Affinity photo was recently on sale for 50% off and it is a steal at that price… or maybe you have a copy…in anycase
James Ritson has a great series of macros for it related to astrophotography…
Just adding this in based on your interests that you shared and incase you have a copy of Affinity
I think he also has a great set of tone mapping macros…
Most of it is free or contribution only …
I don’t personally do any of this now but it looks vary interesting…
FYI anyways in case its of any use or interest to you…
JR Astrophotography Macros v13 (32-bit & 16-bit)
Workflow aids for astrophotography editing, including functions like star eating, motion deconvolution, nonlinear compositing and sharpening and adding star glow. These macros work equally well for both OSC (one shot colour) and monochrome data setups.
- Perform automated normalisation tone stretching, logarithmic tone stretching, or apply a colour preserving tone stretch (similar to Arcsinh).
- Multi-Bandpass Sharpening (an implementation of the popular Absolute Point of Focus sharpening method), which enhances perceptual detail and sharpness in a very pleasing way.
- A variety of composition setups for different data set combinations, e.g. RGB, LRGB, SHO, HOS, HOO, HaOIII, RGB-HSO, HORGB, HORGB-L… the list goes on!
- Monochrome colour mapping for single grayscale data layers.
- Add star glow and brilliance to highlight detail.
- Remove excessive star detail to promote focus on other deep sky objects.
- Colour range luminosity enhancement to bring out specific detail.
- Add live, non-destructive star and background masks. Easily reduce background luminosity and star luminosity with additional macros that utilise these live masks so you can easily adjust them non-destructively.
- Create thresholded star masks.
- Various sharpening methods: gaussian subtractive sharpening, gaussian kernel edge-mask sharpening, weighted intensity (‘background’) sharpening, non-linear sharpening to avoid ‘panda eyes’ around high contrast star detail.
- RGB luminosity layers: boost channel detail e.g. for red spectrum objects.
- Motion deconvolution: remove slight star trailing.
See the included PDF for installation instructions and a detailed explanation of how to use the macros.
