After reading the previous thread on split filtering, I would really like to try it.
However, my Opemus III enalrger demands that I slide out the neg carrier to be able to change filters (I use an Ilford set), and I will loose registration between the two exposures.

I understand that it can be done by holding the filters between lens and paper, but my feeling is that this will degrade the print quality (If one will place a partially diffuse/reflecting surface in the lightpath, what for high quality lenses?).

Any other suggestion?
