As a long standing user of PhotoPlus, I have found a lot to like in Affinity. For example * Smart, clean appearance of the UI * Flexible implementation of layers and masking * All the tools I am used to are there, along with quite a lot more * In the main, evrything I have tried works smoothly and reliably. My first impression is that this is astonishingly good value for money. On the other hand, I have a few gripes about the software as it currently stands: * It installs without apparent problem on my Windows 10 system, but there seems to be some glitch with file associations, because when I right-click on an image file in the File Explorer, I get an option to open the file with PhotoPlus (and others), but not Affinity Photo. Strangely, though, I have succeeded in setting it as my default program for .jpgs. * I have some problems with brush tools, namely (i) there is some slight lag in the effects appearing in the image (I think this has been noted by others, and it is perhaps better in the latest update); (ii) when I move a brush across an image without holding a mouse button down, the disc showing a preview lags considerably behind the outline of the brush, which is quite disconcerting; (iii) when I move the cursor to the toolbar ro adjust brush properties, it correctly turns to an arrow, but when I return to the image, I don't get the brush back again until I click. * The Perspective tool doesn't have (or, at least, I can't find it) the option I need for changing perspective, namely a mirror motion of handles at the two ends of an edge. I think it is a bit awkward that the available transformations are split between the Perspective and Move tools; it would be more convenient to havd access to all of them at the same time. * Undo and Redo buttons would be handy, though I appreciate that there are both a menu item and a keyboard shortcut. * For merging layers, the Flatten option appears in the Document menu, and Merge Selected appears in the Layer menu, but neither appears in the right-click context menu in the layers pane, although Merge Down and Merge Visible do. It would be handy to have all these options in the right-click menu. * Most importantly, for me, it isn't possible to invoke the Topaz Remask plugin. From a couple of other posts, it looks as if there are no plans to fix this, and as I noted in a reply, this is a serious disadvantage for me. One other observation: I tried to compensate for uneven lighting in an image by using a Brightness/Contrast layer with a gradient fill in the mask. It proved possible to adjust both the Brightness/Contrast sliders and the gradient fill at the same time. I found this extremely useful - but I'm not sure that this was intended by the programmers, because the fill eventually becomes rasterized. It would be nice to have the parameters of the gradient fill remain permanently adjustable.
