RE: How to remove noise/sharpen further
Is it an extract/crop, a scaled down version, or the actual size?

Sorry I'm somewhat unsure about posting full resolution images on such an open forum. Here's a link to a larger version.

Post a significant extract at full size. Nobody can really make any use of it, and we can see the real picture quality. You can even make a composite with a little bit of everything so that we can make sure that something we do can apply to the full image:

Good idea, I've attached the full size crops below.

RE: How to remove noise/sharpen further
Did you take this picture with the max mega-pixel setting? (highest MP?) 2mp, 5mp 12mp, etc.

I always start with unsharp mask (Filters > Enhance > Unsharp mask)
Then / or you can try the find edges tool:

Also, weird enough someone has made a tutorial using a special high frequency layer (grain extract) technique which includes the blur filter, but the result is like unsharp with less haloing if any.

Good luck in whatever you decide to do!

RE: How to remove noise/sharpen further
Thanks a lot for all your replies. I think I'll look into applying a blurred layer on top of a desaturated duplicate... I think I'll look at getting a camera with a full size image sensor too.

Thanks again

RE: How to remove noise/sharpen further
I use a method similar to iForStyle007's second link that's a little simpler and has worked well for me:

Dupe the image
Gaussian Blur (20 to 50, experiment) then set the mode to Grain Extract
Right click on that then New From Visible
Hide the middle layer then set mode to Grain Merge
I'll move the opacity slider down to about 40% if there's any haloing.

Works pretty well for me, you might have to experiment with the Blur setting. I generally do this as the last step for pretty much every photo. I don't know if desaturating the Grain Extract layer really makes any difference.

It also works on just selections or with masks.
