Michigan Central trichromatic
Michigan Central Railroad station at Niles, MI. This restored station is now used by Amtrak.
This trichromatic photo is the result of taking 3 sucessive exposures through RGB filters. Color artefacts result from moving objects such as the flag and the clouds. I used Tri-X 320 4x5 film in the Graflex Speed Graphic with the 127mm Ektar lens. Three successive photos were taken using a red Wratren 25 filter, a green
Wratten 58 filter and a blue Wratten 47B filter. The exposure time was 4 seconds at f/5.6. The film was developed in HC110 B. The scanns were aligned in Photoshop CS5 and then channel merged to RGB. Some color correction was necessary.
