Here's what I have:

Self inflicted ‘test assignment’. Testing various film, pushing, pulling, etc… whilst trying to get respectable, calculated photos.

I am taking photos of children at a childcare centre (inside and outside) and to cover a bit of ground would like to experiment with various films and settings.

Film that I currently have at my disposal are:
35mm Kodak Professional BW400CN
35mm Fujicolor NPC 160
120mm Kodak Professional T400CN
120mm Tri-X 400
120mm Ilford XP2 400
120mm Fujicolor NPC 160

Question: How best do I best record for testing film at various speeds/settings? Is there a 'methodical way' of testing?

Thanks everyone!
Kind regards
Nicole
