  1. I'd like to "Bump" this topic - I've started using a Panasonic G7. Can I extract the JPEG frames from a 4K video? Cheers, Biff
  2. Exactly the same as me. I did work around this vey extending Smadell's Luminosity Selection Macro's after I had figured out the maths. I took them down to Lights 6, Darks 6 and Midtones 6. In theory these selections should be the same as the more "traditional" method.
  3. You could try DFine from the Nik Collection, although I'm not sure the 'free' version is available anymore. It can be accessed as a plug-in from Affinity Photo (instructions are somewhere in the forums ...) Biff
  4. In the land of the Eucalyptus, I guess it makes some sense. Three quarters of all forests in Australia are Eucalyptus - there are some 810 recognised species. If you see a tree in Australia, chances are it's a Eucalyptus, even if it doesn't look like one.
  5. I suspect Mark is trying to do what I'm attempting: a Macro for making Luminosity Masks (Lights, Darks & Midtone). I can't rename the Spare Channels from within the Macro. So I would like to "bump" this request. Biff
  6. I had this 'problem' on my MacBook with version 1.6 and it seems to have carried over into 1.7. Not a major problem, but ..... I use the Trackpad on the Macbook, and normally this behaves like a Mouse: the two modifier keys ('control' and 'option') acting as left and right mouse buttons (Mac Mice tend not to have these buttons anyway - these modifier keys are used). However, in the Channels Panel, these modifier keys don't work - I need to attach a mouse with left and right mouse buttons!! Seems to be only place this happens. Regards, Alex
  7. 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
  8. 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
  9. 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.
  10. 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
  11. 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.
  12. Thanks, R C-R. Guess I should have checked the Tutorial Videos first. Panic set in, I suppose. Foolish Biff
  13. 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
  14. Nice macro. Imported fine. Changed the Gausian Blur to a Median Blur. A bit different, perhaps. Biff
  15. 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
  16. 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
  17. 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
  18. 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
  19. 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
  20. 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
