  1. Hi, I start with with the procedural texture ( Filters> Colours> Procedural texture) It 's in Lab mode , ( I wanted see LCH if s the easiest way to " move" w color ), Before, I made an simple test. in 1.8 beta, play with channel save as a preset, close the file An reload with another test file BUT By default we have RVB option, sometimes very difficult to reload it , and impossible with live filter option I can export the preset, but I want re import, photo (beta and release) say me Sometimes I have difficulties for found Lab option, perhaps by bad understanding of the structure Preset manager can you say me labcolor1.aftoolpresets
  2. Hi Callum I reinstalled The beta, now the preset are in the good directory But always, The preset generate by beta is not recognize by Affinity Photo beta or release if I test export / import. (internal error syntaxe? At this time , the windows have no mixing mode LAB equation only with lab mode selected , I am on Win10
  3. HI RC-R thank for reply, and for your Job on this forum , By default , it' s not active not exactly no function, i m said me. But if you are on L*a*b* mode you can try, for see. I try first the filter> option and see after the live option. Here I can't access in L*a*b* ? Perhaps, you have Right. Callum 2 try => Error?, Callum you have right, but impossible make a reset to empty. Succes for made a new I see after the Video of James Ritson. In his video for each expression he use ; as seperator,alsi I said me , perhaps a error int the syntaxe, but i put comma , No action! Where is stored , in programme for delete the file or... I have always error with import, Okay , I can't export / Import but the preset is Okay...
  4. I think you speak about Quick Mask see the Help F1 Extract : " To edit a selection using Quick Mask mode: Do one of the following: Press Q. On the Toolbar, click Quick Mask. From the Select menu, select Edit Selection As Layer. Click or drag on the page using any pixel-editing tool. Repeat step 1 to exit Quick Mask mode and display the selection as a marquee."
  5. PLEASE when we use the Blend Ranges gives us an option with L layer (L*a*b*) for me it's more logic, more precise for the usual usage...
  6. OK thank Alfred understand One solution juste mine open this file 1614.afphoto I made a B&W extract off the Color layer, I select the sky with Threshold ajustment ( more faster in my case ) Merge B&W with This Threshold obtain a layer Drag it on duplicate Background layer (Original color version) I obtain a layer with a Kind of mask, this layer have internal properties, in this layer you can make any adjustment local Protection against global adjustment as long as it remains in this layer or is not isolated by a Group
  7. Hi Harvey You forgot send the files
  8. HI MEB, Here Is the file . LAB_schematic.afphoto Thank to you
  9. I made an example See the file clik on the invert adjustment select deselect Select give random squares on the screen LAB_schematicBUG.zip
  10. I am on Win10 not on Mac Lab mode.. same problem, random no use with group or live filter. Not only with this last version, the random square finish by disappear another click. This square is so typical I think that a developer should quickly find, this reminds me of an internal treatment square by square ? ...!
  11. Sometimes, I’ve had squares without groups, in your example, the squares came when I wanted to explore procedural texture that you use ; by the way, thanks for this example, maybe a solution for a problem, or an evolution , not so easy.The documentation is summarised.
  12. I observe this comportement, without understanding the relation with my process, One or more square parts in the picture. I didn’t understand and it seemed a bit random to me.

    Dodge Tool Doesn't work

    Just see it, for me mouse drag work fine (Ray S instruction) the new brush trace makes the efffect more intuitive in this case
  14. found this topic Dave with >|< citation Found also this video Dave I think, https://www.youtube.com/watch?v=B5F4hkUVttE go to 4:21.
  15. Ok, thank for this answer IPv6, Impossible for me compare with photoshop, desactivate it .
  16. Hi, I'm on windows10 !. Perhaps In this case, no problem, the channel mixer react well If i select channel BOpp by example... If select another a*, or L* , on the same flow , I must reset To facilitate the adjustement i have print this link https://www.handprint.com/HP/WCL/CIELAB.pdf, navigation with 2 parameter as a complex number Perhaps If start with Lightness (L*) and use the Ao (a*) slider affect at this panel no good action in this case Ao and Bo slider but for me it' s make no sens !, first i change color on color layer and second , after, i adjust the Lightness of the color . brightness L * only represents the absence of light (surface reflectance) and not the black colour, often misunderstood for me ... notion of reflectance of light correct for one color;
  17. Thank you for decrypting, very informative I just found out Some things have already evolved, or been clarified thank you for all of your time and effort
  18. Big thank Just at 3:09 for applied the gaussian blur on the vector rectangle. OK with 1.6. For the 1.7 Beta, I must do, before rasterize and trim (I m' not exactly understand the item) Nice job, your worflow, give me a flexible way, which is very often required for adequat correction
  19. I come back on this post, the first time I had not understood the subtlety... Concerning the layer M intended to realize the future mask, it is more precise to do it according to the layer L * without colorimetric interference therefore go (Channels, clear A clear BOpponoent). After Duplicate It is possible to invert with ctrl I, subtract, in fact obtain real masks of luminance in 16 bit Remenber : L * = white (L +) vs "black" (L = 0) a * = red (a +) vs green (a-) b * = yellow (b +) vs blue (b-) more... It is possible to create a modulation of transparency (alpha) according to the opposite colors (red, green, yellow, blue ...) mixte with evenutally the luminance.. very powerful

    Subtle Sharpening

    fine, not agressive, tested on pictures with many elements, it allows to bring out certain details, including colorically with subtlety Thank

    Saturate a photo using subtract mode

    @ john sorry , english is not so evident for me. I try the macro with only one background layer, I send you the file. 1.7 Version I hope it's good. Say me if you want a 1.6 version. usually modulate opacity on the color layer or the duplicate is enough. L layer with curves for correct the global images or part must be use in some cases.s @Hanshab, it's ok for me and I understand your comment. John.afphoto

    Saturate a photo using subtract mode

    Hanshab, In a precedent thread about Saturation mask you have propose the Mode L*a*b* for this. This message incitate me to explore it, as you said at this time, it's more easy more logic My 1.7 macro lab Lab .afmacros Process use I tried The image of John Click on the macro You have Luminance L and Color (ab) at this point nothing new compare with background desactivate this last one Duplicate color layer put in saturation mode and made groupe Multiply mode adapt with opacity, Big effect.. eventually use Luminance layer curve , here not use perhaps local correction on over lumonosity on white inflorescence, here white is not color) here not use perhaps local correction for the "over luminosity" on white inflorescence , here white is not color

    LAB color Lightness decoupling and use

    here is my file Lab 2.odt with the good link. I see my pdf have some problem about it...
  24. Hi, I write few pages about L*a*b* worflow for trying promote this space about decoupling Color & Lightness in L*a*b* here Lab.pdf this macros is on 1.7 version , not compatible with 1.6 Lab.afmacros Just read this answer Nothing new reinvent the wheel... But perhaps, some one, may have better understanding of this color space and more easy color apprehension, more easy color manipulation Sorry for my bad english, not my maternel language Have fun
