Local contrast enhancement problem

Are there any new plugins for Local contrast enhancement that are not prone to those ugly halos around edges in certain situations?
I used Topaz, Nik, Unsharp mask with high radius. I thought maybe there are some new arrivals that I'm not aware of.

Re: Local contrast enhancement problem

I assume you're aware that local contrast enhancement IS halos around things?

Not sure if this fits the bill but is supposed to offer not only global but local corrections - have a look and download the demo if appropriate

Google "Calvin Hollywood Freaky Detail" for a technique that uses Photoshop only, no 3rd party plugins. There are several examples and modifications to the technique out there.

One caveat, it uses Surface Blur which only works "effectively" on 8 bit images. Surface Blur works on 16 bit images, but takes so long to process it's impractical.

Another caveat, inspect the results carefully at 100%. Sometimes it creates nasty artifacts around small detailed areas with high contrast in the original. Need to mask them out.

This website has a free action for the Freaky Detail thing.

Re: Local contrast enhancement problem

Thank you for your replies!
I tried all of the sliders, and I know that most of these plugins do a pretty good job. But, whenever there are objects with large simple and smooth surfaces on, also, smooth backgrounds (I do a lot of plain colored boxes, books and similar product photography) there is that very obvious halo. I know that the best results are achieved with objects of fine texture and detail, so I end up D/B manually to achieve that sharper 3D look.

Re: Local contrast enhancement problem

Have you tried pushing the USM Radius close to maximum with amount very low and repeated passes.
