Hello, at last year’s Fineartforum Paderborn, Klaus Wehner presented a black-and-white reversal kit based on his own formula. Is it available to buy yet, or does anyone know when it will be?

Hello!
I emailed Klaus Wehner, and he sent me the development kit. I used it to develop some expired Scala roll films from Bulgaria, following the instructions. It was really exciting and worked a treat.
Best regards, Thomas

Unfortunately, I didn’t bring enough chemistry kits with me to the last fineartforum.
As a result, some of you who were interested didn’t get one. I’m very sorry about that.

The reversal chemistry (as well as my new negative developer, the ‘Wehner Developer’) is available to buy directly from me.

I’m delighted to hear about Thomas’s positive experiences!
Anyone who follows the instructions can expect high-quality results from Agfa Scala, Adox Silvermax and Adox CHS 100 II (all at ISO 200/24).
However, exposure of photographic paper (in pinhole cameras or large-format cameras) and then its development into a positive using reversal chemistry is also an interesting way to use the chemistry kit.

I’m happy to answer any questions!

Best regards

Just a quick personal note:
?
I, too, occasionally have a poor memory for names.
Personally, I have no problem at all with being addressed by the wrong name from time to time.
It does happen occasionally… no big deal.
?
However, this is now the second time a wrong name has appeared in a headline in connection with me.
In this case, it’s confusing because it concerns specific matters or ideas.
Something incorrect sticks in the mind quickly. When doing research, this can easily lead one astray.
?
Fortunately, everything is spelled correctly again in the body of the text.

Hello,
I had the chance to witness the reversal process for photographic paper at the last fineartforum live event. Portraits were exposed onto photographic paper using an 8x10-inch camera and then developed immediately. The results were truly impressive.
I still intend to make photograms and then print them onto baryta paper. With the reversal process, I could skip the intermediate negative and work directly on baryta paper.
I’m currently testing the Wehner developer. The initial results are very promising. It suits my personal taste, sharpness and a wide range of grey tones very well. As soon as I have something presentable, I’ll report back here on the forum.
Best regards,
Renate

Thank you, Renate!

Photographic papers do vary considerably in terms of their quality and characteristics.
?
For the direct positives that were exposed during the portrait workshop at the last fineartforum in Paderborn and subsequently developed using reversal chemistry, Adox MCP paper was used.
?
This paper has produced the best results so far. That is why I would recommend this paper for reversal processing.
With other papers, you may not achieve good results quite as quickly.

Warm regards from Paderborn

Thanks for the great video!

I’d like to add two points.
€
1. It isn’t strictly necessary to prepare the baths using demineralised water.
Ordinary tap water is usually sufficient for this purpose.
€
2. All films are designed to reproduce an average contrast of 5 zones.
(Exceptions are surveillance films and microfilms. These may be able to reproduce 3 zones with sufficient detail).
€
With transparency media such as slides, the matter is somewhat more complicated.
A transparency medium can theoretically reproduce an infinitely high contrast. Here, everything depends on the brightness of the light source and the maximum density of the slide.
If you have a high-intensity projector (light source and lens), the projection can still render the high densities that are no longer visible on the paper.
This is why all slides appear particularly brilliant and nuanced on the screen.
My reversal process achieves exceptionally high maximum densities and is suitable for high-quality projection.
Paper prints can only reproduce this high brilliance imperfectly.
€
Anyone who has the opportunity to visit the fineartforum in Paderborn from 4 to 6 November 2016 will be able to see black-and-white slides in the projection and on the light table.
Large-format slides are a rarity.

Warm regards
Klaus
