This document provides instructions for manipulating a portrait image in Photoshop using techniques like resizing, layering, posterization, and adjusting colors and contrasts. The objectives are to learn basic Photoshop techniques, understand resizing and layers, apply the posterization effect, and relate the techniques to Andy Warhol's pop art style. The steps demonstrate how to open an image, convert it to grayscale, adjust brightness/contrast and posterize the image. It describes using the magic wand tool to select tones, copy them to new layers, and fill layers with different colors. Students are asked to repeat the process six times at smaller sizes to create color variations inspired by Warhol's work.
