What should I look for in a digital camera for hobby usage?

Ott's initial "day-job" career was that of a banker, with time-lapse movie photography, mostly of plants, initially just a hobby. Starting in the 1930s, Ott bought and built more and more time-lapse equipment, eventually building a large greenhouse full of plants, cameras, and even self-built automated electric motion control systems for moving the cameras to follow the growth of plants as they developed. He even time-lapsed his entire greenhouse of plants and cameras as they all worked, a virtual symphony of time-lapse movement. His work was featured on an episode of the request TV show, You Asked For It in the late 1950s.
