FRS3410. Jenne, Jim, Carlos, Dave
Jenne found that certain digital cameras were not snapshotting correctly. After power cycling the digital video servers and the ITMX spool camera, we tracked the problem down to the "Frame Type" setting in the digital video configuration file. The cameras which fail their tiff snapshotting have this setting set to "Mono12", those which work have "Mono8"
In fact the majority of cameras are set to "Mono8", listing is below.
Question to the digital video experts, what does this setting mean and what have we broken by reverting back to "Mono8"?

A few months ago, Kiwamu and I set some of the images to mono12, because 12 bit images have a slightly better SNR than the 8 bit images. We can switch them all back to mono8, except for the green ITM cameras, which we use for beam position refercences. It might be better if we didn't change those settings (ie keep the ITM green cameras set to mono 12.)
Fewer programs will open the 12 bit images than 8 bit images, but you can open them in python or matlab. Attached is a matlab script for opening the mono12 images, for them what don't want to write their own.
