  1. @MaryLou, I used something like this to create a seamless image of leaf litter for the Friends of Coombe Wood website. I started with a square image of the woodland floor with full leaf cover. I then applied the Affine transform, with 50% shift. I then placed single leaves onto the main image covering the joins. Finally I reversed the Affine transform. The image was then faded to produce the final background image. The single leaf images were done by scanning the leaves on a flatbed scanner then removing the white background. Apologies for not updating this site, but I have not been able to get to the woods in recent months. John
  2. Thanks, @v_kyr. I looked in various menus, but never thought to look in Assistant. I have never used it to date, but have read about it in these forums. The capability of Affinity (and the forum members) never ceases to amaze me. But you do need to know where to look! John
  3. @carl123's suggestions worked, even without deleting the background layer as @v_kyr said. However I have now run into what is probably an unsurmountable problem. The procedure later continues with adding a live USM layer. This gets added to the current layer, but I need to move it. I am told by a pop-up that the macro recorder cannot record moves. I have looked to see if there are menu items that would help, but no luck there. I think that if I want to implement this edge mask - unsharp mask process, I shall have to do it manually. I was actually getting quite slick at it! John
  4. Thanks to @carl123, @v_kyr and @R C-R. I shall work my way through this advice and let you know how it goes. Just to confirm, by 'opaque', I meant 'opaque to my understanding'. Once I had @R C-R's explanations it all became pellucid! John
  5. I first duplicate the Background layer, then convert this new layer using Filter > Detect > Edges. I then add two adjustment layers, HSL to reduce the saturation to zero, then Levels to set the black and white points to 10% and 55%. This image is of the layers panel at this point: I then shift-click to select the top three layers: I then merge the three layers with Ctrl-Shift-E: Repeating this process with Macro Recording on, the first step looks the same: But when I try and select one of the other layers, I get: Depending on which layer is already selected, one of these options may not be greyed-out. As I said before, these options are opaque to me (whether greyed-out or not)! John
  6. When I get back to my desktop, I will see if I can take some screenshots both with and withour macro recording. John
  7. I understand that Smart Sharpen in PS is a form of the deconvolution algorithm. Are there any plans to add deconvolution to Affinity's arsenal? John
  8. Lightroom also has this feature. I would support it John
  9. I support @JayH's request. John
  10. I would support @JayH's request. I also find this re-sizing annoying. John
  11. I was trying to follow the tutorial from @MikaG on How to: Sharpening with Edge Masks from January 14th, 2016. This worked OK on a couple of trial images. I then tried to record his procedureas a macro. This involved merging three layers, the modified background layer and two adjustment layers. This worked fine in my macro-free trial, but would not work when recording as a macro. The message I get when trying to select one of these layers is quite opaque. I get the same message with each of the layers I seek to merge. Is selecting a layer in such circumstances a proscribed operation when recording macros? I note that @MikaG comments that: "Once the function of Actions is added to Affinity Photo it will become a task even faster". John
  12. The expression (w-x)*x/w/w should be zero at each end, rising to a maximum of 0.25 in the middle. Thus the arch should rise up a quarter of the current position above the x-axis (h-y). The a parameter at the default of 1 would have no effect. As a decreases, the value of the expression should rise in inverse proportion. It should do so strictly monotonically. It is not doing this on my Windows 10 PC. Note the 2* is just a fudge factor to make it behave as expected. (Note that strictly monotonic means that the rise should always be positive and non-zero.) John
  13. I take it that you mean that other software will not read the .afphoto format. As @Fixx says you need to export in a format such as .png, .tiff or .jpg. John
  14. Thanks, @stokergI will live in hope. John
  15. I believe that Affinity uses the IE engine to display some of its output. So, even if you do not use it, Affinity does. John
