RodBoffin Posted April 19, 2016 Share Posted April 19, 2016 I have found that Affinity Photo does not always give a high quality edge mask and this would be improved by shrinking the mask AFP has created by shrinking it, is there a means already available that would allow this? I searched and could not find any way to effect this. I noted also that the Feather seems to work on the outside of the mask edge, whereas if there is no way to define whether the mask is feathered from inside or outside the edge, it would be better defaulted to the centre rather than the outside, which currently means part of the background is allowed through which rarely ideal. I feel that when using the image to define where the mask falls needs the ability to be resized to suit where the feather is made. Currently working from high resolution images where the Web is the end result AFP works acceptably, but that is not the case for work appearing in Print. Unless as I mentioned I simply have not yet found your means of resizing the mask. Quote Link to comment Share on other sites More sharing options...
barninga Posted April 19, 2016 Share Posted April 19, 2016 the refine selection dialog has a ramp cursor, it ha the effect of shrinking or expanding the selection edge, did you try it? Quote take care, stefano Link to comment Share on other sites More sharing options...
RodBoffin Posted April 21, 2016 Author Share Posted April 21, 2016 Hi baminga, Yes, I tried that, and absolutely nothing happened. I keep going back and recreating the initial mask and try different parameters and so far I do not get a good edge. I will however try using paths and see where the feather appears, because my belief is the problem starts there, and I mentioned that in my initial posting. In my book a feather should always be centred upon the original edge thereby blending a proportion of each image layer, and this is primary why a single pixel feather seems a constant for creating a believable edge. I want this program to succeed as I am impressed with how far it has gone to date, and believe the impetus exists to make it. I cannot get back to it just now due to other activities, but as soon as I can, I will. Quote Link to comment Share on other sites More sharing options...

barninga Posted April 21, 2016 Share Posted April 21, 2016 in my experience, the ramp control (found in the refine selection dialog window), applied to an existing selection, does shrink or enlarge the selection. not by a dramatic ratio, but enough (again, in my experience) to have the selection edge following closer the border of the selected border.

R C-R Posted April 21, 2016 Share Posted April 21, 2016 According to the video tutorial, the ramp control is in effect a tolerance setting, but I'm not sure exactly what that means in terms of how it affects edge detection or whatever it is that the "Refine" selection algorithm does that changes the size of the selection. It perhaps should be noted that for "hard" (perimetric) size or feather changes, options are available separately from the Select menu as Grow/Shrink & Feather, respectively, along with Smooth. They act more like the "dumb" (non-adaptive) controls found in other apps.

crabtrem Posted April 21, 2016 Share Posted April 21, 2016 I have had good results varying the border width selection. That in combination with the ramp tool usually gives me the results I can live with. One other thing that I find many people overlook is that the refine selection brush has options for painting matte, foreground, background, and feather. All good limiters for different refining situations. For me, I find it better to start by refining the background first, and then either matte or foreground.

cadobir Posted April 22, 2016 Share Posted April 22, 2016 Another approach is to go into quick mask mode, blur your mask, and use Levels to refine your selection. I don't think AP offers a Maximum/Minimum filter yet. Quote Link to comment Share on other sites More sharing options...
barninga Posted April 22, 2016 Share Posted April 22, 2016 under the filters->blur menu, there is a "minimum filter" and a "maximum filter". they work destructively. Quote take care, stefano Link to comment Share on other sites More sharing options...
