New IR Film From Adox?

There is an article in German, in the latest edition of Photoklassik which seems to suggest that Adox is about to launch a new IR film with an ISO of 50. A copy of the Photoklassik page has been attached by a member on FADU. Other than ISO 50 and the statement that a full "Wood Effect " will be possible, the page by itself is sketchy on detail to say the least. It may be pure journalese speculation by Photoklassik of course but seeing two recent posts from Mirko and his announcement of a new web site has prompted me to mention this matter. Perhaps Mirko can comment on it.

ISO 50 would be very slow considering that there is quite a filter factor when shooting with an IR filter. However....

My thoughts as well, especially if the only way to get the true IR effect(Wood Effect) is with a R72 filter. Given that there is already an Ilford film with a 200 rating and a Rollei film that is 400, both unfiltered of course, then there has to be something sufficiently different in this new film to make it worthwhile, doesn't there?

R72, thanks, that the filter I was think of. Yes, this film would need something special, but maybe that something will be the low speed? I would think it would have finer grain than the 200/400 speeds already out there. Sometimes I really like the wild grain of SFX, but I could also really like that same image in the fine grain of a 50 speed film. The more choices the better!

Yes the "something different" may be as simple as finer grain and Adox's assumption that as most IR photography is done on tripods then the lower speed is not a drawback.

If the film's sensitivity extends farther into the IR region, it may mean that exposure times end up being shorter.
Remember, ISO speeds are based on visible light, but R72 filters block visible light.

Thanks, mitorn. I certainly couldn't follow the spoken German well enough to work out what Mirko said but the subtitled translation did not seem to say anything about a new IR film. At what point in terms of minutes and seconds did he make a reference to introducing a new IR film?

Thanks

Good point Matt. The trouble is that there is no curve of any kind shown or any mention of how far into the IR region the film's sensitivity extends.

The sub titles spell out that the slitter is why they will not be able to offer
At 33 seconds into the clip the sub title refers to their new "IR-HR" film. The slitter is not ready to go for 120.

So we got two hints:

-) "HR-IR" at the video
-) "IH-HR" at the recent Silvermax dev. time-table

"HR" would fit to the IS0 50 hinted at above (seen that classic IR films typically are in the Iso 200-400 range, though not the Agfa ones.)

Thanks, mitorn. I found it. It may be the way the translation has been made but to a native English speaker and reader it makes it sound as if the new IR film is already available as it is included in the same sentence as CMS 20 which is currently available.

To include a mention of a new, yet to be launched, film in a one line comment on a video about a splitter just seems odd

Oh it doesn’t get better if you understand the audio. To me, a native (Austrian) German speaker, it also sounds as if the film just has been released.

Hello pentaxuser,

the announcement was published in the current edition of PhotoKlassik, in the 'news' section. I am the mainly responsible author for this section. This news was given to me directly by ADOX CEO Mirko Böddecker. No speculation at all, real facts. This film will come soon. There are also already test films in the hands of photographers. I am also already testing this film, ADOX IR-HR. ADOX intends to offer this film in a complete set, a whole imaging system completed by filters and developer(s).
So just stay tuned .

Best regards,
Henning

Interesting, perhaps that odd batch of CHS100 that Mirko mentioned in the Partner forum lead to some testing with other sensitazion dyes and finding a balanced option for IR.

Wondering if, for practical or aesthetical reasons, it may honor HIE or Efke Aura without antihalation.

Thanks Henning. Having given the information to Photoklassik and with actual film being tested by selected users, I hope the actual release into a production run is close.

We work on several projects simultaniously (guess you knew that .
The video was taken a while back and we thought when it is released the film would be in the channel already but the release came in a more timely manner.
The film is soon coming so are the first dedicated ADOX Filters for it.
This is more a complete system than just a film.
We want to get people to start using filters more and expirience the creativity associated with the use.
This material (not coated by us but modified before spooling) is very well usable for this aplication even with a nice wood effect with an IR Filter similar to SFX.

With the new ADOX IR Filter (mentioned by PhotoKlassik) one can actually still shoot without a tripod, however the wood effect is not strong (just barely visible).
With a true IR Filter (in preparartion as ADOX SNAP ON) there will be a full wood effect.
We came acros this material in a search for a moderately priced raw material to be used for an alternative aplication.
It takes some modification here by us to make the film usable and it is -like mentioned above- a perfect material to experiment with filtration.

The modification process needed a tweak thus we did not release batch one and currently work on batch two.

Mirko:
Good luck with your new film.
A point of nomenclature. It isn't a "wood" effect, it is a "Wood" effect.
It has nothing to do with the product we get from trees. It is the effect that is named after the infrared photography pioneer Robert W. Wood.

Seriously? I thought it was Wilbur Wood, the knuckleball pitcher. Anyway, can't wait to try it!

Yes it is unfortunate that the Wood(person) effect is in fact the wood effect or more properly the silver foliage effect that people associate with a wood ie. trees, shrubs and foliage having deciduous leaves

Mirko the filter looks to be an innovative design. The figure, I take it, is the lens size that it fits and if you place it into the lens thread the teeth "bite" into the lens' thread so you do not have to hold it by the tab while taking the picture. Once you have finished with the filter you simply twist the filter out of the lens's thread withe tab and it can be placed in a filter holder like the flat gelatin ones

So a set of filters can easily be carried and if you want to use a polariser then your filter fits inside that and avoids any possibility of vignetting that can occur with two normal filters

Correct. The filters have been released to the market earlier.

We currently have an 85B for the Cinestillfilms, a yellow filter and the dark red/IR. We are working on "true IR", green and others.

Have you looked at "conductive" rubber compounds? They are not very conductive, but may help. There are also "anti-static" formulations. Dangling ground fibers/wires may cause scratching. This is a bit of a quandary. I am sure you will find a solution.

Not sure why hardening a steel would help. Generally hardening does not effect the modulus, only the strength.

Good luck!

Ha! These rollers are made from conductive rubber but then again you need conductive grease and this clogged up the bearings...Didn´t feel like going into these details in the video.

Understood. You got the basic idea across. Sounds like you anticipated well with the conductive covers. My first thought when you said you changed to rubber covers was "static electricity"! I have spent a lot of time on coating lines, some running films, and have worked with elastomers a bit (covers for die coating back-up rollers, 5/6-roll coaters, specialized elastomer tooling, etc.). Working with and maintaining elastomers in precision operations is a real challenge.
