  1. As far as I know (might be outdated) you can create LUTs by 2 methods:

    1. add several adjustments on top of a base image, then export LUT
    2. infer LUT by comparing the current opened image with another external file

    i‘be never seen exporting a LUT directly from RAW edits.

  2. When I have good daylight, I set exposure to 1/2000 to avoid any motion blur, or even manual 1/2000 and aperture 1/8 for sharpness and consistency between shots, and let the iso chosen by camera to get proper exposure.

    When developing in Affinity Photo, keep the RAW files as flat as possible (no denoise, not sharping). You may do some basic denoise.

    Then develop and do the rest of editing in Photo Persona.

    This allows to treat blue sky and bird totally different. Use a good mask (take your time, may use pen tool to create a perfect vector mask).

    • sky: denoise heavy, but to not sharpen. Inpaint distracting areas like lens flare, distant birds, etc

     

    • bird: denoise only mildly, and use blend range to limit on lighter pixels. Try which sharpening works best, e.g. unsharp mask, highpass filter
    • try using tone map with local contrast (again on birds only) to really bring out details.

    For shooting:

    take a series of test shots to check if image stabilization (of lens and/or camera) actually helps or not. You. May get sharper images at 1/2000 when IS is off.

  3. both images look identical (as uploaded to the forum, rendered with Safari).

    We would need some more context in which app you see color differences.

    If I export to jpg the Cours stay very good, however expecting to weep seems to cause a drastic difference (less red) even though the colour loos fine in the preview.

     

    This sentence looks garbled. Did you mean:

    If I export to JPG the colors stay very good (observed in what app?), however exporting to WEBP seems to cause a drastic difference (less red) (in what app?) even though the colour look fine in the preview (of what app?)

  4. There are many ways:

    • create a rectangular shape, and nest it into masking position of the bitmap layer (drag and hold rectangle layer in layer stack, let go at the thumbnail of the bitmap layer). Rectangle can be resized any time to adjust crop.
    • optional: rasterize and trim 
    • use the rectangle as parent layer, and move bitmap layer into child position. Caution: resizing the rectangle will resize the bitmap layer, unless you activate „lock children“
    •  

     

  5. Even simpler, in case you don‘t plan to manually edit the mask later (e.g. with brush):

    • add levels adjustment
    • click on the cog wheel symbol to access blend range settings. In the „destination“ area, click on the right node, and drag it down. This will restrict the levels to darker areas.

    So 2 steps instead of 8.

     

    Stepping this up further:

    •  you can edit the inherent mask of the adjustment layer and use blend ranges,
    • but a unfixed bug does not allow combining blend ranges and additional, separated mask layers
  6. Well, please consider:

    • some companies like camera vendors, Adobe, Apple, and a handful of independent software companies develop their own raw engines, or license some proprietary code from those. Adobe and Apple are big $$$ companies with virtually unlimited resources 
    • Affinity uses free software, LibRAW, with a few tweaks (for Canon CR3, now irrelevant). 
    • Any more questions?

    The only advantage of SerifRAW is ability to use linked/embedded RAW, and you can disable lens corrections which comes handy in exceptional cases. In almost all quality aspects, Serif RAW is inferior, to Apple RAW and Camera vendor RAW engines.

  7. Thanks @telemax, but I did not invented this trick. Still works in V2.

    more important:

    The setting in

    Have you tried switching “Dither Gradients” OFF in Preferences / Performance?
    See attached image for an example.

    In V2, it’s the same setting but in Settings rather than Preferences.

     

    Does only impact rendering in Affinity. If you export, the export will contain dithering! Even when this setting is off.

    and regarding the title you the thread:

    Dither is not noise. It only swaps positions of pixel colors, using the old color values which differ only slightly. In contrast to noise, it does not randomly change color values (it will never create „new“ color values not already in the file).
