Flashcards in Non-Big 8 Deck (8)
What is the Ferry-Porter Law?
High frequency CFF increases linearly with the log of retinal illuminance
What is the Granit-Harper Law?
High frequency CFF increases as stimulus size increases (secondary to peripheral retina detecting flicker)
What is the Broca-Sulzer Effect?
Light flashes appear brightest when they last for 50 - 100 msec
What is the Brucke-Bartley Effect?
Flickering light will appear brighter than a constant light of the same luminance
What is the Talbot-Plateau Effect?
After the CFF threshold is breached, a flickering light and constant light of the same luminance will appear as equal brightness
What are Grassman's Laws?
1. If equal amounts of wavelength are added to two metamers, they will remain metamers
2. If luminance is changed at equal amounts for two metamers, they will remain metamers
3. If A and B are metamers, and B and C are metamers, A and C are metamers
What is the Bezold-Brucke Phenomenon?
Perception of hue changes with intensity of light
