Your research offers several explanations for why my first attempt at perborate latensification didn't seem to have a great impact:
1. I was using Delta 400, and so your remarks about faster film showing less effect are probably apt.
2. I didn't check the pH of my perborate solution prior to using; could have had something to do with it.
3. Slow shutter speeds. I can't remember, but I may have been shooting at 1 or 2 second exposures.
Did you discover, or do you know, whether the perborate solution must be used as a one-shot, or can it be re-used several times?
