gphoto2 based focus bracketing tool
With focus bracketing, a sequence of camera images with a focus shift is generated. These images can then be combined into a single image with a wider focus range.
sudo apt install gphoto2 hugin-tools enfuse
pip install -r requirements.txt
(1) Connect your camera via USB
(2) Test your connection
gphoto2 --summary
This should print some information about your camera.
(3) Obtain a sequence of images with a focus shift (focus bracketing)
python bracketing_runner.py -o OUT_DIR
This will capture a sequence of images and download them to OUT_DIR
(4) Align the images - optional (image alignment)
align_image_stack -m -v -a ./OUT_DIR*.JPG
(5) Combine the images (focus stacking)
enfuse --exposure-weight=0 --saturation-weight=0 --contrast-weight=1 --hard-mask --gray-projector=l-star -o stacked.tif ./OUT_DIR/*.JPG
If you didn't skip (4), then you might need to adjust './OUT_DIR/*.JPG'

python bracketing_runner.py --help
