Which command to use for setting shutter speed / iso / aperture ? I prefer to control it from remote
The "sweet point" will change with scene illumination
I believe reyalp set the shoot() command in his multicam script to accept exposure parameters. Take a look at his source / docs ? I'm travelling now and can't do so easily from my POS mobile phone
The multicam 'shoot' function does not, but testshots does. Assuming you are using a script like multicam or bcam, you just need to send the 'call' command with lua script to set the desired parameters. See
http://chdk.wikia.com/wiki/CHDK_Scripting_Cross_Reference_PageIf you want to be able to enter more friendly units, you can refer to the code for the shoot cli command
edit:
One important thing to remember if you are setting exposure parameters using lua functions is that in general, script overrides are only applied while the script that set them is running. So if you are working with a single camera and do something like this:
=set_tv96_direct(1024)
=shoot()
The exposure will not actually be set, because each = command runs as a new script and overrides are cleared in between. Instead, you should use something like:
=set_tv96_direct(1024) shoot()
In multicam, the script is started when you use mc:start() and runs until you send the exit command, so you can use
!mc:cmdwait('call set_tv96_direct(1024)')
followed by the calls to shoot.

Corrected typo
