this guys work is amazing, i don't have an eye like he does so my photo might not match the artistic quality.
to emulate b/w film digital is to shoot in raw, have a low percentage diffusion filter in front of lens or better yet use vintage lens. Find out what camera he uses and lenses and get that lens. his tones really aren't anything crazy different, nor does he have that much grain. Its really the scenes and the way he captured the light than the actual objective quality of the photo. But when editing look his photos as reference and study it. Add a little bit of yellow to the midtones or shadows to get some of that aged texture. but again this guys choice of light and scenery is most important imo, tons of photographers have the same tone but not as good artistic vision as he does.
i suggest using this program True Grain2 and fuck around in that, Its probably 90% exact to film
or use the method i posted on that other thread to get that grain. But other than that its simple editing of contrast.
