Opacity

Opacity measures the degree to which a surface blocks light, ranging from 0% (fully transparent) to 100% (fully opaque). It is fundamental in digital design for layering, transparency effects, and blending.

Key Applications

• Adobe Photoshop:
  • Brush opacity controls stroke transparency (adjustable via brush settings panel; e.g., 5 for 50% opacity).
  • For brush tool usage (size/hardness adjustments), see Julianne Kost using brush tool in photoshop.
• CSS: opacity property sets element transparency (e.g., opacity: 0.7).
• SVG: opacity attribute defines shape transparency.
