Thread: Smart Sharpen Tutorial : Warning, huge image links.

    Default Smart Sharpen Tutorial : Warning, huge image links.

    Was at the library the other day, and happen to come across an excellent photo retouching book by a famous photographer cum photoshop guru Katrin Eismann.

    The Book is titled "Photoshop Restoration & Retouching" published by Que Publishing.

    Came across this excellent sharpening tutorial which is really good for those who're often plague by the "over-sharpening" unsharp mask syndrom.

    I've used a picture i took the other day, not an excellent photo, but it's mainly just for reference.

    Without further ado, let's begin.
    (Tutorial extracted from book, for those fortunate enough to loan it, its located at Chapter 8, Page 191)

    Step 1:
    Open your selected image in Photoshop, and duplicate it once.
    Go to your channels and duplicate the channel with the highest image contrast.
    Here i duplicated the Blue Channel which is usually the one with the highest contrast.

    Step 2:
    Select filter -> stylize -> find edges.

    Step 3:
    Invert the channel , (Ctrl + I)

    Step 4:
    Select filter -> noise -> median and use a value of 2 to accentuate the edge lines.

    Step 5:
    Select filter -> other -> maximum and use a value of 4 to spread the edge lines even more.

    Step 6:
    Select filter -> blur -> gaussian blur and apply a value of 4.

    Step 7:
    Return to the composite view , (Ctrl + ~) in the channels palette and load the channel mask, (Ctrl + Alt + 4)

    Apply the unsharp mask filter to sharpen just the edges of the subject while avoiding sharpening noise and grain.
    Settings may vary. Just use whatever settins that suits you.

    tried it with a macro shot, didn't really see any difference even when i increased the percentage amount of usm.

    Did you previously USM your image?
    It's actually quite a subtle yet effective sharpening effect.
    Can show me the before and after image?

    btw, its not just the percentage, the radius and threshold plays a part too.

    If there's no difference, you might have missed a step or did some mistake.

    Seen this one? Most smart sharpening methods are usually variants of this one. If you want a fully automated version, try Fred Miranda's FM intellisharpen or edge sharpen pro on his website : http://www.fredmiranda.com/

    Yes I had to buy Fred's actions, but if you are into a lot of image editing and processing, believe me, this is one action you will love, and use all the time. I have no regrets buying it.
