Stack - Histogram - Color curves

#1

Post by roelb »

Version 3.2.5958.0
Using ZWO ASI224MC
In the stack window: when I alter the color bars height at the right of the histogram the color graphs don't translate.
I want to center the color curves above the white curve to obtain a natural color.
Also the automatic color adjustment alter the color curves.
In the small histogram (no stack) changes can be made with the Red and Blue sliders.

Red and blue sliders in the image control section on the right hand side will change the signal at the camera source and thus effect the large histogram in live stacking. The red green and blue vertical sliders in the live stack histogram window are post processing controls. You'll see the effect of changing these controls in the small display histogram.

Auto color affect the camera source signal it basically move the red and blue sliders in image control.
I want to center the color curves above the white curve to obtain a natural color.
You want to white balance your image. I recommend leaving the red and blue sliders in image controls at 50 / 50 and adjust the colors with the live stack histogram controls

see this thread viewtopic.php?f=5&t=1282 on page 5 I describe the process I've had much success with.
