The document describes how the author used Photoshop to make mugs appear to float in a corridor. They took two photos - one with mugs on a chair, and one without - using a tripod for consistency. In Photoshop, they cut out the mugs using selection tools, repositioned and resized the mugs, added a floor reflection by flipping and adjusting a mug layer, and distorted the reflection for depth. The skills learned included basic Photoshop tools, selections, layers, opacity, and distortion.
