Step 4Modifying the Exposure System
The Spectra camera was designed with one film speed in mind...that is 640 ASA. Although the technology was originated with 600 Series film, the actual film speed is 640. This is way too fast for the 100 ASA Efke I got from Freestyle Camera. Sooo you have to fool the camera into increasing its exposure. The camera has a lighten/darken slider, but this only varies the exposure by one stop. To get the exposure in the ballpark, I simply glued a neutral density filter over the light sensor.
1. Cut the appropriate neutral density filter out in a shape that covers the light sensor. I used one that would attenuate 2.7 stops (about 115 ASA).
2. Glue filter over the light sensor on the camera. I used white caisein glue so it would be easily removable if I chose to use another ASA film.
