Been wrestling with Rollei 400 IR for a while and I think I've found a EI and development scheme that gives me proper shadow detail without too much blown/harsh highlights.
This was taken in a low-angle autumn evening, self portrait using the infamous Autoknips III ^^
Basically, I exposed the film more and pulled the development 1 stop from what I usually would do. Negs look normal, no problem getting details in either shadows or highlights from scans, have yet to mess around with it in the dark :)
