trichromatic 2

Compact shelving holds the science and engineering books at the Hesburgh Library at the University of Notre Dame. This is my second attempt at trychromatic photography, this time an inside shot under fluorescent lighting. 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 based on metering through the green lens using a Sekonic L-758DR. The film was developed in HC110 B. The scans were aligned in Photoshop CS5 and then channel merged to RGB. Some color correction was necessary.
