Current research exists that is aimed at determining whether images have been subjected to methods of manipulation. While this research is thorough in its approaches to detection, it lacks methods that would facilitate the measurement of those manipulations. This study uses Photoshop to measure the qualitative changes in images. The aesthetic dimensions set forth by Gillian Rose (2007) such as content, color, spatial organization, and light can be isolated, manipulated, and ultimately measured. This research is aimed at facilitating additional questions regarding what constitutes image manipulation, the extent of image manipulation using the methods described herein, and how image manipulation may affect the viewer. It also hopes to show that widely accepted practices of image modification need to be revisited as technologies continue to update at an unprecedented rate.
