Compositing is the combining of visual elements from separate sources into single images, often to create the illusion that all those elements are parts of the same scene.See the Files for Students for example files.Demo 1: Double Processing a Single RAW File for Color Temperature
In the first exercise, we will process a single RAW file twice to create a new image that has correct color temperature overall. (Use move tool to drag one image on top of the other. Hold SHIFT when dragging and images will align perfectly)
Demo 2: Double Processing a Single RAW File for Exposure/ Smart Objects
In this exercise we will process the same file twice to create a new file that has correct exposure overall. Each time you open the image from Camera Raw, hold down shift and open as a “Object”. Once you have processed the image twice, hold SHIFT when dragging and images will align perfectly. Use gradient tool and brush tool to paint in certain areas. You may need to decrease the opacity of your brush tool. Double click the smart object layer to refer back to the original raw information.
Demo 3: Layering Several Images to get correct exposure
By bracketing, shoot the same scene with multiple different exposure settings so you can increase the dynamic range of the image. Shoot Several Images of the same scene on a tripod, then layer them on top of each other and create masks to achieve an overall correct exposure. Mask the images together to get information in all areas of the image. (This is an alternative to HDR)
Demo 4: Layering Images of the Same Scene
Using several images of the same scene shot on a tripod, one can create a new composite image of this scene that never actually existed. Capture several different frames of the same scene and then layer them to embellish or eliminate certain information. For example, you could shoot several frames of a busy street corner and mask them together to either make all of the people crowded together, or eliminate the people all together.
