    Thanks for the reply, stokerg. Having just applied the technique to a fairly high dynamic range photo, I must agree. I'm not sure on the how or why it works, but the highlight recovery (sky) showed that it works. However, I find that I need to change the colour format back to 16 bit RGB after the Tone mapping stage, otherwise everything's can go horribly wrong in the Photo persona (must have something to do with the linear response to curve adjustments in 32 bit). Regards, Biff

    Good Morning. A couple of us (Affinity Photo users) have asked this question on the youTube presentation "HDR from one exposure" (https://www.youtube.com/watch?v=Ar6CZvfyFvk&feature=youtu.be). In the video, the Develop Persona is set to 32-bit. However, as a single RAW file has only 12-14 bit depth, why are you setting the bit depth to 32 bit? Regards, Biff

    Probably needs an other bump .... It's a good idea, and the tutorial video is great.

    You could reapply the Frequency Separation to the Low Frequency layer (residuals) several times, with a higher radius each time. For example, the first application could be at 2px, a second at 4px, a third at 8px etc for as many passes as you require. The High Frequency layers are all blended with Linear Light (the same as Grain Merge in GIMP), and can be treated the same. I tried Pat David's GIMP tutorials using Affinity and it seems to work. It could be automated with a macro, but I can't figure out a way of passing parameters - I would need a starting radius and a increase factor. Such fun, Biff

    Something I've just come across - ON1 Effects 10.5 is now free (sorry if this old news). https://www.on1.com/free/ It comes with plug-ins for Photoshop, Lightroom etc. Unfortunately I haven't been able to get the Photoshop plug-in to with Affinity Photo. Any ideas?? Regards, Biff

    I'd like to add to this suggestion - that the Histogram is shown in the Curves graph (as is shown in Curves Adjustment tool in Photo the persona). Regards, Biff
