Sooo... I shot a test roll to see what the characteristic curve looks like. It's looking an awful lot like Fomapan 100.
The green line is Fomapan 100, the blue line is Kosmo Photo Mono, the black like is the standard ISO 0.62 contrast tone curve.
Across the bottom is an 18% grey card exposed with a studio strobe and metered with an incident light meter in full stop increments +-0.1 stop through a transmission stop rated lens. 0.0 is correct exposure, then over and under in full stop increments.
Up and down the left side is the average raw ADC value of a sample 1000x1000 pixels out of the center of the frame.
It's not scientific, but it's as accurate as I have access to equipment, and is accurate enough to show that the two curves are shockingly close given that neither roll was shot at the same time, neither was developed at the same time, or scanned at the same time. If it were Foma air 100 I'd expect a significantly more dramatic S-Curve shape much like what you see with JCH StreetPan, which looks *very* S-curvy relative to pretty much anything else you compare it to, whereas this has an ever so slight rolloff on the shadows before the FB+F, and an ever so slight more density in the highlights with a slightly more rounded roll off than Fomapan 100. It's so close I'd attribute it to process variations and well inside the noise limits.
So there you have it. Not to bag on Kosmo Foto, there's nothing wrong with re-branding or re-labeling as Foma is pretty much the re-label king and readily supplies film for private labels, and it allows Kosmo Foto to provide a way to support the site if you're inclined. So with that, mad respect there, but if you want to develop it, treat it like Fomapan 100.
