Hi
I have tried with different pulse setting for flash like 50 and 100 etc but there is no change in image exposure. amount of Light remains the same. what impact is expected when we change flash pulse value?
The flash trigger pulse time is the time the flash trigger signal is active. It is not the flash pulse. This is available to allow for old cameras. When I first started developing the dropController the camera I was using required a fairly long trigger pule to activate the shutter. Since I added the facility for the camera I also added it for the flash.
The flash pulse has to be set manually on your flash; 1/32, 1/64, 1/128, etc. The longer the flash pulse (smaller numbers) the more light you get but you also get more movement in the water and so you also get more blur.
