Startrails photography video | How it was done

Alejandro Pérez: Photography, video editing, subtitles

Startrail photography assembly of 400 photos using StarStax. The video is a screenrecording while Startax was blending the images in lighten mode (with and without comet-like mode). I have separated the image in two:

  1. The startrail
  2. The motorway and buildings.

I would have obtained an overexposed result of the motorway if I had used all pictures to blend the motorway and the buildings (as I used it to blend the startrails). That’s why I only used 15-20 significant pictures (I chose the ones with the best car light trails) to compose the lower part of the image. Then using a video editing software (like Premiere Pro) to assemble the two parts of the picture and to reverse the shots.

Gear: Canon ESO 5D Mark III + EF 16-35 f/2.8 + Tripod + automated remote control
Software: Starstax, Lightroom, Photoshop, Premiere Pro.
