Default Local Contrast Enhancement

A very useful technique that I had almost forgotten. Check out http://www.luminous-landscape.com/tu...ancement.shtml this really works well to take a flat, low contrast image and turn it into an eye popper.

I use this quite often - I do two sharpening passes, one for fine details and then a second one for contrast. The second one, with a large pixel number and a small percent, really makes a difference. Thanks for linking to luminous Landscape - I hadn't realized this process was there - I learned it right here on this forum when Ben posted his processing techniques.

i've been using this forever..
i use A=10-20
T= 0
using 20,60,0 is where i started and it's usually the best but experiment.
using a hi-pass filter can do the same but it's a little harder to do..

Thanks for the link - it also contains another link to a very useful primer on sharpening:

Thanks Ira for providing this link.

I've never been much good at getting photo shop type programs to work or even been able to transfer my pictures to websites.

But my major project this winter is to work away and learn how to use these different programs.

I intend to bookmark the program you provided...that could be # 1.
