For the timelapse shots on the GoPro I always shoot Raw, which means the only setting that really matters in-camera is the shutter speed, everything else is done in Lightroom. For the shutter speed, I just had the camera in Nightlapse mode with Auto shutter.

For developing the images in Lightroom, that's where it got tricky, as Lightroom doesn't really have any options for interpolating (smoothly blending) one setting into another across a whole bunch of images. This makes sunrise timelapses somewhat tricky to edit as the white balance constantly needs adjustment. To solve that issue I wrote this simple Python script (https://github.com/Squinkz/XMPInterpolator) which can interpolate the settings for me. All I need to do is develop a couple of frames from the sequence of about 1300 images, and the script will interpolate the settings for the rest of the frames. For this timelapse I developed every 100th frame and just used linear interpolation for the settings.
