adjusting the power (index) and the use of all-optical half size shooting outside, what are the 5 functions?I don't know much about the role of flash photography lights, thank you
3 shape light lamp full / half open button4 shape light switch button5 photosensitive remote control (synchronous) buttonThese things about it, does not affect the shooting, of course there are other light to help observe lighting effect.
I see every flash above has at least 4 buttons, in addition to the power button and half all outside, the other two didn't know!Chasing the answerThose things are human nature, and the more careful you are, the more useful it will be to the photographer's work, not too important.Usually 4-5 buttons:1 flash test button, to see if the lights can flash2 modeling light sync button, open, the molding light is bright at any time, off, then flash when the form closed
In fact, these are the main, and there will be no function, because indoor flash, relative to the set top flash is large, the purpose is to let people use light, light control, serious photography. You don't need TTL at all. The design inside doesn't need too many automatic functions to interfere, because you can adjust the output level, and then you can control the distance of lights artificially. Other functions, such as modeling light lamps, are actually supplementary. If you want to know, you can go to the local material market lighting shop to have a taste.
