  1. I think it's unhealthy to include a DAM in affinity!  Past experience with LR6 and  difficulties to evolve., update in time

    Seriff, a small company, already has to deal with its multi-OS suite.
    As far as I'm concerned, this company should concentrate on optimising the code for native functions and their updates.

    I don't want any additional 'glue'  NO DAM

    There's enough of that, as a standalone application, and some nice ones at that.

  2. More easy for me 

    16 bit for the precision 
      1 Make a provisional B&W version
      2 Use the pen tool to select the area on the forehead roughly to start and  use  a dynamic Gaussian blur for a smooth transition edge
      3 Use the dropper to select the right grey value and fill this area 
      4 Delete the B&W version
      5  Now switch the curve layer to divide mode (around  15 40% opacity  )  
        Adapt  the gray component if necessary with the color wheel  and perhaps the color with the peripheral circle a  little green ?..

    6 With the node retouch the limit on the area. 

    7 Review all dynamic parameters

    to retouch another area in this way, you need to make a copy of the initial layer and repeat this process

     

     

     

  3. Hi,

    sometimes there is objectively a bug

    I have the same problem since a while after an update, the plugin list disappeared, and impossible to reconfigure it?

     

    I just retried this morning  with gmic   all the proposed solutions 

             (like defining another folder, possibly on another disk with the right access permissions)

    It's repetitive if you look at the history of the different forums, in some cases certain configurations sometimes not all the time.

    Nothing!   On   APhoto V1
     

     

  4. It's to old solution

        A photo have now the divide mode. use it 

       Try this

    1. Fill layer whith dominant color, use the color picker
    2. mode divide
    3. play with opacity

    Okay ,

    this solution uses the entire surface of the layer  It may be wise to select an specific area,

    • use the Pen tools or an ellipse (no need for great precision) to select the area where you want to correct the color castand here fill with the dominant color. (adapt with gaussian  blur fx and with node )
    •  for the  gray /white component                                                                                                                                                                                                                                      fill with a neutral grey gray divide  mode ( color mode  adjusting saturation ) 

    The advantage of a vectorial object is that you can always adjust the color in situ.

    adjust witn opacity  at each step 

     

     

     

     

  5.   Hi smadell  

     

    I just tested your macros good job, cartoon effect but not only

     In the latest version of windows on the welcome image, we have a splash popup window, to give the password an interesting blurred version with color cast mapping.
     I was wondering how to generate this, attempt to use in color correction, just an instinctive reaction

    Your macros are perfectly usable and adjustable for this:

       On a landscape image, in hard  light*  mode and in neutral position 50% I obtained results which seem interesting in the spirit of Hwb.

      *or other light modes

    Yesss!

    Thank you

  6. Bonjour Piou

     Oui logique on assemble X calques en un seul calque

     Si tu veux  tout de même , garder l'opportunité de re intervenir  juste avant cette fusion

     tu dupliques en un groupe et ce nouveau groupe que tu fusionnes  en faisant clique droit tramer

     

    Yes, it is logical to merge X layers into a single layer

     If you want to keep the opportunity to intervene just before this merging   duplicate in a group and this new group, 

    you merge by right clicking on it rasterize

     

  7. Okay
    I understand Lavis
     one method for this dilute a color before using it use only one color
     that will be diluted to obtain different intensities of color
     
     We have a differential of appreciation in the term FILL, and an unsaid

    For me
    Fill Layers when  Need to add a layer that is completely filled with a solid color, gradient or pattern

     
     Go on youtube

    play with opacity colour overlay 
        I retained also that we could use semi-transparent colors on AFFINITY SWATCHES pantone Xxx
        easy
        
      Last video Colour overlay AFFINITY solid color  
     

     

  8. Smee Again i see your post , thank , if i understand you correctly

    For the Fill layer ( or Curve or vectoriel shape )

     it is  possible to use

    the Color>

    • Grayscale slider  more precise than color wheel
    • Or better for me Lab L 50 A 0 B0,  and move L plus or minus
    • HSL also

    To color layer  use these sliders with the appropriate mode, eventually add a mask to circumscribe the effect on the right area 

    No problem for a gradient

    I don't know if it does the job,  I have no PS

    I haven't found any explanation – as in: a mathematical formula – online yet. Everybody knows that the "Special 8" are there, "can" do this'n'that and they love it, but nobody tells you how exactly it works.

