Section III Introduction
A thorough understanding of photography is crucial to successful nightscape imaging. This section covers all the information you need to know. We start with the basics of light and the human vision system. We then review the key features of camera and lens systems. We explore the foundations of photographic exposure, and what the different camera settings accomplish: ISO, aperture, and shutter speed. We then discuss light painting and light drawing techniques for creative nightscape images and conclude with a brief introduction to nightscape time-lapses.
