  1. Image Editing 2.01 Understand Digital Raster Graphics

  2. Aspect Ratio • Aspect Ratio is the relationship of an object’s width to its height. • Knowledge of required aspect ratios can assure proper proportions when creating new files, cropping, or making selections. • Maintaining aspect ratio while modifying an objects size ensures the object is not distorted. • Use shift when resizing with a corner handle. • Check constrain proportions when changing the image size.

  3. Cropping • Cutting out part of an image • Original image retains same file size • Cut image can be saved as new object Student Created

  4. Layers • Compiling multiple pictures or objects together into one image • Layers can be turned on or off • Elements can be colored, layered, and resized individually

  5. Selections • Selections – identifying a specific area of a layer or image that allows you to move or apply techniques to only that specific area on that specific layer. • Transparency - removing the background color of a raster image making it “see-through” in order to allow the image to blend in with its background.

  6. Transforming • Transforming – changing a graphics size or dimensions through commands such as scaling and rotating. • Scaling – enlarging or shrinking a graphic. • Rotating – pivoting an object around its center point.

  7. Layer Styles • Layer Styles – One or more effects applied to a layer or layer group. Effects include shadows, stroke, glows, bevels, and overlays.

  8. Layer Masks • Layer Masks – A non-destructive method which allows you to apply transparency to a specific portion of a layer with precise control.

  9. Fills and Gradients • Fill - putting a color, gradient, pattern, or texture into an object or area. • Gradient – filling an object with a smooth transition from one color to another. • Examples • Dark blue, gradually becoming white • Red fading to orange.

  10. Adjustment Layers • Adjustment Layers – Non-destructive layers that can be added to allow you to apply image tonal and color adjustments.

  11. Filters • Used to apply special effects to an image that would be too difficult to create manually. • Examples of use: • A weaving pattern • Liquefying

  12. Cloning • Cloning - samples and area of an image and then allows you to paint over another area of the image with the sampled area. Examples of use: • Remove blemishes on a model’s skin • Brush up text on a scanned image

  13. Blend Modes • Blend Modes – change the way layers interact by determining how a layer will blend with the layers below it.
