Rollei Ortho 25 vs Kodak HIE Infrared

The two ends of the spectrum.

The same photograph, same exposure, both looks at full strength. See the untouched original.

The difference

These are the extremes of spectral response. Ortho 25 is blind to red, so lips, skin and anything warm render dark — the way every photograph looked before panchromatic film arrived. HIE sees past red into infrared, so foliage glows white, skies go near-black and highlights bleed with a halo. Neither is a stylistic filter; both reproduce what the emulsion could physically see.

Which to use

Period looks, still life, dark skin and lips, graphic contrast.
