A FEW NOTES….
The name of the game in PhotoShop is layers. You must have a good understanding of how layers work (think of paper dolls!) in order to make really nice digital artwork.
Layers have an opacity level. Opacity refers to the transparency of the layer, how much you can see through it. If a layer has 100% opacity, you cannot see through it. Opacity is the measure of how opaque or see-through a graphic or a piece of paper is.
SOME VOCABS…


Adjustment Layer

A special type of layer that lets you experiment with color and tonal adjustments to an image without permanently modifying the pixels in the image

Aliasing

The jagged edges on curves and diagonal lines in a bitmap image. These jagged edges are commonly called jaggies. Enlarging a bitmap image accentuates the effect of aliasing or jaggies

Anti-aliasing

The process of smoothing out jaggies on a graphic

Brightness

The intensity of light illuminating the graphic

Byline

Short phrase or paragraph that indicates the name of the author

Crop

To cut out or trim unneeded portions of an image or a page

Duotone

When a photograph is printed using two ink colors

Embossing

The creation of a three-dimensional design or image on paper

Feathering

The process of softening the edges of an image in the foreground so that it blends into the background image with less contrast

GIF (Graphics Interchange Format)

.


A graphics file format developed by CompuServe to allow exchange of image files across multiple platforms and it a standard graphics format on the Internet. Uses only 256 colors.

Gradient

When elements within a specified area are filled with a smooth transition between two or more colors

Hue

Color (as in the color wheel.)

JPEG (Joint Photographic Experts Group)

A file compression standard that is best used for photographs. JPEG is a lossy compression algorithm, meaning that is slightly degrades image quality. Uses 16 million colors.

Masks


Way of protecting specific areas of your image, just as you would use masking tape when painting your house. A mask consists of a grayscale channel, called an alpha channel and is often displayed as a ruby overlay so the underlying image can be seen through the mask. The darkest areas of a mask are the areas most protected and the white areas are unprotected. Shades of gray represent areas of partial protection that corresponds with the level of gray.

Monochrome

A black-and-white photograph or slide; painting done in a range of tones of a single color; having or appearing to have only one color

Opacity

Measure of how opaque or see-through a graphic is

Opaque

Not see-through, non-transparent

Saturation

An indication relating to the richness or vibrancy of the color

Scale

To change the size of an object while maintaining its shape

Sepia tone

A reddish brown monochrome tint. When applied to a photo, it gives the picture a warm, antique feeling

Transparency

A measure of how see-through something is or how much light can pass through

Watermark

An image or text that appears on the background of a graphic to decorate or prevent illegal copying of the graphic

Complete the tutorials listed below for completion points. Upon completion of these tutorials, you will complete several projects. Be sure to keep all of your work and to clearly name each item so you can locate it for printing. Completing tutorials should help you to better learn PhotoShop so that you can complete the more complicated assignments later. Be sure to save frequently!! You receive 20 points for completing each tutorial correctly.

  • Tutorials #1 and #5 are from
    http://homepage.cs.uri.edu/tutorials/PhotoshopEl/Help/help.html

  • Tutorial #3 is from http://www.pacific.adobe.com/products/tips/photoshopel.html

  • Tutorials #2 and #4 are from http://www.adobe.com/education/curriculum/ps_elements_tutorials.html

Your project does not have to use the same colors or shapes, but do use the same ideas (gradients, layers, etc.).


TUTORIAL #5

SUPPLEMENTAL PROJECTS

If you finish early, try some of these


Obtain a photograph that has “redeye” in it. Then, use this tutorial to remove the redeye. Be sure to print your before and after photograph. This must be an original photograph (so ask to borrow one from someone or take one… seems it happens more than we want it to anyway) and not one from the internet someplace.
