  2. Common Uses of Photoshop • Creating graphics for the web. • Modifying photos. • Creating textures and other 2-D backgrounds for games. • Note: No 3-D modeling features supported.

  3. Resizing/Formats/Cropping • Resize Images • Reduce or expand size of picture. • Resolution can not be added to an image. • File Formats Allowed • PSD, GIF, JPG • Cropping • Removing parts of an image off of the canvas.

  4. Gradients/Patterns • Useful for textures or backgrounds.

  5. Filters • About Filters • Filters are plug-ins in Photoshop. This means that you can download new plug-ins online for specific filtering effects. • Artistic Filters (Examples: Colored Pencil, Plastic Wrap, Watercolor) • Blur Filters (Examples: Gaussian Blur, Radial Blur)

  6. Filters (Continued)

  7. Filters (Continued) • Brush Strokes (Examples: Angled Strokes, Ink Outlines) • Distort (Examples: Glass, Ripple, Wave)

  8. Filters (Continued) • Noise • Pixelate • Render (Examples: Lens Flare, Lighting Effects) • Sharpen Image

  9. Filters (Continued) • Sketch (Examples: Chalk, Chrome, Plaster) • Stylize (Examples: Glowing Edges, Tiles) • And much more…

  10. Type Tool • Placing text in images. • Anti-aliasing makes the edges of your type look nice and smooth instead of all jagged. • Font size and type can be changed. • Crisp/Strong/Smooth Types

  11. Layers • All images in Photoshop are produced in layers. • Starting with the background layer, you can add or delete as many layers as you need to. • Layers can be combined.

  12. Layers (Continued) • All layers contain: • Opacity (Transparency) Value • Layer Mode (Examples: Normal, Overlay, Color Burn, Color Dodge)

  13. Selection Tools • Used to select certain parts of a layer (Example: Someone’s head or a particular building in a photo) and modify it. • Marquee Tool • Rectangle • Oval • Row of Pixels • Column of Pixels

  14. Selection Tools (Continued) • You usually want to select a more complicated shape than that, so… • You can add or subtract from certain areas of the selection. • For example, to add, simply hold down shift and make another selection. • To subtract, simply hold down ALT and make another selection.

  15. Selection Tools (Continued) • Lasso • Allows you to make the selection by manually drawing it out with a pencil tool.

  16. Selection Tools (Continued) • Magic Wand • Select all of the same-color or similarly-colored adjacent pixels. • Tolerance Level
