Extremely heavy noise

Hi Everyone!

Wondering if anyone has any suggestions to get this any better/sharper?

I use a Mac and Neat Image doesn't work on Macs.

Sharpening with the hi-pass filter brings back the noise, as does the USM... Define selective makes it even more blurry..

I'll post the orig first and then my last effort

Thanks for any tips,
Diane

It looks good but the whites are kind of blown out. Maybe you can get rid of the noise yet keep the detail in the cake. Diane, you may also want to try downloading a noise reducing action from http://www.canonians.com/noise.htm. It works pretty good.

Cheers
Duv

Hi Diane,

Not bad! ... but I agree with Duv about the whites....

I find the task of reducing noise quite delicate because, inevitably, you lose details...To regain some of the details back, you tend to increase the contrast which can lead to blown out whites and much too dark shadows...

Trying to prevent that, I tend to work a lot with Luminosity and Shadow Masks (Diane, you are an expert on those by now!!! ) which allow me to blur and/or sharpen exactly where I want to ....
  • I used them with this picture as well (after cleaning it up a bit : Clone and Blur Tools and Healing brush to blend in the corrections) .....
  • I used the Levels on the Channels and the Selective Colors Tool to correct the colours.
  • I used the Custom Filter to sharpen the image.

With all the compression, etc. the original I posted above doesn't really show the extent of the damage in this pic so I thought I'd re-post it for the benefit of everyone taking a look...

Duv, that noise reduction tool doesn't work on a Mac

But thanks anyway!
Diane

Flora,

Once again you've done a very beautiful job and are a great inspiration!!

I tried it again from the beginning, adjusting the levels in channels and also replacing the green channel... It is looking much better, but I am still wondering how you got rid of all the noise. I found the luminosity mask helpful in getting the contrast and colors right (setting the blending mode to hard light) but not to get rid of the noise.

In the best version I posted above, I used the dust and scratches filter and then a layer mask which ended up with it losing detail and getting a bit blurry as you mentioned above. Then when I sharpened with the high pass filter, the damage kept coming back!

Do you always recommend adjusting the levels in channels rather than using auto contrast, auto color or the general levels adjustments??

What steps would you recommend to finish up from the post below?

With much appreciation,
Diane

Hi Diane

I'm quite surprised about the noise reduction action. An action is just a series of PS steps and should work on any platform. Can you give me any details as to why it wouldn't work? Were you able to download it to your actions palette? If so, what happened when you tried to run it?

Cheers
Duv

Hi Duv,

I just wasn't able to download it.

Do you know what the steps are for it??

Take care,
Diane
