I think you can use Linear Light in Affinity Photo to create the same effect as Grain Merge in GIMP. Not sure, but I also think that Pin Light will simulate GIMP's Grain Extract. Biff

Great Tutorial. Thanks. Biff

Hello, People. Don't forget the Help files: these are very extensive and detailed. Don't know why Affinity haven't published them (maybe as a downloadable PDF)?? Biff PS: there's a hint in there somewhere.

Thanks, R C-R. Guess I should have checked the Tutorial Videos first. Panic set in, I suppose. Foolish Biff

Hello. I recently updated my Mac OS to Mojave (10.14.4). I have now found that I can't access Nik Color Efex or Analog Efex, although I had no problems with 10.13 (High Sierra?). As shown in the attached screen-shot of the Affinity Photo Preferences dialog, both these plug-ins require "Global Support". I have, as can be seen, tried a few variations using the "Authorise Global" button, but to no avail. Any help? Cheers, Alex

Well, there's a novel idea. Hope they do well. Biff

Nice macro. Imported fine. Changed the Gausian Blur to a Median Blur. A bit different, perhaps. Biff

Hi. I got the same response when I transferred the files from my old MacBook to a new one. However, I had kept the downloaded installation files, so I deleted the NIK files and ran the installer. All was well. Biff

Sorry to butt-in here, but have you tried converting your RAW files to DNG? I think Adobe's DNG converter is a free download, and is updated on a regular basis. Regards, Biff

Can I bump this?

Thought this was already available, but it seems I mis-remembered. It is available in Silver Efex (of the Nik Collection). There is also something similar in Lightzone (note: LightZONE not Lightroom). I feel it would be a useful addition to Affinity Photo. Keep up the good work, Biff

A very interesting, and informative, video. I look forward to seeing the use of Gradient Maps in B&W conversion. There is, of course, a further method for converting to B&W - the use of B&W LUT's (Look Up Tables), especially for Film Simulation. See for more information. Regards, Biff

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

Came across this youTube presentation which may be of some interest: Regards, Biff
