    Re: Removing Grainyness

    The grain look you are referring to is called "noise". There are plug-ins that do this such as Neat Image, Noiseware, Noise Ninja and Photoshop CS2 has a noise removal filter as well.

    Neat Image has a free version for non-commerical use. Download Page

    Noiseware also has a free version for non-commerical use. Download Page

    CS2 Noise Removal Tut

    You can also try removing the noise by switching to LAB mode and bluring the A and B channels. Here is a tut.

    Hope this helps!

      I know I saw a noise reduction tutorial on the net months ago using some actionsin LAB mode...but I don't remeber where...the greyness is colour noise due toi high value of ISO,,,The tutorial made a nice result, not 100%, but nice...

        The "grain" is actually severe color noise. One run through with the noise filter Noiseware smooth it out but as you can see from attachment 1, there is a lot of residual yellow. I took the image into LAB and reduced the yellow resulting in at6tachment 2.

          Hi there

          As Paul says a good noise reduction program can help some.

          I ran this example thru imagenomic software

            I first copied the layer using screen blending mode and then used Neat Image.

            Still with residual grain but I suspect more aggressive blurring would dull the image somewhat.

              Removing noise and stuff
              by Aurora Graphix
              This should be an easy image to fix as there is very little damage. But oh, the noise! Stop the noise! lol

              What would be the proper workflow to fix this up for printing?

              Thanks for any guidance in advance

              Removing Noise? Use a Surface Mask
              by gmitchel
              The "Tip of the Week" on my site demonstrates how to use a surface mask when removing noise. Keeping noise removal away from edges prevents it from softening your images.

              Best for Removing Grain
              by crazyfly1
              Hi, was wondering, I have some photos shot with a 5D in awful light. These are wedding shots. The 5D went all crazy and shot at ISO 2500. What's the best software to remove the grain? I tried neat image and it does OK, really clunky though, I can't believe they haven't updated the interface in at least...

              Removing dust,lint, and scratches from a photo
              by Gerald McClaren
              I would like to know which is better in removing dust, lint, and scratches from a photo between median or dust and scratches removal in photoshop Cs2. The reason I'm asking is because I had used median to remove some dust, lint, and scratches from a photo and they all came off great, but the texture...
