This document summarizes the key technologies and techniques learned from creating a product in Photoshop, including: 1) Using the marquee tool to outline an image and then transforming it to make it smaller or larger and rotate it. 2) Applying transformations to images to reshape, rotate, move, and place them in the desired location over other elements. 3) Using the magic wand tool to select and highlight backgrounds, then deleting to make the background transparent. 4) Employing the paint bucket tool to change the color of backgrounds, such as making a background dark grey.
