There's also a technique for using a very large radius and a small intensity, but I forget the details. A search of sharpening on dpreview would probably turn it up.

The local USM technique is often used to remove haze; you can read about it HERE (http://www.lonestardigital.com/photoshop_quicktips.htm).

Here's an example of my own: first, the original photo:

And after USM:

Ah, I thought I'd seen it here as well, but I couldn't remember.

Thanks Norm.

Sorry I have not replied before this, but I did not have access to the internet until now.
Thanks everyone for your help, I will try your suggestions out.
The usm I was thinking about was the one Jamison told cdi about (I'm not sure)
Again thank you all for your help:)

Are you guys mostly shooting jpg? just curious ... i assume it's a mix ... the reason I ask is that if you're using CS2 you can set your adjustments in Bridge to "auto-pop" when the thumbnails are being created. It's an amazing automation tool to jam through a lot of images very quickly with more than decent results. Check out David Jay's demo on it to get a sense of what I'm talking about ...

He told me ~20/60/0. I play around with those settings but usually just the amount. 10/60/0 or 30/60/0 for example.

Thanks cdi, I will try it out as soon as I have some time on my hands.
I have two teenage boys and a nine year old one to look after.:)

Thanks everyone here for discussion.
I personally find USM~20/60/0 very very very useful. FZ20 makes images mostly with weird hazy orange cast over them and this ~20/60/0 fix that.
At the same time I find that while ~100/2/0 does sharpen the image it also adds unacceptable amount of noise to an already noisy image from Panny cam.

I have a lot of firework pictures that are 'hazed' due to the smoke in the sky. I'm wondering what program you use to remove the haze.

Can't remember where I read the article but whoever the writer was used the term "pop" with USM 30-60-10. I looked through my bookmarks for the link to that article but couldn't find it....so, sorry can't give source info.

This thread is very useful. Never thought I could go from this 12x zoom, straight out of the camera mess:

to this:

with unsharp mask at full radius and low amount. So thank you to everyone who posted here. :)

If you want to sharpen it up with 50~150/1/0 or something like that, and then you find the noise gets too crap, try the folloing. Image/Mode/Lab Color.
Select the Lightness layer. Apply the USM as desired. Then change back to RGB. Et voila, much less colour noise as you would have gotten in RGB, yet the wanted sharpening.

I used Photoshop CS2, but I suppose any program that has the unsharp mask function can do it.

Coldrain. What do you mean by Lightness layer?

I think he meant lightness "channel." When you convert to LAB mode (image/mode/lab) RGB changes to L,A and B. L is the Lightness channel (look in the channel pallet.) When you make changes to the L channel, only the light value of the pixels are affected, not the color. When you are done, you convert back to RGB for printing.

I think that's it. Thanks Robert and Coldrain.
