§ 12.11.23 - Darken

Scripting command: darken [Amount=0...200] [Limit=0...255]

Note: All available scripting operations are listed on the Script operator page.

Darken lets you set a maximum threshold with Limit , and an Amount to darken all pixels under that limit. It is useful for dropping a constant noise level such as that found in many astrophotos without a very significant impact on bright objects.
