In Aperture 3 Essential Training, author Derrick Story covers the entire photographic workflow in Aperture, from import to enhancement to output. The course covers organizing image collections using star ratings, labels, and Smart Albums, and using the image editing tools to correct exposure, retouch flaws, and correct color balance issues. One of the most noteworthy enhancements in Aperture 3 is explored in detail: its ability to store video clips alongside the stills from digital cameras, then combine them to create stunning multimedia slideshows. Exercise files are included with the course.
