Line

the point on a path

Value

relative light and darkness

Color

reflected light

Form

three-dimension lines and shapes

Space

Height and width between two images

Shape

perceivable two-dimensional area

Texture

surface quality

Pattern

repetition of an image or shape. Can also be described as decorative surface design

Balance

Equalizing the visual weight of elements

Movement

what guides your eye through an image

Variety

concerned with contrast and difference

Harmony

Pop art are color and vibrant pieces of artwork based off of real-world objects. Andy Warhol.

Pixels

Picture elements arranged in columns and rows. They are the smallest unit of information in a computer display or image.

What 2 types of digital art did we look at and use in this class? What is the difference?

• Digital imaging: the combination of many different photos to form one photo (photoshop)

• Digital Drawing: Just like physical drawing, except with a tablet and a computer. (Corel Painter)

What is a Photomontage?

A multi-image picture created with a photographic film or digital process. Often done to convey a message. If done correctly, can have a dramatic impact.

PSD File

An image format that supports layers of graphics in a single file.

JPG File

A widely used compressed image format.

What is the difference between a PSD and a JPG file?

A PSD file retains layers while a JPG file does not.

Digital Imaging

The process of altering images with a computer, digital camera or scanner, and printer

Corel Painter

A raster-based digital art application. It is essentially paper and pencil but with a tablet and pen.

Adobe Photoshop

A raster graphics editor used to combine, retouch, and change images.

Adobe Illustrator

A vector graphics editor and design program

Resolution

• Typically described in PPI (pixels per inch)

• Higher resolutions mean that there are more PPI, resulting in more pixel information and creating a high-quality, crisp image

Photoshop Layers

Photoshop layers are used to add multiple images into a work. This way, users can edit each image without it affecting other images. Each image gets its own layer.

Photoshop Selections

An area in the photo that the user can define. In this selection, users can change the color, vibrance, and saturation. Use the select subject tools to select what you want to change and erase any part you don’t want.

Photoshop Layer Masking

A non-destructive way to hide parts of an image or layer without erasing them. Use the layer mask button to add a layer mask to the selected layer, then use black to take away and white to add back.

Photoshop Adjustment Layers

Adjustment layers are a special type of layer that manipulate the color and tone of the layers beneath them. Use the adjustment layer button to add an adjustment layer.

Symmetrical Balance

A 50/50 balance or a mirror image. The image would look the same on either side of the center.

Raster art/Bitmapped Images

• Composed of Pixels, similar to a real photograph

• Generated with a paint program or scanned-in from a print

• Resolution dependent

• Resolution determines the size of the file and the "sharpness" of the image 

• Cannot be enlarged "resampled" without some loss in quality of the image. The image loses some detail and sharpness

Vector Art

• Created with mathematical formulas

• Made up of paths, with a start and end point, and contain straight lines, curves and angles.

• A path can be a line, a square, or freeform shape.

• Do NOT contain Pixels

• CAN be enlarged or reduced without any loss in quality

Cross-Hatching

• Use intersecting lines to create value

• The closer the lines are, the darker the value becomes

Scribbling
