>>2627039The weird as fuck B&W conversion you posted here makes me question any advice you'd give on the matter. It looks like you just fucked up the exposure and raised the blacks and shadows as much as you could. Looks terrible.
If you want nice B&W shots simply select your favourite B&W film and filter, then find the subject and light you'd like to use it to capture.
Digital conversions to B&W may have flexibility, but it's a decision between a number of shit looking results rather than any good ones.
B&W shot with a nice negative film exposed and shot right will always trump shitty digital shots.
