I wanted to see how much of a difference there was when overexposing Kodak Gold 200 35mm film. So I made a video out of it. I was testing the difference between shooting at box speed (ISO 200) and ISO 100. The camera I was using in the video is a Canon EOS 3 & 16-35mm f/2.8 ii. I filmed the video with a Sony ZV-1.
Thanks for stopping by, Rob

I use a Canon FTb 35mm SLR when I shoot film, and a Kodak Brownie 35mm point-and-shoot if I want a more simple film shot. I’ve always shot box speed on the SLR. The Brownie detects the film speed you’ve loaded and figures out exposure for you. One time I did shoot a roll of 200 as a 400 in the SLR, which I didn’t realize until I had shot 18 of a 24 roll. I compared shots and I didn’t see any difference, not unless it was caught in the lab.
O/T: In BC, I assume you moved from Calgary. Last week, I received a call from BC. I said to myself, “I don’t know anyone living in BC.” I guess I do now. I hope it wasn’t you calling, saying you moved to BC, LOL. 🙂
Haha yes I did move, but sadly no it wasn’t me calling. I should call more often though shouldn’t I? ;). . . But ya as for the film. I found very minimal difference when shooting from ISO 200 to 100 unless your doing long exposures. I definitely like the box speed pictures better. . . Drop me a line if your ever in Kelowna. 🙂
