No delicker or post-processing outside of Lightroom.
Sunset to moonrise, 4 hour bulb ramp with NMX & Stage-R for panning. Variable interval 15-30 seconds.
At the 00:08 position in the video, I manually paused the Timelapse+, un-twisted the lens and let the Timelapse+ automatically shift the aperture (since at that point the bulb time was at 7 seconds). I then re-twisted the lens and un-paused the Timelapse+. It restarted, keeping the same exposure with the bulb time now at 0.5s.
I took too long to do all that, as I struggled to re-twist the lens (I had the camera tripod much too high as I was trying to reach over the chimney for the pan), so there's a jump in the motion, clouds and exposure due to that.
It will take some practice with the technique, but I think there's great potential here as a way to keep the ending ISO down while still starting with a lot of light.
I'll post a how-to video once I practice this a little more.
