MGD Whichever films you are experimenting with. I know very little about Medium or large format because I have never shot either of them. But I love to experiment with film and love to look at the different results. Having shot 35mm most of my life, I have experimented with many different films. Right now I have a few different rolls of film to experiment with. Last time I went to the camera shop I picked a roll of Ilford B & W, and a Roll of the Kodak c41 process. So I could compare the two. I also picked up a roll of the Kodak professional film, and a roll of their high definition. I have used kodaks High definition film before and loved the color saturation in it, one of the best I have found. I also picked up from the bargain bin A couple of rolls of Mitsubishi film, never heard of it before, at a dollar a roll, I couldn't resist. I have also done the same thing with Fuji. The only Fuji film that impressed me was their Fujichrome. It litterally blew Kodaks Kodachrome away. On two different occasions (buying from two different vendors) Fuji superia disappointed me, as did the Kodak gold. I just like to experiement and compare results! So it would be fun to compare the different films that you use in your medium format. Brenda :)
