  1. Affinity Photo (Desktop/Laptop) 1.7. I've downloaded the Lensfun database from Github (as explained in the YouTube tutorial video). I'm using a Samyang f/2.0 12mm NCS CS lens on a Panasonic G6. The lens is manual, but I'm using Exif Editor to add the lens data to the RAW file. Affinity Photo seems to recognise this, as the lens name appears in the EXIF data. However, no lens correction is applied (lens not recognised!). I have applied the exact same process when using my Samyang f3.5 7.5mm Fish-eye lens, and this is recognised for lens correction. I'm out of ideas! Regards, Biff

    Lensfun Fun

    Thanks for the replies, guys. As Woodkopf said, it was the James Ritson video (it is available on YouTube as well). In that video, James drags (or copies) the entire mil-sony.xml file to the Affinity Lens Profile Folder. In may case, I used the mil-sayang.xml file, which contains the correction data for both the Samyang f3.5 7.5mm Fish-eye and Samyang f/2.0 12mm NCS CS lenses (amongst others). As I said, only the correction profile for the Fish-eye seems to be recognised. Cheers, Biff

    Affinity Photo for MacOS - 1.7.0

    In App Store, go to 'Updates'. If it isn't showing, use Command-R (Cmd-R) and the Updates will update. Should be there by now.
  4. Useful technique. Thank you.
  5. 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
  6. 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.
  7. Thanks, R C-R. Guess I should have checked the Tutorial Videos first. Panic set in, I suppose. Foolish Biff
  8. 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
  9. Well, there's a novel idea. Hope they do well. Biff

    Watercolor & Ink Simulation

    Nice macro. Imported fine. Changed the Gausian Blur to a Median Blur. A bit different, perhaps. Biff
  11. 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

    Olympus HI RES raw files shot down Affinity

    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
  13. 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
  14. 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
  15. 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
  16. 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
  17. Came across this youTube presentation which may be of some interest: Regards, Biff
  18. Great stuff. Thanks for all the hard work.
  19. Great idea, and great tutorial. Thanks for the download ....
  20. Would be a nice addition ....
  21. 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

    Free ON1 Effects

    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
