Re-exposure step during reversal processing

[charlotteRF]

To keep it short, I see such a huge variety of techniques, and conflicting instructions.

For Fomapan r100, their kit says to leave the film on its reels, and re-expose through water for 30 seconds from a meter away
For the Ilford Reversal process, it says to take the film off the reel, and rexpose for 30-60 seconds from 46cm away
The scala kit says to do so for two minutes through water, 45-80cm away.

The Ilford instructions also say that you can safely provide two-four times exposure and still get good results, and that slight fogging is the issues for overexposure.

Is the re-exposure step so flexible that all of these techniques will produce good results, no matter how you do it?
And does anyone have examples of a slide that is too exposed during the re-exposure?

I've only processed Ektachrome using reversal exposure (E1 and E3) I used a photoflood back in the day. A few years ago I experimented with Fujichrome and an old, but healthy E1 kit. I used a LED flashlight and got good results.

I don't think it's too sensitive to too much light, within reason.

Probably not with LEDs, they reference 100w incandescent bulbs, the only one I have that isnt LED is 275w, so I will have to adjust accordingly

You must consider that the silver halides left have lost part of their sensibility after being bleached in the permanganate (the original sensibility is partly restored in the metabisulfite clearing step), so the light re-exposure is not that critical as you have experienced.
