There are a few things you need to know if you want to trace in Photoshop. First, the tracing tool is located in the Tools palette, and it is the top left tool in that palette. Second, you will need to select a layer or object to trace. Finally, you will need to set up your tracing parameters. Here are some of those: -The tracing width (in pixels) is the size of the area you want traced. -The tracing height (in pixels) is how high up or down the layer or object you want traced. -The number of lines per inch (LPI) is how many lines per inch your traced area will have. -The line width (in pixels) is how wide each line in your traced area will be. -The line height (in pixels) is how high up or down each line in your traced area will be.
