Using Photos in PowerPoint: A Compression Experiment with Canon Elph SD450

This experiment, conducted by Elliott McCrory on March 24, 2006, explores the use of photos in a PowerPoint presentation. Utilizing a Canon Elph SD450 camera, the original images have a resolution of 5.0 megapixels, with each photo averaging around 2 MB. The presentation includes various photos, including Linac pictures and images of signs and fire hydrants. The study compares file sizes before and after compression, revealing a dramatic reduction from 21.9 MB to just 0.274 MB, highlighting the effectiveness of compression in digital presentations.
