help remove grain from a scan

HI
I scanned in these race cars from an ad. What is the best way to remove the dot do to the printing process?
I tried several things, like blurring the different channels, but I didn't get good results.
Thank you.

Hi

could you please supply these photos with bigger file size, as that low of resolution isn't much to work with.
close to the max for the website would be just great.

thanks

FFT Filter

In RetouchPro's tutorials there is an excellent help aid. It was done by one of our members and he describes how to use the FFT Filter.

I used the FFT filter first. (it helps remove artifacts from paper scans)
Neat Image second. (it helps remove noise)
Adjusted the levels just a bit. (gave it a bit more spark)

Placed it here.
#1 - original
#2 - using the fft

I ran Surface Blur on each channel, then a Smart Sharpen on the entire image.

Slipchuck - I'm not sure how to proved a larger file.
Candice - That looks really good, and I like the spark. What is the FFT filter?
Swampy - Thank you - I tried to blur just one channel, but it didn't do much, yours looks good
AL - Thanks for the link, I have had that happen with our digital camera in low light. I like yours it is still a little grainy but the edges are sharp.

Thanks for the help

Cathy

You can look up the FFT Filter and the tutorial under the Search key on this site. It will explain things very well.

Ok, I left it a little bit grainy since it's much better looking in this way. The criteria for me is the picture should look good inspite of some "technical" drawbacks. I think, some noise is acceptable if it makes good to a photo.
