Medium format Lomochrome Purple around Ball State Campus and at the KY Renaissance Fair, from my Decora ii camera that was made around 1954; feels very fun to make such photos full of whimsy on a 70-year-old camera because, for my oldest camera, it takes a hell of a clean photo.
With these 100-400 variable iso films from Lomography, I usually stick to a seemingly safe 200 on my light meter and go from there.
