Screen capture tool to increase shutter speed

[mikenerd]

I have spb screen shot and it doesn't seem to work with the camera. i just get a black pic. Also, since I can't map it to a hard button, for some reason, it wouldn't really be a good option anyway. I searched around here and elsewhere and have not seen this topic discussed. I know the resolution would be limited to the 640x480 but it would be nice to have a "what you see is what you get" option for lower light.
