Re: Advanced High-Pass Sharpening

using the blend if sliders is not the same as using the threshold slider in usm.

Re: Advanced High-Pass Sharpening

- SHARPENING: UNSHARP MASK -
Threshold sets the minimum brightness change that will be sharpened. This is equivalent to clipping off the darkest non-black pixel levels in the unsharp mask. The threshold setting can be used to sharpen more pronounced edges, while leaving more subtle edges untouched. This is especially useful to avoid amplifying noise, or to sharpen an eye lash without also roughening the texture of skin.
_______________________________________________________________

"Blend if" blocks the brightness or darkness, and only applys to where you want it too.

I think its just a lot easyer to use and is designed to do a specific task. As aposed to blend if, you have to work with it to get it right.

For those of you who have Pixel Genius plugins, there is a high-pass sharpening as one of the automated sharpening options.

The command flattens what it does into a single layer, but watching it flash quickly as it works, there are levels and photo filter layers involved.

I don't want to use automated commands and would much rather know how to do it manually.

Anyone know the steps?
I am relatively new to the site and would like to introduce myself by putting in my penny's worth. To sharpen an image with the high pass filter is not difficult. 1. Duplicate the layer of the image you want to sharpen. 2. Make sure that the duplicated layer is active and go to Filter>Other>High Pass.The highlighted layer turns gray. Move the Radius slider not more than 4 and click okay. 3. Change the blend mode of the highlighted layer to overlay and you've got the image sharpened.

Re: Advanced High-Pass Sharpening

That's for the input guys, I'll try the two layers with the blend if sliders, that seems to be the key.

Volare, like most filters, the straightforward approach is only the beginning. I think most of us know about High-pass set to overlay mode, but there is always room to go much further than that.
