Time Lapse, or Intervalve, refers to firing a camera's shutter at regular intervals across a predefined time period. Timelord takes this concept a step further and allows you to control multiple aspects of the camera at regular intervals.
For each item you wish to control you must create a 'Pulse'. A Pulse can only corresponds to one item of the camera (ie shutter, ISO, Aperture etc) and governs how and when it is adjusted.
For example: You may want to take a sequence of photographs of a subject with gradually decreasing depth of field. To do this you would simply create one pulse to control the shutter and a second pulse to control the aperture - note: the simplest way to achieve this would be to set the camera to "Aperture Priority (A)" as this will force the camera to set the shutter speed automatically. Alternatively, you could create a third pulse to control the shutter...
