lonesky1 Posted June 29, 2008 Share Posted June 29, 2008 Hello, I'm making this enquiry as a beginner again. It concerns the use of the feature "Noise Reduction": can this be used to improve the clarity of a graphic that has a certain amount of "dithering" or "artefacts"? (ie. what appears to be "stray" pixels just adjacent to the actual image pixels). The 2 parameters in 'Noise Reduction': Radius & Strength: There are no explanations in "Help" on them. Can someone please explain what they mean and how to use them to reduce noise? Thanxx again. Quote Link to comment Share on other sites More sharing options...
xRyan Posted June 29, 2008 Share Posted June 29, 2008 they work like add noise, but in the opposite try adding noise to any picture and see what it does to the quality. thats what reduce noise can take away. Quote [ My Gallery ] Link to comment Share on other sites More sharing options...
lonesky1 Posted June 29, 2008 Author Share Posted June 29, 2008 I don't know how to add noise to a picture (or graphic), ryan. I have a small graphic that appears to have some 'noise'. I've tried the 2 functions to reduce or eliminate the "dirt", but it seemed to make no difference. Can someone, anyone, please care to explain those 2 functions, because they are not explained in the 'Help' section? Thank you Quote Link to comment Share on other sites More sharing options...
Aussi3ies Posted June 29, 2008 Share Posted June 29, 2008 You said you don't know how to add noise to a image/Graphic. Its very simply here's how to do it. Effects > Noise > Add Noise Play around with the settings until you get your desired result.

Curmudgeon Posted June 29, 2008 Share Posted June 29, 2008 If the "dirty" spots are easily accessible, I'd try to use clone stamp first. Quote Link to comment Share on other sites More sharing options...
lonesky1 Posted June 30, 2008 Author Share Posted June 30, 2008 If I used Clone Stamp, would not that also copy the "dirt" (or dithering artefacts) from the original image? Thanxx Quote Link to comment Share on other sites More sharing options...
Curmudgeon Posted June 30, 2008 Share Posted June 30, 2008 If the background is all the same color (no gradient or anything applied) the clone stamp would be a good choice. Just set the anchor point to an area that's "dirt-free" and draw that area over the dirty areas. Quote Link to comment Share on other sites More sharing options...
lonesky1 Posted June 30, 2008 Author Share Posted June 30, 2008 Curmud, I'm a total beginner here, & I'm not familiar with most of the tools (including Clone) here. I've read the very brief paragraph on 'Clone Stamp' in the "Help" section, but it doesn't explain how to go about it. I'm going to try to work it out "on the job". Can you give some steps for "Just set the anchor point to an area that's "dirt-free" and draw that area over the dirty areas"? Thanxx again Quote Link to comment Share on other sites More sharing options...
Curmudgeon Posted June 30, 2008 Share Posted June 30, 2008 I assume this is something like what you see...the residual bits around an object Select the clone stamp, and find an area that is "dirt-free". Click CTRL and left-click the mouse button to select the anchor point. (the pointer turns to an anchor while you hold CTRL) That will be the area you will be clone stamping from. Then left-click and draw over the "dirty" area and it will be drawing from the clean area over it. Quote Link to comment Share on other sites More sharing options...
