I am a relativity new user to Affinity Photo.
I have included five files. 1 the Affinity Photo file and 4 jpg images for figures I refer to in the following.
I am developing a series of flower pictured that include some complex mask. I am defining the mask using the tool under the Refine Selection. The workflow is to make the initial selection of the flowers using the Selection Brush Tool. Once the initial selection is completed, I press the “Refine…” button. I continue using the using the Adjustment Brush in the Refine Selection dialog box. I have not adjusted the setting in this dialog, and I am using the default values. I complete the second refinement using the Overlay Preview. I then switch to the Black matte and that is when the “Ghost Images,” as I call them, appear. See Figure 1, first jpg image, “Fig 1 Ghost Images [date and time].jpg.” I carefully remove these Ghosts by adjusting the cursor size and by try not to let the cursor touch the part of the image I want to keep in the Foreground. After I lift the mouse button and the refine selection computations are completed, the selected Ghost Images is usually removed, but others will appear or reappear in other areas of the image. Most, but not all, of the Ghost Images appear to be a bleed through of parts of the image in the background, See Figure 2 in “Fig 2 More Ghost Images [date and time].jpg” The areas shown in all of these figures have repaired many times.
The area shown in Figure 3 in “Fig 3 Major Problem area [date and time].jpg” is one of the worst areas and has been repaired, and repaired, and repaired….
One several occupations, the computer went into a very long computation period. I first though the system had lockup, but it eventually it completed the computation. Once completed, all the selections were lost, and only the base image appeared. The “Selection Brush Tool” had been turned off. I pressed the selection tool and the computer went into another long computation period and was able to recover most, but not all of the previous selections. A large amount of the most recent changes was lost and had to be repeated.
Another aspect of these problems is my inability to get crisp and sharp edges. Figure 4, “Fig 4 Areas with Difficult edges [date and time].jpg” show an area where getting a good sharp edge is nearly impossible.
This problem does not appear to be an “one of” problem. I have completed 47 images so far. The problems, describe above, have occurred during most of the selection and refinement process. The problem is worst on images with the more complex masks. Also, the longer I work on an image, the worst the problem becomes. On several occasions, I abandon the problem image and started over. The restart seamed to work better. But again, the longer I worked on an image the worse the problem became.
The dialog Refine Selection Dialog box has several settings that I do not understand. The settings I am using are shown in Figure 1 and are the default settings. I do not understand what these setting do. Can adjusting the settings in the Refine Selection dialog box help?
I would like any suggestions on how I can eliminate this problem or a least minimize it.
