2.01 Understand Digital Raster Graphics

Image Editing1Aspect RatioAspect Ratio is the relationship of an objects 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.

CroppingCutting out part of an imageOriginal image retains same file sizeCut image can be saved as new object

3LayersCompiling multiple pictures or objects together into one imageLayers can be turned on or offElements can be colored, layered, and resized individually

4SelectionsSelections 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.

TransformingTransforming 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.

6Layer StylesLayer Styles One or more effects applied to a layer or layer group. Effects include shadows, stroke, glows, bevels, and overlays.

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

Fills and GradientsFill - 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. ExamplesDark blue, gradually becoming white Red fading to orange.

9Adjustment LayersAdjustment Layers Non-destructive layers that can be added to allow you to apply image tonal and color adjustments.

FiltersUsed to apply special effects to an image that would be too difficult to create manually.Examples of use:A weaving patternLiquefying

11CloningCloning - 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 models skinBrush up text on a scanned image

12Blend ModesBlend Modes change the way layers interact by determining how a layer will blend with the layers below it.
