Another new film from Rollei - Superpan 200

[dwross]

Fram,

Welcome! I love the effect you got with the Superpan and R72. Great image. Thank you for posting it.

Pull development

- excellent results with pull processing at 100 ASA in Perceptol, Rollei RLS etc.

Hello.

Some time ago it was written that the Rollei Superpan and Ifrared have similar development times. But I could nowhere find times for pull processing with RLS. Normal RLS time (ISO 400) with the Infrared is 18 minutes.

Does anybody have some experience with this?

Yes, that's right.
I've exposed the Superpan 200 at ISO 100/21° and developed it in Rollei RLS with the time of the Rollei Infrared film for ISO 200/24°. Very good results.

Regards,
Jana

Thanks for the answer.

How about pulling the Infrared? The actually indicated time with RLS at ISO 200 is 12 minutes. Sounds like 11 minutes would be enough for ISO 100?

I think it is time for Ilford to become active and improve their Delta film programme.

What needs to be improved? Seriously. I have never found anything wrong with it.

200 lp/mm? Infrared capable?

This emulsion sounds awesome.

This film produces a crystal-clear negative and is capable of great results. It should not be overlooked, however, that grain size of IR-sensitive films will be greater than that of typical panchromatic films.

Push processing is certa¡nly an option up to 800 ISO with the right developer, e.g., in our experience:

Ultra Iso

Already tested two films up to 1600 ISO with ultra-iso. Some of the photos came out with too much contrast but overall nice grain and plenty of detail. I am enclosing one photo and a detail.

I didn't get much IR effect this time but I couldn't choose the time of day and it happened to be the worse.

It is a pleasure to scan. Really flat and clear. It won´t curve even at high room temperature (and I know well as I live in Sevilla!)

In my experience Superpan 200 in XTOL1+1 has about the same grain as Delta 400 in XTOL1+1 (compared via printing, not scanning). And the same speed.

Anyone know the keeping properties of a PET base? It would be great to get away from the problems of triacetate.

 

[Aurelien]

Which problems of triacetate?

 

[psvensson]

Which problems of triacetate?

It decomposes into acetic acid after a few decades. Storing it cold delays the onset. See http://en.wikipedia.org/wiki/Vinegar_syndrome.

Triacetate:

From a lecture by the Image Permanence Institute:

Many films in existing collections have acetate bases which chemically decompose, giving off the vinegar smell and ultimately leading to shrinkage and emulsion damage. IPI's research has shown that all cellulosic films are susceptible to deterioration. The rate of deterioration of the film base proceeds gradually until it reaches the autocatalytic point, at which time the rate rapidly increases. Temperature and humidity have a significant impact on how long it takes the film base to reach the autocatalytic point. For instance, film stored at 90° F and 70% RH will reach that point in about 10 years; at 80° and 60% RH, about 20 years; 70° and 30% RH, about 100 years. Cool or cold storage is highly desirable. For instance, the latest edition of ANSVAIIM IT9. 11 recommends a maximum temperature of 72° and 20-30% RH for black and white film.

Concerning PET:

Agfa states for their microfilms, which got the same base and similar emulsion components as the Superpan 200, a lifetime of 500 years.

The Image Permanence Institute calculated for Ilford’s Micrographic Film, a slver-dye-bleach film on a PET base, by accelerated tests a lifetime of several hundred years.

Thanks, that sounds great.

Hello,
This is my first post here.

I have tested my first roll of Superpan this morning. Tested with several filters trying to get IR effect and I was really pleased with the R72 filter. The roll was exposed rating the film ISO 200 and processed 12min at 25ºC in Infradol. I will try to push two steps next time. See examples

I need to shoot at ISO 800 so losing 4 stops with the filter will not force me to use the tripod in every situation.

Looks good, but I'd like to see how it does with a Red 25 filter, as I'm looking for a HIE replacement.

 

[fram]

Sorry but my tests with red and orange filters show very little IR effect with this film. It is no replacement for HIE, but excellent results can be obtained with R72 filters and choosing the right time of day for infrared radiations. I enclose the test photo for the Red 25.

I found wood effect starts to be detectable with an B&W 91 filter (equivalent to Kodak 29). Detectable, not impressive.
