Jim, Settings are TTL, Red, Green, & no color (full manual). You know how TTL works...camera circuit controls flash. There is an 'in camera' sensor that measures the amount of flash light falling on the film or shutter. When it senses enough light, it tells the flash to shut off and saves all that electric energy your batteries have been whining to store in the flash's capacitor.
For cameras without TTL flash, you use manual settings. Red & Green use the electric EYE on the flash front. Flash's EYE measures the light, shuts off the flash, saving battery power again. See the red & green distance scales for approx. ranges. Also remember to set the appropriate (red/green) aperture from the scale. On the cameras using 'A' series lenses (or newer?), the AF280 will set the aperture for you. The setting to the full right is full manual, no electric EYE involved. The flash just dumps all of it's electric energy into the flash tube...and recycle time is very long. In this case, you have to know the distance to the subject and use the distance scales to determine what the proper f-stop to set your lens at. Perhaps useful, but a pain most of the time... You change distance and you must adjust the aperture.
