Shooting dark weddings
I thought that attached images would have shown up with the post link. There are three there that I made while photographing a protest meeting. I used Pentax 645, 75mm f/2.8, at 1/2 second.
The thing with fast films is that they will always be grainy, and it's just a matter of what type of grain. I noticed that you prefer 120. What type of MF camera are you using?
