Smart Histogram with Mono Cameras

[poolemarkw]

I'm currently using SharpCap with a color camera but am considering getting a mono-camera. How does the Smart Histogram process change? Do you do the "dark area" measurement step with no filter, then use those same settings for all possible filters?

Thanks! Mark

Hi Mark,

good question - the dark area measurements should be done (strictly speaking) with the filter you are planning to use, since you want to measure the photons reaching the sensor from the sky background under actual imaging conditions. That being said, if you are using RGB filters then measuring with the blue (which tends to have least sensitivity and sky glow) and using the suggestions from that for all colours would probably not be far wrong. If you are using narrowband filters then you probably do need to measure the brightness for each filter individually, as they could vary quite a bit.

cheers,

Robin
