Is there a bulb feature included?
Quote from: rocket187um on 19 / December / 2011, 14:58:50Is there a bulb feature included?If I understand the definition of "bulb" correctly, you want to be able to open the shutter with the press of the shutter button and have it stay open until you release that button ?So far as I know, its not possible to control the shutter directly with CHDK. But you can set quite long shutter speeds so the lens stays open a long time. This is lame but I guess you could try that and then place a dark card in front of the lens when you wished to cut off the exposure manually ?
Easy enough to write a 'bulb' script
- but it would have to use another button to activate and then close the shutter since the shutter button will start / stop the script.

Or maybe start and then cancel a long exposure on the fly?Quote - but it would have to use another button to activate and then close the shutter since the shutter button will start / stop the script.Might be best to use the USB remote here anyway - so as not to jiggle the camera during the exposure.
press "shoot_half"press "shoot_full"...code to wait for another button or remote...release "shoot_full"release "shoot_half"
press "shoot_half"press "shoot_full"
Maybe I'm being a bit thick, but Code: [Select]press "shoot_half"press "shoot_full" just does the same thing as pushing the shutter button manually and holding it down. The camera takes a picture at the current exposure and ISO setting. It doesn't hold the shutter open while the button is pressed
