My timelapse workflow can be divided in three different parts: planning, actual photography, and post-processing. This is no different whether I shoot for a project of my own or for a client.
The first stage of every timelapse shoot involves careful planning and preparation. When possible I will scout the location in person, but if not there are many online tools to study the surroundings and find the best points from where to shoot. Planning also involves deciding the best time to shoot and checking out the weather and the timing of the sunrise and sunset, and getting permissions, if necessary.
Actual photography can take anything from under an hour to multiple hours, depending on the complexity of the setup and the subject. A static, single camera setup intended to capture the flow of people or cars would take less than an hour. Hyperlapses and more complex motion control setups might take a few hours. It may take as much as five or six hours to capture a full day-to-night (or vice versa) transition, which is sometimes also called the “holy grail” due to the complexities in timelapsing it. Capturing star-trails or the movement of the moon may take just as much time.
Back home, all photos are transferred to a hard drive and immediately backed up. Each clip is then processed and color-corrected in Adobe Lightroom. When necessary, clips are further edited in LRTimelapse to remove flicker, or in Adobe After Effects to stabilize hyperlapse sequences. Deliverables can take the form of stills or movie clips up to 4K.
