And I love the happy accidents that happen when you process your own films.

I recently processed a box of old films I had been storing at room temperature for >15 years. Got some beautiful effects from the expired emulsions. Best (wackiest) results came from cross processing the old Velvia 50 medium format films.

Can you elaborate on cross processing and what effect it has?

It's usually processing in something other than the native chemistry (e.g., E6 in C41)

Yes. I used the Cinestill CS41 color developing kit, which is for color negative films. The Velvia films are (positive) slide. You get somewhat unpredictable color shifts, generally increased contrast. The age of the films added to the unpredictability because the emulsions change over time and there may have been some light leaking too.

Velvia is known for its strong colors and I was very impressed with how colorful the films were after all that time. Their longevity is probably why they still cost about $90-100 for a 5 pack of expired 120s.

Very cool. I loved Velvia...
