Technical effects like emboss and edge detection reveal structural details normally hidden in a photograph. Emboss simulates raised, 3D texture by highlighting edges with directional light — useful for creating textured backgrounds, product mockups, or artistic interpretations. Edge detection isolates the outlines of objects, producing line-art-style images useful for technical illustration, coloring page creation, or design reference.

Pre-processing tip: Both effects respond strongly to image contrast — increase contrast first for more defined results. Use the color tools to boost contrast and sharpness before applying for crisper edges and more pronounced textures.
