    Question Sharp edges in Photoshop.

    Just wanted to ask everyone's opinion on this one.

    I currently know only 3 ways of making sharp edges in photoshop, none of which seem efficient to me, is this normal?

    1. Selection marquee: marquee + paint inside or outside of the edge. Disadvantage: takes time to make the selection (especially for compliacted shapes), or when you need to make some changes to an edge made earlier (unless you keep a million alpha channels).

    2. Sharpen tool: sharpens the whole underlaying image. Disadvantage: hard to gauge right, often gives a synthetic-like feeling.

    3. Brush properties: Turning wet edges on and turning opacity sensitivity off. Disadvantage makes the brush very opaque, so it's hard to get it to look right, especially when making hard edges in the final stages of a fully renderd piece.

    These are my current observations. I see a lot of people getting these edges right off the bat in the Chow's and Eow's, my wips and finished pieces are almost always blurry so maybe It's just my experience level, or maybe i'm doing something wrong.

    Here is a recent photo study:

    Pencil tool. Works like brush tool, except none of the anti-aliasing, so you can get absolute pixel precision with it. You can't get any harder edge than that. It's surprisingly under-utilized.

    use un-sharp mask filter, not the sharpen tool, then mask out areas that you want less sharp. Careful not to go over board with sharpening though, it can give a bit of a harsh digital look imo.

    Yep I think what you want is the pencil tool; just use it for very sharp shapes and refine/smooth with your regular brush.

    About the unsharp-mask, that's not a good idea ( same for sharpen ) because it adds unwanted colors at the edges detected.
    Try to copy your whole image, convert to a clean black and white, apply a High-pass filter and change its layer mode to "linear light" then play with opacity or mask values.
