generating HDR images Dynamic Range is the ratio between the lighest and
darkest parts of a scene Ratio of two luminance values which are measured in

Mimic a greater dynamic range;
Improve image contrast;
Improve image detail. •Technical Overview of how HDR Images work;
•Create Images using built in MATLAB functions
•Discussion of Advantages and Disadvantages concerning HDR vs. Conventional Imaging Techniques Project Objectives •Select neighborhoods to be photographed; West Philly
Old City •Create and apply Matlab HDR Script •Apply Adobe Photo Shop Photomatix HDR Suite Histogram Conventional HDR Two Types

Local - applies a different effect to each pixel according to the local features of the image.
produces better visual effects than global tone mapping, e.g. halos, ringing, and fantasy like images. Blurry Ghosting Disadvantages Results Yippee Skippy ZOOM This is a very long hallway and it scares me... welcome to my presentation
