- A yellow photographic filter. Without it, photographing fluorescence is impossible. A yellow filter, filters out all light coming to the sensor except yellow. A well-chosen yellow filter will also allow some orange and red light to pass through. That’s not its main function, mind you, but rather a side effect.

- Fluorescent calcium sensors are widely used to image neural activity. Using structure-based mutagenesis and neuron-based screening, we developed a family of ultra-sensitive protein calcium sensors (GCaMP6) that outperformed other sensors in cultured neurons and in zebrafish, flies, and mice in vivo. In layer 2/3 pyramidal neurons of the mouse visual …

Fluorescent Mineral Photography - A How-To Guide
- https://www.naturesrainbows.com/photography
- For my typical shot I set my iso to 100, my aperture to f11. I use bright UV lamps positioned a moderate distance from my subject. My shots vary from 1 second (for very bright sodalite, willemite, esperite) to 8 seconds for most average minerals (calcite, fluorite, etc).

- Next I switch to manual (M) exposure mode, set the exposure (usually somewhere about f8 and 10-20 seconds) and set iso to 200. Then I turn the UV light on and switch off the normal lights, hold the UV lamp in proper position and take the picture. I usually repeat the UV photos several times with various exposures.
