Raster Image

A type of file format that stores images as a set of pixels. Each pixel represents a specific color. When you enlarge a raster image, the pixels become visible, making it appear pixelated.

Vector Image

A type of file format that uses mathematical formulas to define shapes and lines. Vector images can be resized without losing quality, making them ideal for logos and illustrations.

PSD (Photoshop Document)

A native Photoshop file format commonly used as a work file for editing and creating images. It supports layers, Photoshop properties and effects, and is a lossless format, preserving original image quality.

JPEG (Joint Photographic Experts Group)

A widely used image format for web use, known for its compression capabilities that reduce file size. It comes with a trade-off: the compression process often results in some loss of image quality.

Study Notes

File Formats

  • Raster vs. Vector files: Raster files are made up of pixels, while vector files use formulas. Raster files lose quality when enlarged, while vector files remain sharp at any size.

Raster File Formats

  • Common formats include PSD, JPEG, PNG, GIF, TIFF, EPS, RAW, and PDF.
  • File size, quality, transparency, and compatibility are factors to consider when selecting a format.
  • PSD: Native Photoshop format, used for master files, lossless, supports layers, large filesize.
  • JPEG (Joint Photographic Expert Group): Commonly used for viewing and sharing, lossy, lower quality but smaller filesize.
  • PNG (Portable Network Graphics): Better replacement for JPEG/GIF, more colours than JPEG, lossless, relatively small size, not supported by older browsers/printers.
  • GIF (Graphics Interchange Format): Commonly used for web graphics, animations, stickers, lossy, limited colour pallet.
  • TIFF (Tagged Image File Format): Similar to PSD, lossless, layered, high quality, large filesize.
  • EPS (Encapsulated Postscript): Universal standard for commercial printing, print industry standard, requires a preview image.
  • PDF (Portable Document Format): Ideal for viewing, sharing, and printing, supports all Al properties, lossless or lossy.
  • RAW : Used in photography, contains all raw image data from a camera.

Vector File Formats

  • Common formats include AI, EPS, PDF, and SVG.
  • AI: Adobe Illustrator format, used as master file, works in other Adobe programs, legacy versions work with other programs.
  • EPS (Encapsulated Postscript): Older format, doesn't have all AI properties, encapsulates vector as image.
  • PDF (Portable Document Format): Ideal for exchange, supports AI properties.
  • SVG (Scalable Vector Graphics): XML-based format, readable by computer and humans, ideal for web (supported by most modern browsers), scalable, no special layer properties or effects.

Export Options in Photoshop

  • Save As: Saves the image to various formats, preserves layers/editing capabilities, but the file size can be large with many layers.
  • Export As: Ideal for web use, optimized for web use, smaller file sizes.
  • Quick Export (PNG/JPEG): Fast way to save image with default settings.
  • Export for Web (Legacy): Optimizes images for web use, various quality and file size settings.
  • Export Layers: Exports each layer in the PSD as separate image files.
  • Artboards: Exports individual artboards.
  • Generator: Layer names, Photoshop automatically exports layers (in a separate folder) when changes are made. Useful for assets that require constant updates.

Font Formats

  • TTF (TrueType): Developed by Apple, vector outline fonts, compatible on Mac and Windows, used for print and screens.
  • OTF (OpenType): Newer version of TTF, developed by Microsoft and Adobe, supports more glyphs (characters), includes stylistic alternates, fractions, numerous other features, supported on Mac.
  • WOFF (Web Open Font Format): Suitable for websites, quickly compresses the font, allows faster load times and better compatibility with modern browsers.
