Quick Selection, sharpness possible

Question

Hi,
I'm using Adobe Photoshop CS3, is it possible to have sharp selection using quick selection tool.
I'm doing cut outs for feature pages and I use pen tool often  which give sharp edges, but is the same possible with Quick Selection ?

Answer 1

That you're asking this question implies you may not have a solid understanding of path vs. pixel (raster) selection and masking operations.  Given that it's hard to judge that, it becomes a bit difficult to answer your question well.
Perhaps if you describe more about what you're currently doing an answer will become more clear.  Are you making paths with the pen, then turning them into selections, then copying image data using those selections and pasting it into another document?
As an attempt at a general answer:  The quick selection tool by itself doesn't make generally sharp, straight, clean edges and kind of expects you to do edge refinement on its selection to make a mask.  Note, for example, the [Refine Edge] button available when the quick selection tool is active.  Given this knowledge, it's possible you could do something like this:
1.  Quick Selection tool to generally isolate your subject from the background.
2.  Click the Refine Edge button.
3.  Adjust Contrast and Smoothness to isolate the subject with sharp, clean edges.
There is incredible power in the Refine Edge function, and it's well worth looking into further.
There's a decent Russell Brown video tutorial on masking and refining edges here:

Hope this helps!
