Photography Stack Exchange is a question and answer site for professional, enthusiast and amateur photographers. It's 100% free, no registration required.

I just got a USB digital microscope and I would like to setup a long exposure experiment (~5 minute capture). Unfortunately, I have no clue what software I need to have to set up a long exposure shot. I'm not even sure how to begin to search for such information.

I have a celestron Handheld microscope using Windows 7.

@aJhenderson, wouldn't microphotography fall under the realm of photography? I could just easily have said macrophotography instead. –  bobthejoe May 28 at 20:00
    
Could you provide the model number? 44302-A, the Deluse Handheld Digital Microscope? If so, it comes with an built-in sensor and Windows software. Or is it another Celestron product? Their support site has more info. –  B Shaw May 29 at 2:11
    
I have 44302-B. The Windows software has capture software but it doesn't allow for time exposure. –  bobthejoe May 29 at 3:56
    
So, are you asking if someone can modify their capture software? Or, are you wondering if someone has written their own interface and capture software to the microscope? If so, you may want to ask in one of the coder stackexchanges. However, if you also have an optical microscope and wanted to attach a DSLR/Mirror-less/ILC camera to capture long exposures, this is a perfectly good stackexchange for that. –  B Shaw Jun 1 at 13:51

You could take a video and extract individual frames from that. You can then blend the frames together into one long exposure (For instance, in photoshop you can use Load Files into Stack and after converting it into a smart object stack you can set the stack mode to Mean, although you'll need a powerful computer for this method).

You should probably take the video at a low FPS to minimize the time needed to merge the frames together.

There's an automatic python script which can do all of this for you - http://www.eliteraspberries.com/blog/2013/01/simulate-long-exposure-photography-with-opencv.html

Won't exactly work for my purposes. My signal to noise isn't very high so I really do need the longer exposure time. –  bobthejoe Jul 28 at 5:50
    
The mean/median blend should help pretty much eliminate any noise –  user22723 Sep 20 at 22:30
