    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.
