In projection mapping, which challenge is commonly addressed by edge blending and keystone correction?

• A. Achieving a seamless image across multiple projectors.
• B. Matching audio levels.
• C. Organizing prop placement.
• D. Reducing script complexity.

Answer: (A)

Edge blending and keystone correction are used to create a single, seamless image when projecting with multiple projectors onto a surface that isn’t a perfect, flat plane. Edge blending smooths the boundaries where projector images meet, so the overlap region looks uniform in brightness and color rather than showing visible seams. Keystone correction adjusts the geometry of each projector’s image to compensate for angles and distortions, so everything aligns correctly on the target surface and with the other projectors. In practice, when you’re mapping visuals across a stage or a curved surface with several projectors, these tools prevent gaps, overlaps, and warped shapes. The other options relate to audio, prop arrangement, or the script itself, which aren’t addressed by edge blending or keystone correction.
