Now I have film, and I have it loaded into one of my brownies, time to start shooting. But wait! I know the two apertures are approximately f/11 and f/16 and I know what ISO of film I put in, but what is my shutter speed? There are some complicated ways out there to measure the "I" (instant) shutter speed on the brownie, but I am not an electrical engineer so the best I could do for now was film it with the 5dm2 at 30 fps
Doesn't really help a lot since it is only open for 1 frame so it could still be anything between 1/15 and 1/60th of a second. My best option for measuring it? Taking photos I think. But to get an idea of what it is after I have shot I need to get an idea of what light there was at the time. Of course the brownie doesn't come with a meter, . . . but my iphone does! In the form of the Light Meter app. I am really excited to try it out!
