JR Astrophotography Macros v13 (32-bit & 16-bit)

View PDF Readme

View Video Tutorial

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.

JR Astrophotography Example Documents

View PDF Readme

This is a set of 18 example .afphoto documents to demonstrate various astrophotography editing workflows in Affinity Photo.

Please note that you will require Affinity Photo 1.10.0 or later (updates are free, so users do not need to be financially restricted to a previous version).

Each document will allow you to fully explore the non-destructive layer stack—you can hide, show and manipulate layers and see how they all contribute to the final result.

These documents illustrate the most ideal editing workflows, taking advantage of Affinity Photo’s expanded toolset that can be used for 32-bit linear colour spaces: there is no need to flatten and convert to 16-bit in order to use a further range of adjustments, tools and filters.

I hope they give you some practical ideas about how to approach your own astrophotography editing within Affinity Photo!

All documents have colour-coded layers to help visually identify the layer structure. The colour code key is provided in the readme PDF.

Current documents are: California Nebula HOS – Cone Nebula Ha – Heart Nebula Ha – Helix Nebula HORGB-L – Orion Nebula OSC – Rosette Nebula SHO – Sculptor Galaxy LRGB – Tarantula Nebula HaOIII – Tarantula Nebula LRGB – Crescent Nebula OHS – Pleiades RGB – Squid Nebula OSH – Thor's Helmet HSO – North America Nebula OSC – Witch Head Nebula LRGB – Rho Ophiuchi LRGB – Vela Supernova Remnant OSH – Gabriela Mistral OSH.

JR HDR Tone Mapping Macros v3 (32-bit only)

View PDF Readme

View Video Tutorial

Fast, non-destructive macros that apply natural logarithmic tone mapping to your HDR images using procedural functions. Version 3 includes two additional tone compression methods which apply one non-destructive layer with straightforward sliders, and revises the logarithmic tone mapping method to improve rendering speed.

  • Completely non-destructive, applied as a group that you can simply show or hide. Easily change the base exposure or add more adjustments to control the tone mapping effect.
  • Instant application: no delay required before the tone mapping can be applied. Run the macro and see your tone mapped result straight away.
  • Natural result: compared to Affinity Photo's Tone Mapping Persona, these macros will present a result that is more natural and closer to how the human eye would have perceived the scene.
  • Seamless 360 tone mapping: these macros are a great solution for 360 imagery! Tone mapping via the Tone Mapping Persona will leave you with a visible seam because the process is not seam-aware. These macros however will let you tone map 360 imagery with no seam when the image is projected.

See the included PDF for installation instructions and a detailed explanation of how to use the macros.

JR Blender Filmic Macros

View PDF Readme

See video tutorial (YouTube)

Instantly apply the Filmic view transform and looks to your 32-bit (EXR/HDR) renders in Affinity Photo non-destructively.

  • Emulates the Filmic view transform and looks (e.g. Very High Contrast, Low Contrast) that you can apply in Blender.
  • These macros are intended for HDR documents (OpenEXR, Radiance HDR). When saving to these formats, Blender writes out linear scene-referred values, so you do not get the Filmic view transform and looks applied.
  • Applying the Filmic view transform and looks in Affinity Photo is possible but complicated, and involves copying the Blender OpenColorIO configuration files and pointing Affinity Photo to them.
  • Instead, these macros can be added to a fresh install of Affinity Photo—no other dependencies like OpenColorIO—and you can apply the Filmic look you want non-destructively.
  • If you want, just apply the Filmic Log transform—no look—and shape the tones yourself using Affinity Photo's adjustment layers.
  • For convenience, move between different colour spaces non-destructively (Rec.709, Rec.2020, ROMM RGB, ACES CG, DCI-P3). Profiles are included in the macro file so are portable—no dependencies.

See the included PDF for installation instructions and a detailed explanation of how to apply the Filmic macros.

JR Sharpening Macros v2

View PDF Readme

Adds several non-destructive implementations of sharpening methods, including multi-bandpass sharpening, local contrast enhancement, gaussian mask sharpening, bilateral sharpening and more.

Provides much more flexibility compared to Affinity Photo's standard naive methods of sharpening (Unsharp Mask, Clarity, High Pass). Multi-bandpass sharpening, for example, provides smooth detail enhancement without over-sharpening noise and whilst minimising halo artefacts. The various kernel mask methods focus on enhancing edge detail and are very useful for soft imagery that may need more selective sharpening, such as wildlife photography.

Experimentation is encouraged with these sharpening macros: there is no one solution for sharpening that fits all imagery!

See the included PDF for installation instructions and a detailed explanation of how to use the Sharpening macros.

JR Matting & Keying Macros v2

View PDF Readme

Quickly apply non-destructive matting and keying functions to your imagery, including chroma keying, alpha matte adjustments and alpha inpainting.

  • Non-destructively multiply or divide alpha channel information.
  • Easily use any layer non-destructively as a mask (without having to use Rasterise to Mask). This allows you to maintain external file links, for example with alpha render passes that might be TIFFs, PNGs or JPEGs.
  • Quickly extract white backgrounds from images. This can be used as part of a batch job to speed up background extraction tasks.
  • Chroma keying (e.g. green screen key) with configurable tolerance, matte spill and antialiasing.
  • Rasterise and inpaint alpha information, e.g. filling out empty areas after straightening a photograph's horizon.
  • Fine tune, clamp and smooth alpha matting on a mask or a layer's alpha channel.
  • Luma keying with configurable tolerance, good for blending composite effect layers.
