Exposure Procedures
Exposure times may vary due to thickness of transparency and the degree of contrast/saturation you desire. General guidelines for exposure are: (Sunlight) 1- 25 minutes; (Open shade) 30-60 minutes; (UV florescent) 10-20 minutes; (High intensity arc lamps) 5-15 minutes; (Mercury vapor or pulse-xenon lamps) 3-10 minutes; (500 watt photoflood or sunlamps) 20-40 minutes. Exposures onto cloth or other low-reflective surfaces: add 50% exposure time.
| 1) Take print outside into the sunlight. Print will begin
to change colors as the UV light exposes the print.
Use a stop watch to monitor exposure time. |

| 2) After 1 - 10 minutes the frame looks "solarized" indicating the end of the process. ( Note: this is very forgiving for over exposure!) |
