Transition from day to night: manual night exposure time does not apply but last day exposure time

[vnawrath12159]

Dear developers,

I recently updated (installed) Version 0.8 of this great software package. My setting for capture is as follows:

• Day Capture: auto-exposure = yes
• Night Capture: auto-exposure = no / manual setting = 6 seconds
• Night Capture: auto-gain = yes

I noticed, that when changing from day to night capture, the software doesn't take the nightly auto-exposure manuell setting (6 seconds). Instead it repeats to apply the last exposure time from the day capture. Auto-gain for night is used correctly.

In my opinion, there is a typo in capture.ccp in line 1866:

Instead of
if (numExposures == 0 || **asiDayAutoExposure** == ASI_FALSE)
it should be
if (numExposures == 0 || **asiNightAutoExposure** == ASI_FALSE)

This evening, I will check, whether my manual code change leads to the expected correct change in the exposure time.

Code section for switching to nighttime with the according IF instruction at the end:
` {
sprintf(textBuffer, "==========\n=== Starting nighttime capture ===\n==========\n");
displayDebugText(textBuffer, 0);

        // Setup the night time capture parameters
        if (asiNightAutoExposure == 1)
        {
            currentAutoExposure = ASI_TRUE;
            setControl(CamNum, ASI_AUTO_MAX_EXP, asiNightMaxExposure, ASI_FALSE);
            printf("Saving auto exposed night images with delay of %'d ms (%d sec)\n\n", nightDelay, nightDelay / MS_IN_SEC);
        }
        else
        {
            currentAutoExposure = ASI_FALSE;
            printf("Saving %ds manual exposure night images with delay of %'d ms (%d sec)\n\n", (int)round(currentExposure / US_IN_SEC), nightDelay, nightDelay / MS_IN_SEC);
        }

        currentBrightness = asiNightBrightness;
        currentDelay = nightDelay;
        currentBin = nightBin;
        if (numExposures == 0 || asiDayAutoExposure == ASI_FALSE)
        {
         	currentExposure = asiNightExposure;
        }

I believe you are correct. I probably did a copy/paste from the night-to-day code but didn't change it correctly.
Were you able to change it and see if it worked better?

Yes, after two evenings, the code change worked correctly. The manual night exposure value is now taken when switching from day to night.
