Gary,

Yes, I agree that this is entirely different. However, one could preflash a holder or two and carry them for those high contrast situations. This could be done, if one wanted, before the actual exposure. Since what we are doing is breaking the film exposure threshold with non image bearing light.

Obviously for roll film users it wouldn't work the same as sheet film users.
