Computational Photography CS 498 Ben Bower Computational Photography

What is computational photography? What is it used for? Computational imaging techniques High Dynamic Range Imaging Light fields Light Field Rendering Synthetic Aperture Photography Relighting Through Computation

High Dynamic Range (HDR) Imaging Increasing the color contrast and range HDR imaging for static scenes non-static scenes

Light Fields A function of the amount of light traveling in every direction through every point in space. Light Field Rendering Synthetic Aperture Photography

Light Fields Light Field Rendering

Light Fields Synthetic Aperture Photography First observed by Leonardo da Vinci This idea can be used in photography with an array of cameras

Relighting Through Computation Changing the lighting of an image Intensity Color Origin of light

Relighting Through Computation Light is additive This concept is used to change the intensity and origin of the light Color Scaling the color channels of an image

Light Stage

Summing it up... Computational photography is still new It has many applications and will continue to grow as technology increases
