Help! Superpan 400 film??

[mfohl]

Hello Folks, I have four rolls of a "Superpan 400" film to develop for a client, and I can't find any processing information. From the packaging and the name, it appears to be a Rollei film. It has "RR4025" on the label. Massive Dev Chart lists info for Superpan 200, but not Superpan 400. I googled it and found some Rollei films at a mail order place in England, but didn't see any pictures of Superpan 400.

Does anybody have any idea how I would develop that? Times for Superpan 200 seem to be longish. Should times for Superpan 400 be longer-ish?

Thanks in advance,

-- Mark

I can only offer that my method for developing unknown film is to take a clip, expose it to full light and with use of a paper clip or such device, lower the film into the developer in small sections 2 minutes apart, say from 4 minutes to 12...

Then after fixing, hold it up to light and the darkest section that barely transmits any light is my development time.

There are probably better ways.

well, this film is aviphot 400, made by Agfa rebranded by Rollei. For the aviphot 80 I have been using a semi-stand development in pyro-cat HD. my personal experience is these films loose a full stop in speed, so over-expose your negs. BUT you need to compress your highlights with minimal agitation and use a soft working developer. for the aviphot 80 I develop in pyro-cat HD @ 1:1: 200 at 68 degrees. for 25.5 minutes, agitate for first minute then two inversions every 8 minutes after that. MY advise is buy 3 or 4 rolls to experiment with before processing your friends film> it is SOOOOO SOOOOO EASY TO BLOW OUT HIGHLIGHTS WITH THIS FILM WHEN PROCESSING!!!!!!!!!!!!!!!!

Sold as universal films they aren't. Aerial film require some type of special treatment to rescue the highlights.
