Finally, here is a video series that not only introduces Photoshop to beginners but also demonstrates powerful processing techniques used by experienced astrophotographers.
This video series begins with a tour of Photoshop that highlights the most common tools used to adjust and enhance images. Every relevant button, tab, and menu is described and subsequently used to process and improve pictures. Photoshop specific concepts of Layers, Masks, and Blending Modes are thoroughly explored and used. Each section shows concrete examples of significant “effects” you can start using immediately on your own images.
Several of Adam's signature techniques including Shadow/Highlights for LRGB, the Screen technique for blending H-alpha data, and the Multiply contrast enhancement all make an appearance. In addition topics such as alpha channels and batch processing make an appearance for the first time. This tutorial is rounded out with two example processing sections (Techniques, sections 10 & 11) which include the base data for you to follow along with. Visit the content pages for the major chapters below to see all of the material being covered.
By the end of this instructional experience, you will not only understand Photoshop more intuitively but also begin to synthesize the techniques shown and develop your own image processing solutions and enhancements.
