Photoshop: Getting to Know Layers Computer Information Technology Section 7-5

Objectives The student will:  Understand and use layers  Use Layer masks  Understand clipping masks  Use Marquee tools to create shapes

Layers Layers are like clear pieces of film each containing it’s own image  Layers can be stacked on top of each other  Each layer is independent and can have it’s contents and opacity changed  Layers can be reordered  Blending modes can be changed to create interesting overlays

Creating a New Blank File So far we have edited existing images, but sometimes you want to build a file from scratch Choose File>New

New Layer Dialog Box Size in either inches or pixels Resolution (72 is good for viewing on PC) Color Mode – RGB is best Background – White, a color or transparent

Adding Shapes Use the Shape Marquee tool to add a shape to the image

Naming a Layer Sometimes it’s easier if layers are given names  Double click on a layer name to edit the name

Using Masks in Layers Using a layer mask allows for better blending and more realistic compositions Mask allow special effects to be added  Gradients, etc

Adding a Shadow Holding the ALT key when moving a layer will make a copy of the layer Change Color Add a Gaussian Blur to make the shadow more realistic (Filter>Blur>Gaussian Blur)

Rest of Today Read and do the Exit Pass in today’s opener. 1. Once you have colored the silverware… 1. Add a layer on top of the placemat and use the Marquee Tool to create a plate. Color and texture it as you wish. 2. Add another layer on top of the plate and use the Marquee Tool to create a piece of food on the plate. Color and texture it as you wish. 3. Finally, add yet another layer on top of the food. Use the Marquee Tool to create an abstract, geometric bug sitting on the food. Color and texture it as you wish.
