Prototype Design
The first steps
In the beginning we wanted to test, if it could really work to photograph fluorescence with an smartphone. Therefore we got an light engineering Filter from the "Frauenkulturzentrum Bielefeld e.V." and put it in front of the camera and the flash. You can see different colors in the picture. So in our first impression we thought it's worth to try some other Filters.
Therefore we bought a lee color filter catalog and began to test different filter combinations. But before testing we decided to messure the extinction and emission spektra from sfGFP as a basis to choose the most promising filter combinition. It was possible to make such a preselection because every Filter had a light transmitting spektra.
The next step was to create an dark environment. Therefore we did handicrafts to design a "black box". Now it was possible to take photos under same conditions and same background.
The filter combinitions
The groundwork is done. Now we had to find the ideal Filterkombination. So we made a lot of photos with the preselection in every combinition. After analyzing the photos with Fiji. The optimal filter combination was tokyo blue in front of the flash and twickenham green in front of the camera.
