remember too that if you're pushing reversal, there's a limit to how far you can go because of the chemistry itself, and the tolerance of the emulsion to being submerged for so long. i've always heard it's really unwise to go beyond two stops.

also, every stop you push the exposure, you lose another two stops or so of latitude, so you have to expose super-carefully

good luck!
