I developed it Supergrain 1+12 21°C 7'.
The results are slightly thin but quite pleasant and usable. Scanned very well, the grain is present, as I have experienced with this film before and the developer also, so somehow expected. Looks a bit like HP5.
Here some aerial images, with a standard Red filter (Olympus OM1 - 50/1.8):
Here an image without filter which shows the extreme dynamic range this film can handle with this developer combination (Always Olympus OM1 - 28/2.8).
