Close-up and macro photography
- [Narrator] The key to convincing emulation of close-up photography is depth of field. Artistic application of distance-based blur or bokeh gives the rendering plausibility. In addition to its traditional application of directing the attention of the audience. Many renderers model bokeh directly based on the size of a virtual lens iris or aperture. For 3D renderers that don't offer a physical aperture size, you can usually get satisfactory results once you understand these principles. The amount of blur is determined by aperture size. A larger aperture gives more blur. The maximum aperture radius for a real-world camera lens is in the range of a few centimeters. Apertures size also controls the range of distances that will be in focus. This is the apodemus depth of field. A larger aperture has a shallower field, a more restricted range of distances are in focus. In the real-world camera aperture affects both exposure and bokeh but usually in 3D programs these affects are controlled…
