I have been doing a lot of coding for the Raspberry Pi Camera in Python and have stumbled across a problem. To change the shutter speed of the camera in Python, it is possible to use this attribute:

  shutter_speed = time in nanoseconds

The issue is the shutter speed is limited to 2 seconds according to this article: https://www.raspberrypi.org/forums/viewtopic.php?f=43&t=61445

Is there any way round this? And is there a command I can use in Python that uses seconds?

  • @exantas that person was looking to get the brightest image possible in a dark environment. From the answer I posted you will see I mention the shutter speed is limited to 2 seconds. This question is about how to increase the shutter speed beyond 2 seconds. – Darth Vader Mar 10 '16 at 08:26

    The camera's exposure is currently limited to 6s rather than 2 (see https://www.raspberrypi.org/forums/viewtopic.php?f=43&t=85856). However, shutter speed is limited by framerate so you have to set a framerate of 1/6fps in order to bump shutter speed to 6s. See http://picamera.readthedocs.org/en/release-1.10/recipes1.html#capturing-in-low-light for a recipe – Dave Jones Mar 10 '16 at 15:44
