Downloading files

[Waterbourn]

First thanks for putting this awesome program together. My main question is about downloading pics. In my limited time of testing with a 30 second exposure the program worked beautifully. I took out the sd card from the camera and downloaded straight to the PC. After a 30 sec exposure the program spends 30 seconds dowloading the pic to the PC before opening the shutter for the next exposure. Is there anyway to get faster downloads? Or starting next exposure while downloading? I didn't use bulb but if I do a five minute exposure then how long do those downloads take? Thanks again for your work. Going to be so nice to have this.

If should not take more than a few seconds to download the images.  Are using a USB port 1.1 or 2.0?

 

Once the image is downloaded ( a few seconds) then the image is sent to a background thread for processing and the application should take the second image while this is occurring.

 

If you post your log files I should be able to tell you more.

Does your Camera have the equivalent of Long Exposure Noise Reduction (Camera essentially takes a 1-for-1 Dark immediately after the Light exposure completes and does an in-camera Stack) ??

If so, you'll want to turn that setting OFF.

Hmm..  I will check these suggestions out.  I will break out the camera and look at that NR setting.  I can probably find those log files too.  Essentially the camera takes a 30 second exposure and then counts to 30 whiles saying "downloading".  Then the shutter opens for the next exposure.  So four 30 seconds shots takes 4 minutes (instead of just 2) for the entire process.  I thought I only had usb 2.0 ports on my laptop.  However could the cord be 1.1?  Anyway to check?

USB2 vs USB1.1 ports can be reviewed via the Device Manager.

 

A Long Exposure Noise Reduction setting would cause the same reported symptom, taking a 30sec Light Exposure and then as soon as the Shutter closes it starts a 30sec Dark Exposure. Then, as soon as that is done, it reports to BYN that the previous Exposure is completed, upon which BYN does a quick Image Download and starts the next Image.

It's a Camera Menu setting that you should check and confirm is OFF.

Yeah... this looks like NR is the cause.
