Hi Robin,


Looks like the Log update has issues.

Hi Don,

I think that data is for real, but you wouldn't have seen it before because the resolution of the graph was lower. It's basically reflecting that the incoming data is not continuous in the first frame (particularly with 12 bit sensors or with colour balance applied in camera settings). The saw tooth should go away after 3 or 4 frames.

I will have a look next time around to see if there is a clean way to suppress this sort of thing, but it is 'harmless' as they say in the Hitchhikers Guide...

cheers,

Robin

Hi Don,

I had a quick look at this in a bit more detail, and it seems that the cause is generally the use of the colour balance in live stacking. That adjustment is reflected in the histogram, and it shuffles the signal levels around and leads to the 'sawtooth' graph when the frame count is low. The resolution of the graph was too low previously to show it (except for 8 bit data).

cheers,

Robin
