Three views of the same place, two cameras and two films:
First the Fuji GW690III with Kodak T-MAX 400 (no contrast filter):
The lens for this camera is known for it's higher contrast.......especially in the rocks, but not so much for the sky. No filter used.
Now the Mamiya-7 with Ilford SFX-200:
The dark sky is a tell tales characteristic of IR-sensitive films like SFX-200. Using a 695 IR filter to allow some visible light through..........
And a second Mamiya-7 with Kodak T-MAX 400:
Much less contrast in the rocks than the Fuji GW690III; less darkening of the sky than SFX-200; using a dark red filter.
