what is background noise? I see it mentioned but am not really sure exactly what it is, how it gets there, how to avoid it and how to get rid of it. With my last camera (film) I just sort of took nice animal pics, mostly on auto, and didn't really think about how they happened...just enjoyed being able to share them with friends. Then I went digi, discovered this site and NOW I want to learn!!
thanks

This is the site to NeatImage. You may have heard about it on the forums. The link has examples of what noise is and what the program can do to improve a picture.

thanks faifoi.....that is quite amazing. Is it legal to use NeatImage on a photo you're entering into a challenge?

| Often I find it as useful to use a litle gaussian blurr expecially on backgrounds where sharp focus is not the most important thing. |

Remember that the free NeatImage only can save with a very high compression setting. If you use it to submit to challenges, you may get comments about compression artifacts, and it may (probably will, depending on the photo) have a negative effect on score. If you use NeatImage regularly, you should buy it. We need to support those who develop good software. Besides, it's worth it's weight in gold sometimes.
Also, make sure you don't "overdo" Neatimage, you will get an overly smooth look to skin tones that looks very unnatural.

I try not to use freebies as much or the free trials cause you dont get all the features and the spyware is in them......I just heard so many things about it and couldnt wait to try...the photo I tried first is so blurry and I was hoping it could come out a little better.....Didnt realize that about skin tones but now that I look I can see ....Thanks for the tips...

you should also play with "median" (in PS - filter>noise>median) median tries to reduce noise while preserving edge quality. of course it can't preserve it completely, but its less of a "blur" tool and more of a "noise reduction" tool

There has been a suggestion to use gaussian blur to smooth noise out of backgrounds and I have done this successfully as well. This, of course, requires selective editing and would not be appropriate for any challenge where only basic editing to the whole picture is permitted. In addition, unfortunately, blur is not the same thing as the defocused occurrence of circles of confusion around details in the background and appears unnatural where in focus objects are blurred. I saw a picture in the rust challenge where someone had used motion blur (this is a big mistake) to simulate a defocused background. It looked like real big heavy objects were being flung around in the wind while light objects were just sitting absolutely still to have there foto taken. Does anyone know of any software which will create a realistic defocused appearance for cases where we had wished for a larger aperture to obscure the background and we can use selective editing?
Such software would have to make assumptions of the distance to details to be diffused, which might not be that hard as the closer ones will have sharper edges.
