need help reducing digital noise from crappy...

compact camera...

is that possible?

I have a few photos that a magazine wants to print, however they were made with a crappy compact digital camera and worked on afterwards... but the digital noise on the shadow areas are awful!

wonder if there is a way to make this looks better without losing sharpness!

I have attached a print screen and a slightly larger file can be found here if anyone fancy a go at it:

Re: need help reducing digital noise from crappy..

I once heard someone talking about a plugin called Noise Ninja or something. They somehow figured out the noise patterns for different camera models and use some crazy math to reduce the noise. I've never used it, so I don't know how well it works or if it would have support for point and shoot cameras, but it may be worth looking into.

yes noise ninja will do it. You have control over which colours it works on.
Or you could try putting your pictures into lab mode in photoshop. Open the two colour channels A and B and use a light blur on them.then combine with the lightness channel again (L) and it should have helped get rid of some of that colour noise.

lab idea is great to tackle the color aberrations.

Re: need help reducing digital noise from crappy..

Topaz Denoise does an excellent job but getting the best results takes some effort. Lightroom3 / ACR noise reduction does good job as does Noise Ninja, Nk Dfine, Neat Image and 3-4 other plugins.

This was taken at ISO 3200 with a crop-body (D300s) and processed with the LR3/ACR 6 Noise reduction. Looks pretty good for such a high ISO.

Yes, there are several third-party plugin solutions for removing noise in digital images.

Re: need help reducing digital noise from crappy..

By the way guys, make sure you are working in 16-bit mode when converting to and from LAB or you might introduce a bunch of unwanted dithering to your image (making your noise reduction harder). Also, you pretty much never actually need to convert to LAB if you make use of the Hue/Saturation/Color/Luminosity blend modes in RGB...

There is no way of simply removing all the noise; so just reduce it as best you can without making it look strange. Depending on what size the magazine will use the images at, the noise might not turn out that harsh (zoom to 50% to get a rough idea).

Other things that might benefit the image in addition to the noise reduction:
  • Increase Vibrance and Saturation
  • Selective sharpening (use an edge mask)

Here's my attempt using only native Photoshop tools (no plug-ins).
I went quite heavy-handed but tried to not overdo it. I noticed the Smart Blur filter could help a bit with the more noisy surfaces.
