Unsharp Masking Techniques

[Andrew O'Neill]

A couple of years ago, someone outlined how they did unsharp masking. I cannot remember how it was done. It did not utilize only the unsharp mask filter. I remember that the blacks were somehow selected and then I believe they were sharpened with the unsharp mask filter...? I've searched for an hour, but cannot find that thread. Anybody have any ideas how to do this or which thread that info was in? Thank you.

I think what you are looking for are Luminosity Masks.

I guess you're talking about Photoshop, or digital unsharp masking?

To do it in the darkroom, I think you need pin registration gear, which is expensive and rare, not to mention a considerable amount of know-how and time.

Since he posted in the digital processing forum, yes .

Andrew, I read that thread as well but it hasn't popped up in a while.

Oops. (Open mouth, insert boot, thankyou may I have another) :o

I know all about unsharp masking in the darkroom and have done it for years. Frederick, nope not that. I use PS. Thanks.

You might be interested in using 'Filter - Other - High Pass' on a copy of the layer, then change the layer mode to 'Overlay'.
When making the filter, adjust the pixel radius to show subtle outlines.
You can adjust the layer's transparency to your taste, if necessary.

Andrew,

Is this the kind of technique you were interested in?

I found it by searching for "Photoshop sharpening." There were countless other techniques to sort through via that search if this isn't the right one.

I know, I spent ages sorting through many threads on the topic but not the one I wanted. I really should learn to be more organized. Since looking, I had no idea there were several ways to sharpen. No worries Cletus about putting your foot in your mouth... I've done that many times! Thanks for the help gentlemen. I appreciate it when people take the time to help.

My two... I found it works well when scanning negatives and slides and almost always use it when printing scanned negative images and digital today - exception some portraits. In PS: Filter, Sharpen, Unsharp mask, 100, 1, 5 basic settings. My PC monitor is not obviously an exact replica of print. Printing is the test.

RPNugent, that's the one! Thank you!

I've always done change mode to LAB select lightness layer and do sharpening there (supposedly less noise) then convert back to RGB mode.

I just tried the video's method on one of my files. Wow, it's great, and worth using.