    But since it's all really just math:
    How about adjusting it in APh with a Procedural Texture live filter? Has anybody tried that?
    I'm no mathematician whatosever, so this is way beyond my expertize. But I noticed that @NotMyFault has recently experimented with Procedural Textures and seems to understand how it all works.

     

    Yees

    We can use procedural texture for this

    using vec4() for vector with 4 parameters

    here vec4(Rx,Gx,Bx, Opacity)

    Rx,Gx,Bx, Opacity, are define in [0.0,   1.0 ] For me no sens using 8 bit (Fill Layer is 8 bit!)

     

    First  Step we define

    vec4 c1 = vec4(0.0, 0.0, 0.0, 1.0); //Black

    vec4 c2 = vec4(1.0, 0.0, 0.0, 1.0); //Red

    vec4 c3 = vec4(1.0, 1.0, 0.0, 1.0); //Yellow

    vec4 c4 = vec4(0.0, 0.0, 1.0, 1.0); //Blue

    vec4 c6 = vec4(1.0, 1.0, 1.0, 1.0); //white

     

    we want an interpolation slider between White and Black

    var c1=vec4(0.0, 0.0, 0.0, 1.0);var c6 = vec4(1.0, 1.0, 1.0, 1.0); c6 * s + (1.0 - s) * c1

    image.png.7ffb25f0449b4ee9228a693ac4ccf917.png

    var for variable

                          c4 * s + (1.0 - s) * c1  // classic use for mixing or use lerp()

     

    And Yess, Pixel layer can gives same result, and with 16 bit!,

    32 bit is possible but my pc is limited 16 giga Ram , I5 and  and I am not convinced that it is better

     

    Rename each layer very important here, Otherwise photo can get lost in cyber space

     

    Turner-Shipreck.afphoto

    =>

    between Black and Blue

    var c1=vec4(0.0, 0.0, 0.0, 1.0); var c4 = vec4(0.0, 0.0, 1.0, 1.0); c4 * s + (1.0 - s) * c1

    between Black and Red

    var c1=vec4(0.0, 0.0, 0.0, 1.0);var c2 = vec4(1.0, 0.0, 0.0, 1.0); c2 * s + (1.0 - s) * c1

  10. Hi

    This reminds me of a colorcast mentioned on this forum about DX0 pureraw.

    In the meantime,

    I had read on a Darktable FAQ that this kind of problem (pink or blue color) was induced by screens which are not all able to translate fine variations of range in the highlights and that each software had its own way to deal with this limit
    From memory Aurélien Pierre advised to limit the range about 230

    On your histogram we can see that the high limit is largely exceeded, which should not be too hard to correct

    In Develop basic
                  Reduce the exposure a little
                  Decrease the brightness
                  Play with Shadows and Hightlight
                  Interactively
    First try
    to get close to the limit without exceeding it and conclude     the interaction with the 2 softs with your screen
    And tell us, please

     

     

  11. If I understand your request correctly  a solution i use
    Above the layer that received the gradient
            Put a fill layer with a deep black New Fill Layer
            group it  in erase mode

    modulate with opacity of the fill layer AND  the opacity of erase group

    The gradient doesn't move, it is just + or - Transparent

    I use for mixing with sweet modulation  (also for modulate luminance on grey layer, with local brush)

  12. Hi

     

    good start

    my suggestion

      Return to develop personna ,

    Play witf clarity =>  We quickly have a blue vertical bar,  never touch the right limit, it is the abyss

    you must go reduce exposition about -0.462.
        In this special case reducing the brightness and high light is not enough , normally its enough 
      Okay now go clarity 22% + or -
           Developp
      Duplicate background  put it in  soft light  reduce opacity about 60%
      That's all

     

    Sorry for my english, it's the principe, with  pratice, it' will be good.

  13. Hi,

    Also

     Since the last update,

    With raw (NEF),   we see losses of quality loss of sharpness, and tonality, if we compare with other viewer, as FSV, the decrease is noticeable
     If I go in editions preferences surprise! my GEFORCE 960 M card is not selectable anymore!
     By default, I have just the card, Intel by default, I can select WARP, but no more GEFORCE 960 M
           Win10, the open cl disabled, 16 g ram,
