Hello everyone,
I’d like to take a few IR photos in the distant future (when the sun is shining again and the grass and leaves on the trees are green once more).
As is well known, the Wood effect isn’t particularly strong with the film mentioned above, as it stops at 720 nm.
But it’s certainly enough for ‘playing around and testing’.
I have a 720 nm filter.
Does anyone have any experience with these films?
I’d like to know a bit about the development time, or rather how the development process compares to developing 200 ASA film (Adonal & Xtol).
What ISO setting on the camera gives reasonable results and a nice effect?
Best regards, Oliver

My latest enquiry to Maco revealed that the Rollei Retro 400S is the same film as the Superpan 200.
Quote from Mr Barth at Maco:
[font=Verdana][size=2]The Retro 400S has always contained AVIPAN 200, which Agfa Gevaert cut for us into 35mm and 61.5mm rolls. We used the same film for the Superpan 200.[/size][size=2]
[font="Verdana"]Why? Because at the time, we launched the Superpan 200 as an alternative to the Agfa Scala 200 in the reversal process. Stocks of Agfa Scala are finite and cannot be reproduced. We offer the Retro 400S as a ‘standard’ panchromatic film.[/size]
[size=2]
[font=Verdana][size=2]What still doesn’t make sense to me personally, though, is why Maco has the Avipan 400 data sheet on its website if the Retro 400S isn’t actually that film, and why there’s a price difference between these two films, given that they’re obviously one and the same.[/size][/size][size=2]
[font=Verdana][size=2]For my part, I’ve become extremely sceptical about Rollei films.[/size][/size]

Well... the Retro 400S seems to have been the Avipan 400 / ASP 400. At least, that’s what a certain Hartmuth Schröder claims on the aphog forum...

So, with the Retro 400S and the Infrarot 400S, two films based on the AviPan 400 were offered.

...'based on...' could mean anything (or nothing at all)!
Maco was/is quite creative in that regard...

Hello everyone,
No offence, but I didn’t want to know which films are identical!
It’s well known that Maco likes to be extremely creative, changing film suppliers or emulsions without updating the data sheets.
Unfortunately, that misses the point of the topic or question!
I asked about the use of the films mentioned above for IR photography, specifically regarding the adjusted development (development time in relation to 200 ASA exposure and development) and the ASA/DIN setting for TTL metering with a 720 nm filter.
I’d love to see some sample images and, ideally, hear about personal experiences.
Best regards, Oliver

Hi Oliver,
You can forget about TTL metering with an IR filter. The only solution is to use an external light meter (or shoot without a filter) and adjust the film speed. Depending on cloud cover and the position of the sun, I’d set it to around 12 to 25 ISO with this film. The best thing to do is to take a series of exposures and make notes about them. That way, you’ll have a reference later on as to which setting worked best in which situation.
The development then proceeds as usual; the film will have been correctly exposed, taking the filter factor into account.

Hello,
So if the film was exposed at 12 ASA with a 720 filter, is it developed for exactly the same length of time as if it had been exposed at 200 ASA without a filter?
Best regards, Oliver

My experience with the SP 200 and 720 filters: experience 3–4 stops of overexposure compared to the standard reading. On sunny days, this puts you in the range of 1/30 s at f/5.6–f/8.

...the Superpan 200 is well suited to IR photography. Using a Hoya R72 filter, I set the ISO to 25 and perform the development of the film in A49 according to the instructions. Incidentally, the easiest way to take IR shots is with a viewfinder camera – because with an SLR and the IR filter attached, it becomes rather impractical when it comes to focusing and composing the shot...
The Superpan is an unproblematic film that I also really like in ‘normal use’ – with one exception: I haven’t yet managed to carry out the development of a single roll of film in Rollei RHS that was usable... I have tested and found A49, D76 and – if you like staining developers – Märsch Tanol Speed to be ‘good’.

Hello everyone,
Thank you very much!

Yes, the Superpan 200 performs quite well in Atomal; it actually has a sensitivity of almost 200 ISO during exposure without a filter. In terms of look, it’s a bit like the Foma 200, but it has higher contrast.

I tested the Superpan 200 / ASP 400S / Retro 400S in Adonal/Rodinal.
I used a 1+25 ratio, developed for 6 minutes and 30 seconds at 20°C. I gave it a 30-second continuous agitation, then gently agitated it twice every 30 seconds.
The film comes out at 160 ASA / 23 DIN and has a mean gamma of 0.74.
In zones 3 to 7, the film is slightly below the ideal curve, and from zone 7 onwards it steepens.
Zone 8: 1.65
Zone 9: 2.21
Zone 10: 2.58
At 7:00 minutes, it sits on the ideal line from Zone 1 to 6.0, then it rises sharply! gamma 0.81
A roll of film is already hanging on the line to dry for 1+50.
Xtol 1+2 will be done next week. I’m following Jörg Bergs’ values for that.
However, I’ve had quite good results with stand development, with film exposed at 800–1600 ASA.
500ml water + 3ml Adonal + 50ml Xtol. 18°C.
30 sec. continuous agitation, gently agitate 5 times every 30 minutes. Total time 120 minutes.
Low grain, sharpness, prints in grade 2 and scanning are no problem.
Best regards, Oliver

Hi Oliver,
Give the film thorough and generous exposure, and it’ll turn out fine. Go for Kodak!
By the way, the XTOL instructions are now available here:

That’s quite strong. You wouldn’t want to use it for portraits.

That’s been my experience too. Of all the developers I’ve tried, A49 mitigates this effect best.

Hello everyone,
The development times for the ASP 400S in Rodinal 1+50 are ready.
Rodinal / Adonal 1+50 at 20°C: agitate for 30 seconds, then gently agitate twice every 30 seconds.
10 minutes 30 seconds
The curve is slightly below the ideal line from Zone 1 to 7, then rises from Zone 7 onwards.
Zone 4: 0.40
Zone 5: 0.55
Zone 6: 0.76
Zone 7: 1.10
Zone 8: 1.50
Zone 9: 1.90
Zone 10: 2.20
125 ASA / 22 DIN - gamma 0.73

EDIT: ASA / DIN values and gamma changed!

Hi Oliver,
Thanks for sharing your test results.

Zone 1 - Zone 8 below the standard line; from Zone 8 slightly above the standard line
Zone 2: 0.12
Zone 3: 0.26
