both SS and StockXpert rejections are for noise.

How do things like Noise Ninja work, what is the best/cheapest. I run Photoshop7.

Are they PS add-ins? and, do you leave it until you are ready to save the image?

You can download trial versions of Noise Ninja, Neat Image, Noiseware and try them for free. I personally prefer Neat Image Pro. It lets you select an area in your image (for example, blue sky where you normally have a lot of noise) and then it creates an automatic setting for that image. You can either select default, which is what I normally do, setting to remove noise or fine tune it more. The program works as Photoshop Plug In or as Stand Alone, so you should not worry so much about your Photoshop Version. You can also try Photoshop CS2 for free for one month if you go to Adobe´s site. There are lot´s of programs out there and the top three listed above all do a fine job. But it´s a matter of personal choice. Just download the three trial versions, play around with them, and see which one you like the most. I think that Noiseware is the easiest to use, but you don´t always get the best results. You should not worry about SS noise rejections so much. They are obsessed about it. I think if they see a photo with blue sky or some shadows they will almost automatically reject it for noise despite the ISO setting. SS´s working definition of noise is not a very good one.

Forgot to mention. for many other sites, SS standard image is too overfiltered or plastic. I would process my SS submissions seperate. Do not apply any sharpening after you run an image through noise reduction software. I do it as a last step, after levels and curves adjustments.

Tried to post this last night but the new look seemed to prevent me logging in until now.

My vote is for Neat image the free version is good and the paid versions are better, can queue images save filtered images as TIff or JPEG 12 and PS plug ins for the pro versions.

Over filtering can be a problem I usually just filter the sky one method I adapted from a lost source is listed on this page you have to scroll down.

I won't join the arguement whether to filter first or last just as long as you do it at some point.

A good idea to check your cameras settings my Canon 350D default setting is iso400 ouch iso100 is more sensible for normal daylight conditions.

when i was decided i did a few searches and found noise ninja to come out on top in a few tests.

I have used them since and am happy. If you buy the most expensive version you can use it as a plug in and in actions in photoshop. I usually use it on a seperate layer on my images and just use it on parts of the image like the sky.

ah yes, i think that is the one that i looked at.

my personal opinion, neat image + camera profile is the best choice considering quality of output and time of processing

Please! If you have any respect for your images, do not use noise reduction software. If you can get it right in the camera;as in my quote: (which someone else has stolen and called it their own) "Shoot like photoshop doesn't exist!"- Now that doesn't mean don't use photoshop,because we all must tweak our images at times,but if you use the lowest(where appropriate) ISO rating, and have adequate lighting, your noise will be minimal. The best way to eliminate noise without "plasticising" the image is to use the blur tool from the photoshop toolbox,dependent upon the degree of noise present,set this between 5 and 30%, use a soft brush and just brush over any offending areas. Another way to do this if you don't feel confident about using the blur tool is this:

Smart Noise reduction

1. Image>mode> lab color
2. Channels palette-select channel "a"
3. filter>noise>median> 5 pixels
4. Channels palette-select channel "b"
5. filter>noise>median 5 pixels
6. Channels palette-select "lightness" channel
7. filter>noise>Despeckle
8. Image>mode>RGB: DONE!
