First attempt at black and white reversal

Third attempt/roll developed last night. I used the benzotriazole with a new mix of PQ concentrate and the brown tone in the film is still there. I am thinking on either cutting or totally removing the potassium bromide in hoping to bring the tone to neutral. I will keep updated.

On a side note: I used regular, constant, inversion with the bleach this time

I don't know if you'll find this technical document, KODAK T-MAX 100 Direct Positive Film Developing Outfit J-87, helpful to get neutral tone, but it makes some interesting points:

In the section Adjusting Image Tone, it says "to obtain a more neutral image tone in processed films, you can treat slides with KODAK Brown Toner." This is interesting because a direct Sulphide toner is known to warm the tone and probably implies that the default tone from Kodak's reversal kit is somewhat on the colder side.

In the section Adjusting Contrast, it says "you cannot adjust the contrast of slides produced with reversal processing by changing the development time or temperature (as you can in normal processing of black-and-white negative films). Adjusting the development time or temperature will affect only the minimum and maximum densities and effective film speed."

Interestingly, the recommended EI for normal contrast in reversal applications is 50.

One thing that may have been covered, you MUST consider use a 3200k lamp. Any (ANY) blue wavelength light seriously runs the risk of solarisation. We've done hundreds and hundreds of rolls and learnt the hard way early on - its rated at 3200k re exposure to specifically avoid solarisation.

Anyway, sounds like you are having fun so welcome to the world of BW Reversal!!!

@Raghu Kuvempunagar: Sounds like that Kodak kit is the 180 opposite of my situation. Blue toned or just cool, I wonder. I remember that kit in the 90s but never gave it a shot for some reason. If I was to aim for E.I. 50 I might have to reduce the first developer by about 1:30 to 2:00. It could work.

@PolyFilmLabs: The bulb is rated at 2700K, slightly more orange. Soft white, 60 watt, 800 lumens. Many have warned not to do the re-exposure outside. A lot of blue there..
