12 of 50 from July 2018

This is 334 images, one taken every 16 seconds (mistake #1). The exposure started at 1/4 of a second at f20 and ended at 15 seconds at f3.2. Shot ISO 100 the whole time. I missed 6 images because the exposure went from 15 seconds to 20 seconds so when it tried to reshoot 16 seconds later, it was still taking the previous image.

I had to change the exposure. I did that on the command line using lines from a spread sheet like exiftool -Exposure2012=-0.43 DSC_09999.dng .

The images are turned into a video on the command line using:

ffmpeg -framerate 15 -pattern_type glob -i 'DSC*.jpg' -c:v libx264 -filter "minterpolate='mi_mode=blend:fps=30'" -profile:v high -level 4.2 -pix_fmt yuv420p out_compat31.mp4
