Please review your Photoshop papers and notes taken in class. If you have any questions, cannot find one of these definitions or don't understand something, do not hesitate to ask Mrs. Feld. Check the "Photoshop" section in this blog (October 21st's entry). There you can find a good definition, as well as descriptions of the tools used in the program.

ADD THE FOLLOWING TO YOUR NOTES:

Layers: Photoshop's layers can be thought of as separate films, much like transparency sheets. Each layer contains its own discrete contents. Individual layers contain objects which together create your composite image. Layers are "everything" in Photoshop! Each object in Photoshop exists on its own individual layer, making it easy to control the position and quality of each layer. Layers give you flexibility when you make changes. By placing images, effects, styles, and type on separate layers, you can modify them individually without affecting other layers. You can add, delete, and move layers in your document.

When you select a layer in the Layers palette, that layer is active (when you're working in Photoshop, make sure that the desired layer is selected). Review the following tips to learn about active layers:

• Only one layer can be active at a time.
• The name of the active layer appears in the title bar of the image window.
• Changes affect only the active layer even though you view the whole image in the image window.

The Layers palette is your essential tool for working with layers. It contains a list of all the layers, starting with the topmost layer. To the left of the name is a thumbnail of the contents of each layer. You can use the Layers palette to perform many tasks (e.g., create, delete, hide, merge, and flatten layers).

You may find it useful to hide layers while working in Photoshop. For example, when merging layers, you can hide some layers so that they will not be merged. Visible layers have a VISIBILITY icon (the "eye") next to them; hidden layers do not. Get used to working with layers - they're extremely important in Photoshop. Practice changing their order (like the exercises we did in class), hiding, copying and deleting layers.
