Selective E-6 Reversal

[Stephen Frizza]

I have long considered experimenting more with an E-6 trick and am wondering if anyone here has done this.....

Processing E-6 in its first developer then washing it and rather than placing it into E-6 reversal bath or exposing it to white light, instead expose it to only specific wavelengths of light such as only exposing it to light between 600-700nm or 400-500nm and seeing how the selective wavelength re-exposure tampers with the reversal outcome.

does anyone have heavy experience in this or examples?

I would guess that the result is comparable to using colored filters on the camera or projector lens, but who knows.

This depends upon whether the sensitization lasts through the first developer. If it was like kodachrome, you would fog only the red layer if you exposed it with the correct wavelength of red light and thus would see only the formation of cyan dye. Green layer forms magenta and Blue layer forms yellow. If the sensitization dyes didn't last you would not see the fogging at all.

Normally the reexposure is done to completion. In this case I think that as in kodachrome you'd need to tightly control the reexposure.

I guess it would be easier with sheet film.
