in the near future. I've used the Arista 1 quart kit in the past, but I'm intrigued by the Flic Film C-41 kit sold by Ultrafine. It's a powder kit apparently made by a Canadian company.
I'm especially interested in it because it has separate bleach and fix steps, but I haven't been able to find much in the way of user commentary or reviews. Also, the instructions don't appear to state how much developing time should increase with each roll of film.
I don't think you need to any additional time past 1st roll, 8 rolls is all that this kit will develop, maybe if you wanted to experiment add 20% for a 9th roll. I will likely order the same kit, it now cost $9.00 to develop one roll of C41 at my local shop, about $3.50 with a kit.
Flic Film is in Alberta. The guy owns a shop in the area and started making chemistry. I wouldn’t really call it a company so much as a store shop owner who adapted some formulas online and started bagging kits. It is questionable at best.
