PhotoShop has some basic sharpening tools, and I used them to a small degree. What I didn't know was that a completely different technique could also be used to achieve a sharpening effect. The alternative approach works with a copy of the original, which then has a High Pass filter applied. The art to this technique is knowing how much Radius to give the filter. This one was given around three pixels. The result is a grey wash. But if you use a Hard Light layer option on that High Pass processed layer, the result is striking -- way better (or at least easier) than traditional sharpening.
A Mark Twain quote comes to mind:
The difference between the almost right word & the right word is really a large matter--it's the difference between the lightning bug and the lightning.I guess the same thing can be said about the right PhotoShop technique too.
