I'm going to be intensifying a few negatives with selenium in the near future, and would like some tips on how to go about it.

Ansel Adam's The Negative suggests pre-soaking it, fixing, toning with a selenium/hypo-clear mix, and finnaly hypo-clearing and washing.

Is the re-fix really necessary? Could I just wash, tone, and wash? Can it be done is open light, or should I do it in tanks?

I've done prints before, and I believe it was a soak, selenium, fix routine (but I could be wrong).

All and any help is appreciated
