Its Internet legend that Kodak discovered new horizons with TechPan.
Kodak was reading AGFA's reparation docs after WWII, not the other way around.
Sensitizing with precious elements was quite an interesting read ;)
If you are at all concerned with tonality and flexibility under a variety of contrast conditions please do your own testing and be very skeptical of what you read. If you like what you're seeing, by all means use these films. Just be aware they are special purpose films and as such will never give you anywhere near the overall utility, flexibility and quality of general purpose films. There are always tradeoffs.
-) Rollei ATP is NOT an Aviphot film
-) I share your attitudes on Maco's attitudes...
Yes, the film is made by Agfa.
I've shot a dozen rolls of Rollei Pan 25/Rodinol and aside from a few film defects, I like it so far, probably more than Ilford Delta 100. But I just read it's being discontinued (the current emulsion is in fact Efke 25), so I'd rather try something else... I ordered a few rolls of ATP, and will soon try TMAX/Xtol...
My experience with Tech pan was limited and I mostly shot some blast furnaces in low contrast lighting and was more concerned with detail.
On another note Mike, do you know of any good drum scanning services in Montreal ? I just had a really bad experience with Photosynthèse...
Agree the best way will be to try some of these films and see what you can do with them. They will take some practice and experimentation though (as will any film/developer combo) so if you want to experiment with a few different films like ATP, CMS etc you'll have to do more than a few rolls if you want to really compare them. Particularly with these high contrast films, there are lots of ways to develop them, get different curves etc, so don't be discouraged if the first several rolls are a bust. If ATP is similar to Tech Pan it will probably be a little easier to use than CMS20.
Regarding drum scanning, I can't help you there. I'm a darkroom printer and have zero experience/knowledge when it comes to scanning - particularly high quality drum scanning. You might want to give Photo Service a call since they have a lab that does work for pro photographers. I don't know if they do drum scanning per se but they could probably point you to the right places to get it done properly.
