Not sure if I've got the right forum here, but here goes:

I'd like to try a touch of cross processing, I've got a roll of Agfa Precisa 100 slide film loaded, as this seems popular in cross processing circles.

Should I just shoot it at ISO 100, or under expose by a stop as I have read on some sites? One site suggest shooting it at ISO 200 for very saturated colours, once cross processed. I'm going for that very typical Lomo look, just for a bit of fun and experimentation.
