Re: [APML] Eta Carinae - Try This
This filter is also sometimes called an Erosion filter. It is useful on nebulas that
are buried in star fields. The limit of use is when the nebula becomes pitted. One
other thing to try is "hard light" instead of "normal" when doing the Edit/Fade
step. You can also protect sensitive areas of the nebula with masking.
