Study Notes
Digital Media 4e - Chapter 2: Image Files
-
This chapter focuses on image files, specifically raster files
-
Paint programs use pixels
-
Pixel—a specific color at a specific location in a grid
-
Drawing programs utilize vectors or lines
-
Examples of programs are provided for both raster and vector (e.g., Adobe Photoshop, Microsoft Paint, Corel Paint Shop Pro, GIMP)
-
Raster-based paint programs assign each pixel with x and y coordinates, creating a raster/bitmap image
-
Enlarging raster images causes pixilation, while reducing them results in loss of sharpness
-
Common non-native raster file types:
- BMP: Used in word processing; large file sizes; usually 256 colors
- JPG: High quality; 16 million colors; commonly used, compressed format
- GIF: Small file sizes; mainly for line art, transparency, or animated graphics
- TIFF: Works well in various environments; large file size; 16 million colors; used for print documents
-
Non-native vector file types:
- EPS: General-purpose vector file; data and preview in one file; commonly used for print
- SVG: Web-based vector; use HTML code; small file sizes; popular on mobile devices
-
Licensing fees related to GIF compression. Specifics on CompuServe decisions are also noted
-
Format conversion to different formats
-
Understanding of compression (lossless and lossy)
-
Lossy compression reduces file size by discarding less essential information
-
Lossless compression preserves all pixel data.
-
Image quality of JPGs depends on compression levels (1-12)
-
Understanding resolution, resizing and resampling:
- Pixel density (ppi) defines image resolution
- Resampling influences image quality during resizing
- Maintaining aspect ratio during resizing
- Formulas calculate colors for new pixels in resized images
Digital Media 4e - Chapter 4: Digital Photography
-
Two basic camera categories: DSLR (digital single lens reflex) and point-and-shoot
-
DSLR cameras: high image quality, adaptability, faster performance, more manual control, "what you see is what you get" (WYSIWYG)
-
Point-and-shoot cameras: less expensive, more portable, easier to use
-
Camera features including shooting modes, megapixels, optical and digital zoom, file types (JPEG, RAW)
-
Camera care and safety
-
Taking photographs: candid shots (unplanned), photographic composition (selection and arrangement)
-
Compositional elements (line, shape, color, lighting)
-
Compositional principles (unity, balance, perspective, emphasis)
-
Focal point, rule of thirds, framing, leading lines, depth
-
Directional lighting: front, side, back lighting
-
Depth in photography, including terms like foreground, middle ground, and background; perspective and angles
Digital Media 4e - Chapter 5: Color in Digital Media
- Different color models (RGB, CMYK, HSB) explained
- RGB—additive color model using red, green, blue light to create colors on computer screens
- CMYK—subtractive color model using cyan, magenta, yellow, and black pigments, useful for printing
- HSB—based on human color perception, using hue, saturation, and brightness
- Importance of color mode selection based on output device (screen vs. print)
- Color theory concepts including: hues, neutrals, shades, tints, tones, grayscale, complementary, and analogous colors
- Color psychology and its effect on design
- Application of color palettes to branding strategies using specific color themes, including monochromatic, complementary, analogous, and triadic concepts
- Web-safe colors and the Pantone matching system (PMS)
Digital Media 4e - Chapter 6: Raster Editing
- Raster editing software tools such as Photoshop and other applications
- Tools and techniques for image selection (marquee, lasso, magic wand tools)
- Working with selection settings like anti-aliasing, feathering, tolerance, and contiguous
- Using Quick Mask mode for selections
- Adjusting image brightness and contrast using tools like the Curves panel
- Importance of cropping, and retouching tools for content alteration
- Ethical considerations with retouching
- Understanding the concept and usage of layers and layer masks in editing which includes nondestructive editing
