Hello,

     Here is the anti-noise, anti-green pixel technique:

     Overview:   We will get PS to select the little bastards and then 
neutralize them
with our ray gun!

1.   Blow up your image so that you can see the pixels easily.
2.  Eyedropper tool> point sample
3.  Select>color range> sampled colors
4.  Fuzziness= 50
5.  Clear the image box that shows your selection progress by clicking on the 
first
eyedropper and selecting a red or magenta pixel.
6. Now click on a green pixel.. Switch to the eyedropper that has a " + " 
next to it...
you will be accumilating your selections from now on.
7.  Choose a variety of the green weenies making sure you are going after 
green pixels only!
Press the space bar to move around the image to choose them.
8.  After about 10-20 selections press OK.
9.   If you have something that is really green in the picture like the 
Dumbell Nebula,
zoom back to full page (command/control 0) and using the lassoo tool with the 
option
key depressed, subtract any selection from the green areas you want to keep.
10.  Go back to pixel magnification- hit command/control M for curves- go to 
the green
curve and drag that puppy down until all the selected green pixels become 
neutralized
with your anti-green ray gun. By subtracting green, you are in effect adding 
magenta,
don't go too far, just neutralize the green to the surrounding pixel colors.
10.  Go back to full screen, hit command/control Z to toggle back and forth 
between
the zapped version and the unzapped. Is it enough? Need more or less? Just go 
back
to curves until you get what you want.
11.   Hit command/control D to deselct everything. All done. Green pixels got 
smoked...

Footnotes:   Some times you might have to do this twice if you did not select 
enough green
pixels the first time. You can also adjust the density of the selected pixels 
by switching
from the green curve to the RGB curve. Some times you have to adjust the 
fuzziness
up or down to get the right amount of "color choice" in the eyedropper tool.

    I hope I have not omitted anything...

     Have a good one,

      Tony
