What type of background works best

Luna4 can automatically detect colors connected to edges or allow you to choose the background with one click. After processing you can erase or restore areas with the brush before downloading the transparent PNG.

How to improve the result

  • Use an image where the background clearly reaches the edges.
  • Start with medium sensitivity and gradually increase it.
  • If the automatic fails, select a representative area of the background.
  • Use Erase, Restore, and Undo to refine the edges before downloading.

Frequently Asked Questions

Does the output retain transparency?

Yes. The result is exported as PNG to preserve transparent areas.

Why are there sometimes remains of the bottom?

The tool attempts to separate the background by color similarity and connection to the edges. In complex scenes, background and subject may share colors and the result needs more precision.
