Derevo Posted March 13, 2019 Posted March 13, 2019 Good morning, I tried to cut a product. So I used the brush-tool (above the magic wand) and clicked on the product, than I clicked on "refine selection" (German: Auswahl verfeinern). But now there are ugly black stains around the product and it looks "dirty" on the borders. Just did it like in the tutorial on youtube. What am I doing wrong? the former background was a lit grey/white. But I want it on the white background. Quote
firstdefence Posted March 13, 2019 Posted March 13, 2019 Much better off using the pen tool for accurate selections. once you have drawn the curve you can convert it to a selection Derevo 1 Quote iMac 27" 2019 Sequoia 15.0 (24A335), iMac 27" Affinity Designer, Photo & Publisher V1 & V2, Adobe, Inkscape, Vectorstyler, Blender, C4D, Sketchup + more...

I agree with firstdefence, but if you want to use brushes you can fix the mask with them as well. The 'dirty' bits you see are due to feathering - AP calls it Hardness - when you create your mask. You can examine your mask by Alt- or Option-clicking the mask's thumbnail. When you do, you'll see some parts of your mask are gray - these are what is causing the problem. You can use your brush to edit the mask directly or you can return to your image (click on another layer, but DON'T forget to click on the mask's thumbnail again so you're editing the mask rather than whatever you clicked on) and edit there. Viewing the mask directly really helps to understand what's going on. It also allows you to make sure that all the areas you want to fully reveal are painted solid white and those you want to fully conceal are painted solid black. One other handy mask trick. You can Ctrl-Click on a mask's thumbnail to convert the mask to a selection. Once you do that, you can save the selection to a channel (Select/Save Selection/As Space Channel). Although you've saved a selection, which I always envision as a hard edge, the channel contains all of the semi-transparent sections (like feathering) as well. Once saved to a channel you can load it to the Pixel Selection channel for whatever you've got active (like another mask) allowing you to load/save and later refine the mask. If you do this, don't forget to name the selection channel! Quote Windows 11 Pro, XP-Pen Deco 03, AP, AD & APub
