Depth perception is a basic ability of human vision. It is through depth that we judge distances and spatial relations. But depth is inherently a three-dimensional concept. So capturing the three-dimensional world as a two-dimensional image presents challenges when striving to preserve depth. These challenges are mostly related to the fact that, unlike the real world, two-dimensional images lack stereo cues, and stereo vision is a major component of the mechanics of depth perception. This is one limitation that 3D cinema tries to overcome. This article is about 2D images though, and the ways to exploit stereo unrelated (monocular) cues to suggest depth. Read More

With the advent of the digital SLR as a video capturing device in recent years there is a lot of raving on the internet about the “cinematic look” one can achieve with DSLRs. Cinematic look is often opposed to video look or TV look. On forums and blogs one can read both delusions and truth regarding this distinction. As is often the case with any hype – hype has the tendency to self-amplify – a lot of noise gets picked up and reiterated in such a discussion. This series of articles will attempt to examine in some detail the various characteristics of the cinematic look and then explore how they relate to the image of video capturing devices, including HDDSLRs. Hopefully, some myths will be cleared in the process. This first part in the series is focused on aspect ratios and sensor sizes and the closely related topic of depth of field.
