Charlie:
Rollei TLR instructions for Orange and Red filters
says:"_For use with panchromatic emulsions only_" ; the entire
paragraph says: "Orange and red filters render yellow-red and red
brighter and green and blue darker. A deeper filter enhances this
effect. For landscapes: to produce dark to black skies, simulated
night effects. Further advantage: absortion of blue distance haze,
renders landscape detail with greater brilliance and higher contrast.
Full UV filter effect. For use with panchromatic emulsions only".
This is a sample I took with the Rolleiflex 2.8C, Rollei BIII light
red filter, Agfa APX 100 developed in Rodinal 1+25:
