HDR Timelapse – Las Vegas

Today I edited the HDR Timelapse sequence of the Las Vegas sunset.  I had shown one frame from the sequence over the weekend and posted a larger version previously as well.  This is one single tonemapped edit from the HDR Timelapse sequence. (Video link to Vimeo below).

Today I had a real estate shoot cancel, so I got a bunch of past real estate shots edited and then took some time to piece together the Las Vegas Sunset HDR Timelapse.  Because I chose to merge to hdr and tonemap that one single image over the weekend (above) using Photomatix Pro, I thought I’d use Photomatix Pro again for the entire sequence.  What the hell.  Its not for a client so a little over saturation won’t matter here.  I made a few mental mistakes in the pipeline because I generally use other apps, but the results are O.K. for government work  :)

This was the capture/post flow:

Nikon D3  + Nikon 85mm f/1.4D shot through my hotel window on a tripod utilizing the in camera HDR Timelapse (You can combine a timelapse with bracketing in the D3).  I chose to go with a 7AEB with 1EV steps and the camera was firing off that bracket every 15 seconds.  Of the 7AEB I killed off the final over exposed image of each bracket.  I felt adding that latitude would brighten the image too much.  So each merge to HDR was 6 shots spaced 1EV apart.  The total number of tonemapped shots was 90.  Basically covering a span of  22 mins 30 seconds worth of time during the sunset. Both the Merge to HDR and Tonemapping was done in the batch feature of Photomatix Pro.  I then took the tonemapped images into Final Cut Pro for time and color treatment before exporting for YouTube & Vimeo.

Because I shot this sequence in portrait mode, I opted to make slight color correction differences to two versions and post one video with both playing together.  I should have pushed on image a lot harder to show variation.  Now that I’ve watched it online it seems very subtle.

I also simultaneously shot a HDR Timelapse a foot away from the D3 with a Canon T2i in horizontal mode as wide as the kit lens will go (18mm for that EF-S, but on a crop body).  I shot for a full hour with the T2i.  About 15 minutes prior to setting up the D3 and the same after the D3 exhausted the compact flash I had in it.  It will be interesting to see those results versus the D3.

I’m no expert when it comes to compression/encoding.  I can only say that the video looks a hell of a lot better in FCP than online!
