Lesson Description
Here you work with the black buttons, designed for more subtle reduction in wide field or deep sky.
The key difference is that these do fit in very well when you have a layer of stars on Screen.
That's why you don't use NewIf you create a new layer, you break the flow of separate stars.
You will learn how to apply direct or duplicate, and how to evaluate the change by hiding/removing the original layer.
What you will learn
- Understand the purpose: subtle, DS/wide-field, separate stars.
- Apply layered reduction in Screen without using New.
- Compare correctly by hiding/removing the original layer.
- Complement with a dedicated curve fitting for stars.
Advice
When you are in Screen with separate stars, work in “summative layers”: duplicates, The integration is then adjusted by looking at what each layer brings to the table.
Practical Checklist
- Apply a black level on a layer of stars in Screen (no New).
- Duplicate, apply another layer and hide the original layer for comparison.
- Add a curve just for stars if you need fine tuning.
Technical Glossary
Deep Sky (DS): image of nebulae/galaxies where the manipulation of stars is usually more delicate.
Screen: fusion mode that adds luminosity (ideal for recombining stars).
