During my last cross-processing (XPRO-5), I used a blue filter to replicate a tungsten balanced film. This also created a nice contrast between the blue filter and the red tone of the film. This time, I had used an orange filter, which is a complementry colour to the usual tint of cross-processed Kodak Elite Chrome.
However, it seems that the orange filter was too strong for my desired effect, resulting in images similar to red-scaled film. Canon EOS 600 loaded with Kodak Elite Chrome 100. 28-135mm with orange filter. Cross-processed in C41 at a nearby photo-lab. Scanned with a Plustek OpticFilm 7400 at 3600dpi. Photoshop work was minimal.
