Film Evaluations

Methodology

I’ve written a detailed account of my methodology here. I created an idealized digital test target with zones from (roughly) 0 to X, in one-step increments. I then meter on Zone V with a Pentax Spotmeter V, and shoot several frames both under- and over-exposed for the indicated exposure index.


Ilford FP4 plus 125

Summary

Easily my favorite film, FP4 plus shows very fine grain, good contrast, and a lot of latitude. It also pushes well up to at least ISO 500.

Push/Pull: +2 (ISO 500)

AgfaPhoto APX400

Summary

I am reasonably sure that given my development technique, I can easily rate this film at ISO 800 without additional development time. Full review: part 1, part 2.

Push/Pull: 0 (ISO 400)

Test Targets


Kodak Double-X (5222)

Summary

Nominally an ISO 250 film, Kodak informs us it can be shot from ISO 50 to 1600 with suitable adjustment in development. Initial experiments reveal that I would rate this film at ISO 500 with normal development. It shows good tonal separation in the midtones at this speed with lots of room for shadow detail, though shadows are notably grainy compared to other films.

Push/Pull: 0 (ISO 250)

Developer: Adox XT-3
