From last night...
I used a Nikon F2 with a 1.2 Nikkor lens shot at f/2
Film was Ilford FP4 125
I had the camera on a tripod with no tracking for about 40 seconds with my camera/lens and film combo.
I forgot my timer, so counted one hippopotamus, two hippopotami,
three hippopotami..etc. etc. up to 40 hippos to time my photo. Sounds
silly...but it works for me, plus I have a tendency to count slow so I
have an added reciprocity factor built in.
Anyway, I snipped out the exposed frames in a dark bag this morning
and then developed the film in Arista Premium 1+9 for about 5.5 mins.
