Feather – This selecting menu option is useful for giving feather (Soft edges) to already drawn selection. This feather option can be given to any selection on the image and then soft edges will apply to existing selection. If feather value is not given to any selection before drawing on the image and we want to give feather to that selection then this option is very useful. If more feather value is given in pixels, then more softness will apply to the selection. This result can be seen after apply some operations like filling color, coping image to other image or location, applying mask etc.
Note: Remaining options will continue on next post.
For questions please comment.
Modify – Modify has four options (Border, Smooth, Expand and Contract). This option is useful for selection like Magic Wand Tool selection. Border split the selection border into two selections and gives feather. Smooth is useful for rounding for sharp corners and sharp corners of the selection will convert in rounded corners with given radius. Expand is used to spread more pixels with given pixel value with same shape of selection. Contract is used to reduce the size of the selection with given value of pixels.
