I have a PowerShot A490 camera. CHDK works FLAWLESSLY on it and I love it.
There's one feature I really wish was there. Right now, if I want to take 100 photos of the night sky I need to either do them separately or hold the shutter button. I wish there was a way to hit the button once and then simply let the camera do it's job until either:
A) It reaches the requested number (for example, 100 photos);
B) SD card is filled up;
C) Battery pack is dead.
How hard will it be to make this feature in CHDK?
