Last night I set up my camera (Canon 6D) to be controlled by qDslrDashboard using my Windows 10 PC. The two were connected by a USB cable. I started imaging at sunset (5:35pm) and continued for two hours. By then the sky was very dark since the sun was about 26 degrees below the horizon. I was surprised to see that about 1/3 of the images were overexposed... like a daylight shot with stars! I took the 650+ images into LRTimelapse to review how the ramping looked. and found what is shown in the attached screenshot. I thought I had activated the auto NTC but obviously, that did not work. I did not see any error messages.
I am wondering what is happening here. The program works fine until about civil twilight (sun below 6 degrees) and then starts to overcompensate for the darkening skies. I think just using the AV mode in my Canon would have yielded a better result at least up until civil twilight.
Of course, the problem with AV mode is that it won't work well when the sky gets dark and qDslrDashboard does provide a platform to manually adjust the exposure as the sky darkens. Is that what must be done when using a PC with qDslrDashboard (i.e., manually adjust the exposure when the sky becomes dark)? If so it would be useful to see the trend shown in the attachment while monitoring the exposures. Is there a way of doing that in qDslrDashboard?
