so i want to develop color film...
I'm interested in developing c41 and/or e6. I am interested in develop-only as I have no immediate interest in printing or projecting my color negatives or slides. I have no interest in professional scans either. I would be happy to develop the negatives and then scan them with my consumer flat-bed and display the internet jpegs. OK, I know this is apug heresy but I had to make this clear because the answers to some of my questions would vary on my expectations.
1. What is the difference between a pro lab and your local drug store? I do not know much about color development but I figured that it is a standardized process and the labs just get the same quality ingredients and equipment (I can be wrong, this is my assumption). The only variable, I guess would be the operator, but I don't feel that it really matters if you send it out. I can see that there is going to be a difference if you want to get prints/scans, develop other formats like 120/4x5, use other services like pushing and pulling, and etc. But for the same services/films, is there going to be a difference. Now, I use a pro lab because it is conveniently located and I don't shoot enough film to go out of my way to make things more economical if a drug store were cheaper. So this question is for my curiosity.
2. Is there a difference in the quality of different chemistry? I'm talking about the general stuff vs propriety blends. Like tetenal vs fuji/kodak. Tetenal seems to be more user friendl but what is the expense? More grain and uglier colors? Realistically I would only use the general stuff because it seems cheaper and more user friendly. I also figured that minute color shifts can be corrected in photoshop. Grain would be less of an issue because I would use 120 mostly. If it matters, I am interested in Kodak Portra in C41 and Fuji Provia in E6.
3. So I would use tetenal, most likely. What is the shelf life of the chemistry for e6 and c41? Part of the dilemma is that I only shoot 1-2 rolls a week so i don't want to wait months to develop a stock-pile. If I were to go on a trip then maybe I can just buy the chemistry right after thet rip or something...I'm wondering if e6 chemistry is more or less stable than c41 too...I have no strong preference for one or the other but if c41 is easier to develop at home then I'd rather focus on c41 and just send out my slides.
