Scala 50 is an excellent film where detail is needed. Rodinal 1+25 semi-stand, 10 minutes at 22C with one gentle inversion at 5 minutes develops it quite well. May need image stabilized lenses or tripod due to slow speed.
Great infrared response, with a 720nm filter I had great results rating it at 6. That's the same speed I rate Rollei Infrared 400 (Aviphot 200) at, which is much grainier with poorer quality control.
Also a great film for reversal processing, but I've only developed it as negative so far.
