In addition to the stacking functionality, version 1.9 also introduces a dedicated Remove Background filter for astrophotography, which can be used to tackle difficult background gradients or simply neutralise a background colour.

Let me run through a few common workflows and how you can use Affinity Photo’s tools to achieve them: Removing difficult background tones The Orion Nebula, processed from a one shot colour setup using various adjustments and live filters.Īffinity Photo includes a variety of tools that work well with astrophotography retouching techniques. Retouching tools, selection tools and blending options

If you’re completely new to astrophotography post production, Affinity Photo is definitely not a bad choice for keeping things straightforward and manageable whilst you learn the stacking process.Īdditionally, the whole process is documented in the Help-available offline through the app and online at. Save and load bad pixel map presets so you can easily re-use them for future data.

Bad pixel map tool: alter the threshold for determining hot and cold pixels from the calibration frames, and also manually add bad pixels and column defects to the bad pixel map.

Light frame analysis to select a percentage of best light frames-good for rejecting frames with star trailing or poor focus.

Setting white balance based on daylight (D65), the image metadata or inferring it from the master flat (applicable for one shot colour workflows).

Choosing between Affinity Photo’s bespoke demosaicing (sharper, fewer false colour artefacts) or a Bilinear implementation.

Manually setting the FITs/RAW bayer pattern.

Configurable background calibration to normalise background values between each image.

File groups for stacking data from different sessions (that may require different dark and flat frames).

Stacking method: Sigma clipping with threshold/iterations, Average or Mean.

The Astrophotography Stack Persona: lean and straightforward.įor more advanced stacking, you have control over settings and additional tools such as: At its most basic level, you simply add your light frames and calibration frames using the Type dropdown, click Stack and then apply your stacked result to move back to the main Photo Persona (workspace), where you can work on your image further. The process of stacking your initial data along with calibration frames can be complex and also quite daunting for beginners.Īffinity Photo strikes a balance between offering enough customisable parameters for advanced users, yet keeping the interface lean and straightforward.

… the list goes on! In particular, Affinity Photo’s Procedural Texture filter allows you to achieve all kinds of additional functionality if you’re handy with mathematics, and it is, of course, available as a live filter so you can apply it non-destructively. Highlight brilliance (High Pass with a Hard Light blend mode).Mesh distortion and liquify effects (Liquify).Luminance and colour noise reduction (Denoise).Live star and background masking (Procedural Texture).Structure enhancement masked to just specific areas (Clarity).Star glow (Gaussian blur with Overlay blend mode and blend ranges/opacity).If you wanted to have a completely non-destructive layer stack where no layer merging is required, here are just a few techniques you could apply: Live Filters being used to apply star reduction and structure enhancement non-destructively.
