These were mainly shot at f/4 although Leica digital cameras cannot record aperture as there is no data link between the lens and the body. I quite like the B&W preset profiles in Rawtherapee - there are 4 to choose from. 1/125s, iso160 1/250s, iso160 1/250s, iso640 1/180s, iso320 1/125s, iso160 1/250s, iso160 1/250s, iso160 1/360s, iso160 1/750s, iso160 1/180s, iso160 1/250s, iso640 1/180s, iso320
