What to do if automatic removal of background in PhotoScissors didn't produce a satisfying result? Usually this happens when the foreground object and the background have the same or similar color gamma. In this case automatic algorithms of PhotoScissors simply cannot effectively distinguish the backstage from the central figure. Hence the final result may look inaccurate, with ragged boundaries, or you can see leftovers of the background that the program mistook for parts of the foreground object.
Don't fill upset though, there's still an easy solution. You just need to help the program a bit and edit the background and foreground masks manually.
With red and green markers paint a few rough strokes to indicate the background and the foreground areas. PhotoScissor automatically cuts out the foreground object as you do and displays the result in the right window.
Keep adding green or red marks until you see the result that feels good for you. However, sometimes you cannot acheive satisfying results using the automated procedure. In this case you need to switch to the manual mode using the M button on the left toolbar.
Here, the automatic algorithm detected the bottom left corner as a part of the foreground image, which is not so. So we enable the Manual mode and explicitly tell the program to exclude this part of the image:
Excellent! Now the result is just what we want it to be. As you see, manual presision editing of the photo background is easy enough with PhotoScissors.
The right toolbar contains settings of the background and foreground. They include "Smooth the Boundary", "Offset the Boundary", "Feathering Radius" and "Effect". Combined, they allow you to polish the final result and produce spectacular artistic impression. Read more about applying effects to photos here. And this tutorial explains how to use the above options.
