REMOTE USB: ENABLE SYNCH: script vs builtin function

Hi all,

I saw there's a synch version of the uSB remote command option, so that when I press the trigger the cam sets itself to shoot and then shoots only when I release the button.
This is the behaviour I need.
My wonder is: is it the same if I use this built-in option or if I use a handmade script that would be something like:

while (is_pressed("remote")) do
// nothing
end

shoot()

I need this for a camera array (bullet time) prj so all shoots must be super-precisely synchronized. I was wondering which is the best method to ensure maximum synch.

Many SDM users create bullet sequences, no script is needed, the built-in functions work.

Someone is using a twelve-camera array tomorrow to photograph cars for the BBC's 'Top Gear' programme.

Synch is typically 1/5000 sec.

The twelve images are used for making stereo lenticular prints.

The same capability is available in CHDK. You might even find the new CHDK version easier to use ( as I responded to one of your other posts ) especially as I don't believe SDM is available for your SX130.

Actually, it is but has not been officially released yet for reasons mentioned elsewhere.
