Right guys I wanna give cross processing some 120 a go

what would I get if I ran colour slide through black and white negs

Atm I am set up for black and white negs but looking at colour slide chems soon, so colour print film would cross nicely in that?

Intrigued about how to set this up
 
I know it might sound odd but it's not always consistent, i'd tend to do some clip tests first. Double up on the first shot then process the first exposure see if it's what you like and continue.

I've only ever been happy with crossing colour neg in E6 in the past.
 
If you're talking about putting slide film through B/W chemistry, then I'm afraid you won't get any thing, it don't work that way.

Colour slide film through C41 chemistry = yes
colour Neg Film through E6 chemistry = yes
B/W film through Colour Chemistry = NO (strips the emulsion clean off!)
 
Processing colour film in B&W chemicals will yield almost unprintable negs One of the difficulties is that the film contains a yellow filter layer, which is removed during the tail end of the colour process. You aren't doing this so this filter stays in place and gives you very very dense negs.

You wont produce any colour dyes as the B&W developer does not contain the special colour developing agents to react with the dyes in the film.

By all means try it , but use the developer as a one shot item. You won't strip the emulsion off the film as colour process run at 38 C and you'll be working at around 20 C the pH also is much higher in Colour developers than normal B&W chemicals
 
Cheers guys,

so if I have slide chems and neg film will I get slides or negs out (also vice versa)
 
iirc (It's been a while...as in over 20 years :lol: ) if you process slide stock in c-41 you get a negative image on a transparent base, processing neg film in E6 results in a positive image with a orange-tinged base.
 
cunning, so I can get slides by crossing neg film

I can't print colour ya see and this simplifies what chems I need to keep and know
 
wait until someone else verifies what I said, i'm fairly sure that's what happens, but i'd hate to think you're placing orders on the strength of it... :shrug:

Been 20 years for me too, but that's pretty much how I remember it. The most popular was E6 film through C41 Chem (well, in London in the late eighties anyway) :)

Sounds interesting, but what does it actually look like, what are the benefits and differences, has anybody got any examples of the results?
