B&W contrast filter - using yellow all the time

... How do you do that, anyhow?

By multiplying the spectral sensitivity data of all individual components (light source, filter, lens, film).

My Horizon panoramic camera came with some clip in filters, one of which is a yellow green filter. The others were a ND filter and a red filter, this was 1994.

The success of the yellow green filter made me purchase a yellow green filter for general-purpose photography. I hardly ever use either a yellow or a green filter on it's own.

Generally though I have found with current FP4+ and HP5+, the yellow green is best, with older TMax (1989 vintage) the yellow alone seems best.

All observations by trial and error on my part and B&W prints used for evaluation.

If I wish for a contrast kick, or to lighten brickwork, I switch to an orange.
