Study Notes
Color Models
- The RGB (Red, Green, Blue) model is used by computer monitors.
- CMYK (Cyan, Magenta, Yellow, Key/Black) model is for commercial printing, such as magazines.
Gamut and Color
- Gamut refers to the range of colors a color model can produce.
- The total spectrum varies based on the color model used.
RGB and Image Depth
- An 8-bit RGB color depth can create 256 colors.
Image Transparency
- An alpha channel controls color image transparency, varying opacity.
Image Types
- Vector images consist of lines, curves, and fills, unlike raster images.
- Raster images become pixelated when zoomed in and have larger file sizes.
Bitmap Tracing
- Bitmap tracing converts a vector image into a raster image.
Image Optimization
- Key aspects of optimizing a raster image include resolution and file compression.
RAW Image Files
- Uncompressed RAW file types can be obtained by downloading from digital SLR cameras.
Undefined Colors
- Undefined colors in a web browser result in dithering, creating new colors through interpolation.
Pixel Dimensions
- An image measuring 72 dpi at 8 inches wide is 576 pixels wide.
Bicubic Resampling
- Bicubic resampling is ideal for enlarging images, enhancing quality.
Fonts
- Serif fonts are traditionally used in print for readability, while sans-serif fonts are cleaner and instill trust.
- Serif fonts have decorative end points, while sans-serif fonts lack these features.
Elements of Design
- The seven design elements are Line, Shape, Form, Space, Value, Texture, and Color.
Lines in Design
- Lines are basic components of shapes, influencing length, thickness, and direction, and creating movement and focus.
Shapes in Design
- Shapes define boundaries and can be geometric, creating form and stories in images.
Texture in Design
- Texture implies how an object might feel and evokes sensory experiences like touch and taste.
Color and Emotion
- Color influences human emotions and moods, being visually pleasing and creating comfort.
Form and Space
- Form represents three-dimensional structures through two-dimensional shapes.
- Space defines the area or volume within a scene, with positive space occupied by primary objects and negative space surrounding them.
Value in Design
- Value is achieved through the use of light and dark to create highlights and shadows.
