Cheat Sheet

  1. DPI vs PPI & Image Resolution -

    Understanding DPI (dots per inch) and PPI (pixels per inch) is crucial for accurate print and screen output. Use the formula PPI = pixel width ÷ physical width in inches and aim for 300 PPI for print versus 72 PPI for web (Adobe Photoshop Docs). Remember "High PPI = High Clarity" to lock in this essential concept.

  2. Raster vs Vector Graphics -

    Raster graphics comprise a fixed pixel grid while vector graphics use scalable paths defined by math equations, meaning vectors stay sharp at any size (W3C). A handy mnemonic is "R is for Raster, Rigid Pixels; V is for Vector, Versatile Paths." Logos and icons often leverage SVG vectors for crisp resizing across devices.

  3. Lossy vs Lossless Compression & File Formats -

    JPEG uses lossy compression to reduce photo file size by discarding data, whereas PNG and TIFF are lossless, preserving every pixel (ISO 12234-2). Think "Junk in JPEG, Perfect Pixels in PNG" to choose wisely: photos go JPEG; graphics with transparency go PNG. This distinction is tested often on the graphics types quiz.

  4. Seven Elements of Art -

    The foundational elements - line, shape, form, value, space, texture, and color - guide strong design and frequently appear on the elements of art quiz (Khan Academy). Use the acronym LSFVSTC to recall them quickly or chant "Lines Shape Forms, Value, Space, Textures, Color." Mastering these principles boosts every edit and composition.

  5. Rotation & Non-destructive Transformations -

    Convert layers to Smart Objects before rotating or scaling to avoid pixel degradation in Photoshop (Adobe Help Center). Rotate in exact increments - hold Shift for 15° steps or snap to 90° - to keep edges crisp and aligned. Practice non-destructive workflows in GIMP or Photoshop to ace the image editing quiz and work like a pro.
