I have been working with Jonathan Bailey and the spilt technique is wonderful, however, it has a mind of it's own and you will get blue , greens and rose colors all on the same print. The degree will depend on paper, developer and fixer used.
However, check out his site, the work is wonderful and very different than the average above average photographer. He favors toy cameras and the random results they produce. That along with the split toning is very "cool" and unusal.
