A timelapse camera controller for Raspberry Pi and Canon EOS 760D (should work with any camera supported by gphoto2 with minor tweaks). Now working headlessly, i.e. without a display.
rpi-timelapse uses gphoto2 and imagemagick. To install these dependencies on your pi:
$ sudo apt-get install gphoto2
$ sudo apt-get install imagemagick
Note that if your camera requires a newer gphoto2 version to work with, you may find gphoto2-updater.sh very handful. You can find credits of gphoto2-updater.sh inside that file.
python tl.py
Here's how to post process the image frames (on Linux, can be run on the Pi itself, but faster on desktop).
for a in *; do echo $a;/opt/ImageMagick/bin/mogrify -auto-gamma $a;done
Be careful with auto-gamma - it works extremely well for sunset / sunrise but can make very dark areas of the scene very noisy.
