Overview
Analyze the composition of any image and video
Compo Grid overlays master composition grids directly on the images and videos of the pages you browse, on any website. No screenshots to take, no separate software to open: the grid is overlaid directly on the artwork you are viewing. For painters, illustrators, photographers, and art students who want to understand how an image is constructed from the inside out. NEW: • Drawing mode: annotate artwork with a pencil, freehand strokes, lines, rectangles, ellipses, or arrows, using six colors and a highlighter. Annotations stay attached to the image and are included in PNG exports. COMPOSITION GRIDS • Rule of thirds, golden ratio, and diagonals • Armature, rabatment, and reciprocal diagonals • Dynamic symmetry and golden spiral • Mechanical grid with free divisions Note: grids that require a specific format, such as the golden spiral, are only displayed when their construction is correct. Otherwise, Compo Grid explains why. VALUE ANALYSIS • Black and white, soft notan, two-value notan, and blur • Mirror: fold the image onto itself to assess its balance • φ (phi) compass: measure golden sections on any subject, including portraits VIDEO AND EXPORT • Display grids over videos • Automatically detect film letterboxing to adjust the grid • Easily save an image or video frame with its grid as a PNG PRACTICAL FEATURES • A keyboard shortcut for every available grid and tool • Adjustable line color, thickness, style, and opacity • Choose which websites the extension runs on • Right-click an image to display its grid or save it PRIVACY No account, no data collection, no advertising.
