Noise/Grain Reduction Software (Q's & update)

Thanks for the help in prior thread...


Tried Noise Ninja on a couple of Baby Buzz's sports photos, and it does get rid of a significant amount of noise and graininess, but seems to do so at the expense of sharpness... could not get close to the original sharpness after filtering, but there wasn't a S3 IS filter package available, only for the S1 & S2, neither of which has noise/grain problems to even experiment with. any clues on how to tweak/create a filter that doesn't decimate the clarity?

I tried re-sharpening after ninja-ing, and am left w/ a nice soft-focus picture. I sense you guys are on to something here w/ this type of software, I'd just like to figure out how to make it work right. Baby Buzz's first game is at 8AM tomorrow, so I may have to play it safe and forego sports mode again. Thanks,


Sometimes it is what it is...
and then there's times when it's really better.

FWIW a lot of noise & grain, although nasty-looking on screen, never will be apparent to the naked eye once printed or viewed on-screen at normal magnification.

A few more free demos worth playing with.

NeatImage: []

GrainSurgery: []

Dfine: []

Noise Reduction Pro: []

They all will have canned profiles as a starting point, but for best results you will need to tweak the settings per your liking. Less noise-reduction is better.

You might want to scour the individual software sites to see if any of these packages has a current profile for your camera.

I find that once you use these regularly, you don't really need the profiles, jst a quick pass with one of your previous settings.

Even Photoshop has a noise-reducing filter, and many other ways to accomplish it.

You could do your noise reduction on a layer, and then selectively mask areas that do NOT need noise reduction.

Also keep in mind that if you have a whole lot of won't be able to get rid of it all and keep the detail and sharpness...If you do gert rid of it all, you will end up with a soft image. So just print small and everything will be ok.
