Can c-41 color negative film be developed in black and white chemicals?

I would like to develop black and white film but have a lot of color film exposed.Can I develop c-41 color negative film in B%26amp;W chemicals? I don't care if it does not come out in color.

Can c-41 color negative film be developed in black and white chemicals?
Yes, you can. You get a relatively low-contrast negative with a heavy, milky orange mask that's extremely hard to print through.





The image will be there, though.





The times I've done it, I've used straight D76 at 100 degrees for around 5 minutes with continuous agitation. The high temperature is necessary to promote proper swelling and developer absorption into the C41 emulsion, which is considerably harder than conventional black and white emulsion.





You'll also need to fix at 100 degrees for about 10 minutes.





When you first take the film out, it will look almost totally opaque. When it dries, there will be an image there, although, like I said, it will look sort of milky. This can't be avoided-the bleach step in the C41 process removes the part of the orange mask that makes it look this way.





Developing in black and white developer is actually quite a common technique for salvaging images taken on old film which required a long-obsolete process.
Reply:The only thing that I can suggest is to have them developed normally - use your computer to convert it to greyscale. Easy enough...
Reply:I really wouldn't suggest it. They aren't made for each other. I agree with some other people, that you should just pay the little bit to have someone develop it in the proper chemicals. Because your film isn't really going to turn out very useable if you try it in black and white chemicals.
Reply:It's really not worth it. Try getting some color chemicals or spend the $2 a roll to get just the negatives developed by a lab.
Reply:Im not sure what you are asking so I'll answer both. You can process the film itself in b/w chemicals such as d-76, etc. but it's highly uncooperative. If you are asking if you can make black and white prints from color negatives. Yes you can.





Experimentation is always worth it not matter what. That is how new, great things are discovered. Try it so you can say you have at least.
Reply:i did by accident once and it was hard to print onto the lightsensitive paper even with high contrast filters. its better to develop it in the right chemicals.
