Tipster of the Week: The Inverted Equation of Cross Processing

If you're in for more experiments and wanting to do something with your rolls of film a bit differently other than baking it, cutting it into pieces and even fermenting it; how about cross processing? I know, this is much common now in Lomography next to cheddar cheese, but there is a scientific way of doing it! And all you need to know about it is here, courtesy of our Tipster of the week!

Guide to cross processing negative film – a recap by eggzakly

The biggest challenge when cross processing negative (c41) film in e6 is low contrast. Cross processing slide film increases the contrast, whereas cross processing negative film lowers the contrast. But no worries – all we need is a bit of applied film theory!

Here are the quick and easy steps to success:

1. Underexpose rather than overexpose. Negative film can be finicky and very light sensitive when cross processed, and overexposure lowers contrast.

2. Have the lab push the film 2-3 steps to increase the contrast.

3. Try out lots of different films. You get very different results from film to film, some turn out prettier than others, some are more sensitive to light, some are lower contrast than others and need to be pushed more.

4. Have fun & enjoy your amazing results!

    Great work! The Fuji films, somewhat predictably, seem to give superior results.

    And for @dogma, I have started doing my own E-6 and C-41 processing and it's really pretty easy--in fact, I think even easier than black and white. I buy prepackaged kits from Freestyle Photo here in California

    I really like the results you got with the Reala and Agfa - it's inspired me to do some more experimenting as I've always had a liking for the dreamy subtlety of neg X-pro. It works so well with your shots and pulls together the double exposures beautifully. What camera's did you use? kdstevens - thanks, I didn't know it was possible to colour process at home and found this great how-to link http://www.wikihow.com/Develop-Color-Film I'd love to give it a try, does anyone know about kits/chemicals available in the UK?

    i knew it was a good idea!! i asked some of my local labs to do this and they said they wouldn't do it cause the image would turn out all white and i would want my money back.. damn them
    besides, very few labs process (or sell) slide film, but i'll just keep insisting on different shops, someone will have to do it!
    thanks for giving me the certainty that it is a good idea!!
