Read the chart from the long end. Infrared Look renders what a converted sensor sees past visible light: chlorophyll bright to near white, a blue sky near black, water kept dark under glowing leaves. The reference is Wood Effect. Around it the set moves in one direction at a time: the sky crushed further, the foliage lifted further, the grain coarsened to a plate, the whole thing held high key for a pale winter canopy.
Then the red gel. Red Filter is the classic landscape mono: sky pushed down, warm ground and foliage lifted, ridges cut clean from the sky behind. It runs by country, chalk and limestone, moor in flower, farmland, conifer stands, marsh and reed, drystone wall. Distance haze is cut through with the blue held heavy.
The sheet is filed in four rows: infrared led by foliage, infrared led by sky, red filter over open country, red filter in woodland and water. Colour goes in; a filtered negative comes out.
