I use the meters in tricky light - extreme low light, macro work etc and the times when I use non 400 iso film. This is my "collection" of Gossen Luna Pro's - they are big and a bit clumsy to carry around - but the work well in low light.
I am trying out a new (to me) developer - Crawley's FX 10 which contains Kodak CD 2 (a color developing compound). First attempt was OK - except that it kept depositing "blobs" on the film. It is supposedly the finest grain you can get without a loss of speed.
Acros 100 @ 125, FX 10 for 8 min. Nikon F3HP and Micro Nikkor 105mm f4.0
