Hello,
In order to characterize my CCD (bias, read noise) I'd like to take a zero second exposure.
When trying to shoot with the camera (manually pressing button with my hands)
In Extra Photo Operations I've set:
Disable Overrides [Disable]
Override Shutter Speed [0 ]
Value Factor [off]
Shutterspeed enum type [Factor]
I must be confused about something because it seems this should override the shutter speed with 0 seconds. Though I know the range of shutter speeds is dependent of the camera. Does anyone know what is the range of available shutter speeds for a A470
using CHDKptp
I'm using
con> shoot -tv=0.0 -raw=1
but this produces images with 1/48.6 sec exposures for some reason, according to meta data read by drcaw -i -v
filenameI'm using
canon a470 1.02c
chdk 1.1.0 2870
chdkptp-r330-linux_x86_64
ubuntu 12.10
Thanks for any help you can give,
