Tappan Zee Bridge Timelapse

Using A Long Lens For A Bridge Timelapse

This is a timelapse experiment I conducted with my friend David on the shores of Nyack, shot with a longer lens for once.

Usually timelapses are shot with wide angle lenses, presumably to better capture the expansive sky and cloud movements. But in this case since we were on the opposite shore of the Tappan Zee Bridge, I thought I’d experiment with a 120mm lens to bring the bridge construction into clearer focus.

Genie Mini Panning With Longer Lenses

I also used the Syrp genie mini to do a pan during the timelapse. However, given a zoom lens, the overall pan was only 5degrees, and I had an ease in and ease out setting of 4 seconds for the entire 13 second sequence. This clearly did not work out, the camera does not begin to pan until 4 seconds into the sequence, and the ease out did not seem to happen correctly.

So the learning for me here is that in the future I would only use a 1 second ease in and out, or skip the ease in and out setting all-together.

LRTimelapse

We once again shot this timelapse using the qDSLR Dashboard app on an Android tablet, and used the auto-holy grail sequence to adjust the exposure as the light faded. Probably should have started a little earlier and let it run a little longer, but for the sake of experimentation the overall sequence ran 40 minutes, with exposures at 7 seconds each, resulting in a 13 second long cliep at a 24fps framerate.

In the attached screenshot the yellow line with spikes illustrates where the qDSLR auto-holygrail exposure adjustments settings were placed, and where the LRTimelapse software automatically compensated for this, resulting in a pretty smooth day to night transition. One of my favorite features in LRTimelapse is the ability to “rotate” the overall adjustment sequence, causing a gradual and natural transition from light to dark. Otherwise the sequence would have stayed as bright as the first few frames, but by rotating the yellow adjustment sequence clockwise, I was able to achieve a gradual darkening in the final video.
