Get histogram values for Astrophotography
« on: March 20, 2017, 11:01:59 AM »
Hi, all.
First of all i wanna say tanks to all community of ML. your firmware rock!

I am new in astrophotography and sometime I got wrong pictures because I over exposure the subs. So, to take good subs in astrophotography, the luminosity histogram should be placed 1/4-1/3rd from the left (range 0 to 255). How can I get the mean and dev.St value of the luminosity peak?

thanks for your suggestion

That is a great idea, I think a RAW image statistics function would be great.  Mean, median, std deviation, MAD would all be superb for astrophotography and other scientific applications.

Is this request something raw_diag doesn't do already?
