Request:Would it be possible to create shutterspeed min and max settings that fall within canon's own min and max settings, like iso range settings?
I'm not sure I understand. If you are using a script, then the script can set the exposure however it wants. CHDK currently cannot change what values the Canon auto exposure uses, so if a script changes one parameter, it must control them all.
So you are saying that it is not possible to send the original, possibly capped off Tv value back with the shoot command if it is a script that is running canon's firmware to calculate shoot conditions?
press'shoot_half'repeat sleep(10) until get_shooting()if get_tv96() > my_max_tv then set_tv96_direct(my_max_tv)endclick'shoot_full'
I can also imagine that people don't want a lapse recording in daytime shooting at 1/4000 continiously because of extra curtain wear, so that is why i think a cap at shortest shutter speed would also be helpfull
ok, not possible, but...
Perhaps it doesn't work the way you expected, but it is absolutely possible to adjust exposure after canon AE. You just have to script the shot using key presses rather than shoot()
QuotePerhaps it doesn't work the way you expected, but it is absolutely possible to adjust exposure after canon AE.

function my_shoot() press'shoot_half' repeat sleep(10) until get_shooting() if get_tv96() > my_max_tv then set_tv96_direct(my_max_tv) end-- ... more exposure limits if you want click'shoot_full' -- implicitly releases half repeat sleep(10) until not get_shooting()-- you might want to add some additional hard coded delay if you really need the shot to be finished when the function returnsend
