Graphics Knowledge Exam

Today was the day we wrote our test on "Adobe Photoshop Elements". The test itself was pretty straight forward and I believe if you paid attention in class and did all the work you probably did fine. Even saying that, I'm still nervous about my own mark but that is inevitable. Below are a few things that were either on the test, mentioned in class, or are in some other way significant and related to our work on Photoshop Elements.

Aspects:
-Resolution: This is the pixel to inch ratio, or how many dots per inch are in your image. 300 for print images, 72 for internet purposes
-Canvas Size: This refers to the width and height of your canvas, the most common print size is 4 x 6 (inches).
-Hexadecimal Codes: The values used to represent all of the 16.7 million hues available to work with.

Tools:
-Marquee Tool: Either retangular or elliptical, used for selection.
-Paintbrush: Used to paint directly on to the canvas with varying brush sizes.
-Lasso: Freeform selection tool.
-Dodge/Burn: Used to darken or lighten an image, name comes from actual chemical processes that were used in the past.
-Sharpen/Blur: Used to blur or sharpen an image.
-Crop: Cut or clip your image to the desired part and discard the rest of the image.
-Gradient: Used to spread from the background colour to the foreground colour. (Acheives a faded effect with one colour blending into the next.)
-Smudge: Does exactly what it's called, smudges.
-Eraser: Again, no brainer, erases.
-Clone Stamp: Clones from a source. Takes one part of an image and duplicates to another part of the image.
-Horizontal/Vertical Type Tool: Adds text either flowing horizontally or vertically to the image.
-Eyedropper: Selects a colour in the image and sets it to the foreground colour. Handy when identifying or narrowing down colours in an image.
-Magic Wand: Used to select parts of a picture, determined by the hexadecimal code fo a colour and controlled by the tolerance setting.

Palettes:
-Layers: Displays all your layers, their visibility and all the effects that have been applied to them.
-Navigator: Shows you an overview of your picture, the percentage your viewing it at and allows you to move around the image.
-History: Records and shows you previous actions that have been taken.
-Layer Styles: Lists and allows you to apply the different layer styles available.
-Swatches: Shows you different basic colours you can use.
-File Browser: Allows you to navigate through your files and open them.
