Figure 1. Comparison of photoresponses of rods and cones to a series of flashes of various intensities. Flash duration: 2 ms, wavelength: 519 nm. Upward triangles mark the moment of the flash. A: Frog red rod. Intensities: 0.19, 0.48, 1.2, 4.2, 10.6, and 260 photons·μm−2 per flash. B: Red-sensitive Carassius cone. Intensities: 865, 2,170, 5,450, 13,700, 34,400, and 300,000 photons·μm−2 per flash. C: Green-sensitive Carassius cone. Intensities: 1,370, 3,440, 8,650, 21,700, 75,300, 189,000, 475,000, and 2,370,000 photons·μm−2 per flash.
