This is a time-lapse of a Cat 777D rebuild we shot for the local Caterpillar equipment dealer using 4 - Canon T3i's, in addition to a Canon 5D2, a Red Epic and Sony FS-100 for the real time shots. I had a laptop connected to each camera to record and save about 56,000 images per camera for the shop sequences. I used a great piece of software, GB Time-lapse, to control each camera, and control was done remotely from 300 miles away using Logmein software. The whole rebuild process took about 7 weeks. Editing was done in After Effects.
