The team from Tested, including Jamie and Adam of Mythbusters fame, all had their portraits taken by San Francisco based tinytpe photographer, Michael Shindler. Take a behind the scenes look at Jamie’s portrait session and recieive a bonus education on the entire tintype process from Shindler in this 6:30 minute episode of Tested.
According to Shindler, the ISO of his camera when shooting tintypes is about 0.5, about 7 full stops below ISO 100. With that information, you can probably imagine how much light you need to expose one of these portraits. Outdoors on a sunny day, Shindler says an exposure will take betwee 2-10 seconds. In the studio, you need to bring a lot of light to the plate (pun somewhat intended).
