When I got my film camera last month I was too excited to wait for a light meter and loaded some film using the in-camera meter. I THOUGHT I had loaded Fuji400h so I rated it at 200, metered off their skin and added one stop. Turns out, when I took out the film, I had actually loaded Kodak400 TriX - whoops! I thought I ruined the roll, but I sent it in anyways just to see and wasn't expecting much. They came back yesterday and I was happily surprised!
My next roll of film coming back to me is also black and white but I used a light meter - it is my first roll from the Embrace the Grain film workshop I am currently taking. I can't wait to see them!
