2. Green flash - Wikipedia

   en.wikipedia.org/wiki/Green_flash

   Green flash occurs because the atmosphere causes the light from the Sun to separate, or refract, into different frequencies. Green flashes are enhanced by mirages, which increase refraction. A green flash is more likely to be seen in stable, clear air, when more of the light from the setting sun reaches the observer without being scattered.

   The stroboscopic effect visibility meter can be applied for different purposes (see IEC TR 63158 [12]): Measurement of the intrinsic stroboscopic-effect performance of lighting equipment when supplied with a stable mains voltage; Testing the effect of light regulation of lighting equipment or the effect of an external dimmer (dimmer compatibility).

8. Flashing (cinematography) - Wikipedia

   en.wikipedia.org/wiki/Flashing_(cinematography)

   The effect is produced by adding a small and even level of exposure to the entire image. Since exposure levels increase logarithmically, this tiny level of additional exposure has no practical effect on an image's mid-tones or highlights, while it shifts the darker areas of the image into the practical sensitivity range, thus allowing the darker areas of the image to show visual detail rather ...
