issue after adjusting automatic histo setup

[Opmc73]

Hi Robin,

I got an issue (send you 2 reports)
I moved the hsitogram automatic agressivity setup in the settings to 3,84 and then when I did the icon for automatic histo in live stack, it crashes immediatly sc.

Kind regards
Olivier

Hi,

thanks for the report - can you remember which type of stretch you were using in live stacking? Arcsinh or reciprocal? And if you had the soften on arcsinh or the power on reciprocal adjusted then it would be good to know those values too.

The problem is that the auto stretch is creating a negative black level, and that is now being rejected as an error when it is applied (previously it got allowed and then all sorts of stuff went subtly wrong later in the process).

I just need to find which auto stretch calculation function can produce the negative value and work out why and we should all be happy again

cheers,

Robin

of course , reciprocal

Interesting, the auto stretch for the reciprocal stretch cannot generate a negative black point, but maybe it generates a negative mid point and then moves the black point down so it is below the mid point - I will investigate

cheers,
