Flash applets on some technical aspects of photography (original) (raw)

These applets are designed to supplement the course lecture material in CS 178. They will typically be demonstrated live in class, then added to this web page. At that time they will also be linked into thecourse scheduleand the course home page. The applets were designed by Marc Levoy and built by CURIS students Nora Willett and Katie Dektar, and PhD student Andrew Adams in the spring and summer of 2009.

Exposure

Lens Applets

Thin Lens

Uses Gauss's ray tracing construction to show how thin lenses perform a 3D perspective transformation of object space into image space.

Depth of Field

How do focal length, subject distance, F-number, and size of the circle of confusion affect depth of field?

Telephoto Zoom Lens

The operation of zoom lenses, telephoto zoom lenses, and optically-compensated telephoto zoom lens.

Convolution

Spatial convolution

Interactively demonstrates 1D continuous convolution and 2D discrete convolution. Don't miss the "custom" buttons!

Autofocus

Color

Introduction to Color Theory

Explores the trichromatic theory of color vision and considers its implications for human perception, color photography, and computer display of color images.

Color Matching

Reenact Maxwell's color matching experiment to see how closely you can match the trichromatic matching functions for the given primaries.

Chromaticity Diagrams

Explores chromaticity diagrams and the meaning of the 2D gamut of perceivable colors.

Gamut Mapping

Interactively shows the results of gamut mapping (both the primaries and the rendering intents) on the colors displayed in an image.

Color Mixing

Explores additive and subtractive color mixing.

Gamma

Panoramas

Cylindrical Panoramas

Demonstrates how images are projected from a plane to a cylinder to form a panorama.
