What is the best way to add back stars removed by StarXterminator?  Does it work for both linear and non-linear images?

Hi Donald,

I have two interviews with Russ Croman on the details of this that answer your question:

In addition, I demonstrate the answer in a number of videos.

The simple answer is that:

1. If the images are linear, you add the stars back using Pixel Math. This is simple addition.

2. If the images are non-linear you screen them back. There are several methods for doing this (ImageBlend or PixelMath expression). 

For #1 you can review this video:

However, #2 is the far more common method to work with the stars and incorporate them into the image. 

Just look at any of the workflow videos (such as the LDN 183 example https://www.adamblockstudios.com/articles/ldn-183-rgb-2024-final-adjustments-and-commentary)
