    There's also using the filter "dust and scratches" but you have to careful you don't go overboard with it.

    Dr Harvey Cushing

    the moire, fedezz, is the problem

    so far ive used a new layer and a gaussian blur and or median to dull the moire's in the scans and then created a new adjustment layer for brightness and contrast to further drop out subtle noise. dust and scratches and despeckle never really got the job done.

    the person requesting the scan didnt mind this look, i think it might be a bit dramatic

    you need to make an edge mask... retouch pro is a great resource... an edge mask is basically using the find edges filter, play with levels a bit to get the amount you want and use that as a mask to retain the details. then you use gaussian blur or dust and scratches to smooth the grain/moire.

    Heat, did you do the scan yourself?
    Try scanning at am angle as well, it may help remove the moire.

    If you scanned the image yourself, you might try using the descreen feature of you scanning software. Vuescan is an excellent program for this matter (and I think it used to be free). That's the best option. If you can't scan it again, try masking the background and play with the median filter. The figure is not that bad, I think that once you correct the values and add a small median, you won't even notice moire there. Right now, the most troublesome part is the backg. You can sharpen the whole image once you're done tweaking, and add a little grain to unify figure and background.
    Hope it helps.
