Hi there,
Does anyone here have any experience with developing Neopan 1600 as a slide film (e.g. using the Foma slide kit)? Unfortunately, the Scala process doesn’t work with this film, as the Bleach bath doesn’t clear it within the standard bleaching time during continuous processing.
If anyone has experience with reverse processing of Neopan 1600 or T-Max 3200, I’d be interested to hear about development times and exposure settings.
Regards from Hamburg

Jün,
Are you sure the film isn’t being bleached in the Bleach bath, or are you perhaps confusing that with the grey backing on which these films are coated?
With this speed, all manufacturers use a grey-tinted backing in addition to antihalation protection, and you can’t ‘bleach’ that.
In other words: neither the TMZ nor the Neopan 1600 will become completely clear.

Hello Mirko,
I know that the slight greenish tint on the base film cannot be removed during reversal processing. However, it isn’t so pronounced that it would put me off using reversal processing for Neopan 1600 altogether. The problem isn’t the tint, but the potassium dichromate-free bleaching bath, which apparently isn’t strong enough to do its job within the normal bleaching time in the Scala development process for Neopan 1600, resulting in slides that look muddy. According to Dormoolen, where I had a Neopan 1600 exposed at 1600 ASA reverse-developed on a trial basis, the Neopan 1600 can be made as clear as is possible given the substrate’s colouration by using an extended bleaching time or a Bleach bath containing potassium dichromate. However, extending the bleaching time is not possible in the Scala continuous process because it is not economically viable, and potassium dichromate is simply no longer permitted within the EU.

PS: Perhaps you have another tip for me: I’m simply looking for a black-and-white film that I can expose at 1600 or 3200 ASA and process as black-and-white slides, and which delivers results that are at least comparable in quality to a correspondingly pushed Scala. The Scala pushed to 1600 ASA itself is too expensive for me to have developed in a specialist lab, as I’m already

Hi Jän,
The only thing I can suggest is: do it yourself.
Any other option isn’t because of the problem itself, but because of your budget constraints.
In other words: any alternatives are bound to be even more expensive than Scala +3.
Our reversal kit for 8 films costs 18 euros (I haven’t checked just now, so I might be a bit off), a developing tank costs 13 euros, a thermometer for five euros, and you’re good to go.

On that note: has anyone actually ever developed the Rollei hoch drei in reverse?
We’re looking at an initial development time of 25 minutes for negative film here. In this context, I’d be particularly interested in the secondary development time. I reckon you could shorten that if you used the original developer.

Hi Mirko,
That was exactly my intention, and the reason behind my original question: doing it myself. But: what would the development time be if the Neopan 1600 was exposed at 1600 ASA? I thought that perhaps someone might already have some experience with this and I could save myself the trouble of trial and error.

The Erstentwickler is a powerful and very balanced developer, comparable in its performance to Maco LP Supergrain.
If you already have development times for this developer, you can simply carry them over. I’d guess that the time without pushing is around the usual 7–11 minutes.

Thanks, I’ll start with 9 minutes to see how it goes.
Best regards
