    Default Crossing Processing

    AFAIK, there are two types of cross processing: color negative film in slide chemicals ("C-41 as E-6") or slide film by the color negative process ("E-6 as C-41"). In photoshop, how do we get these two visual effects digitally? How are they different? Thanks!

    Basically if you cross-process slide film in C-41, what you would get is a negative image without the brown tint. The tonal curve would also be quite different. If you cross-process negative film with E6, then you're going to get a positive image due to the reversal process but with the brown tinge. Usually, most would cross process slide film with C-41 rather than the other way round, so in Photoshop you can just try inverting the colours and then tweaking the colour balance and the gamma to get a similar effect.

    Check this website out. This website offers Photoshop actions for download, and I think the one that might interest you is called 'Editorial Lomo'.

    If you have photoshop cs3, go to the curve adjustment and select cross processing option.
