    Can anyone recommend any sites on the web dealing with high speed flash photography such as capturing water droplet splashes etc?

    Terry.

    Thanks for the link. The video title is a bit off putting:

    Think that just happens to be week 52 of Gavin Hoey's videos, nothing more.

    The most important factors are the flashgun, preferably off camera, set to 1/16 or less and that you light from behind either by reflecting the light off the background or through perspex (or plastic sheet).

    After that it is just a matter of focus and timing. All shots can be done without electronic triggers as per my earlier work and that of Jonah794. If you want triggers check out hiviz and a few others whose website I can't remember off-hand.

    Marky marc used that hiviz circuit and got really good results but i can't find a link to his portfolio so maybe he has left the site?

    I have just done a session in the kitchen but without the flashgun trigger but it is way too hit and miss, i got 12 good shots out of 169, i have just finished building the hiviz circuit, just got to test it now, i am hoping it will give me more consistant results 8-)

    Is it possible to use the hiviz and similar circuits to trigger the camera instead of the flashgun as in both cases you are simply closing a switch? That way you could work in broad daylight if needed, just hook the flashgun to the camera in the normal way and trigger the camera shutter which you could set to any speed desired, in some cases you may wish to use a slow shutter to include some ambient light.

    Terry,

    Yes you could the Hiviz circuit uses an SCR so basically applying a voltage to the gate allows current to flow between the other 2 terminals and all the remote plug on your camera does is short between 2 pins.

    Just check which is the ground pin on you connector and match that to the circuit.

    It would be safer to use an optoisolater to avoid any voltage being applied to your camera connector if the circuit fails in anyway.

    Also bear in mind you will get more of a delay between the trigger event and opening the shutter.

    Another way of doing it is connecting a wireless remote to your trigger - this also keeps your camera safe - but again slightly more delay (relatively) - the only complication is the combined focus/shutter release button on some models.

    Chris
