Digital photos- reducing noisy blacks. - Photography

Does anyone have any suggestions on reducing noise in digital-origination images, particularly in the blacks. My Canon s45 gets quite noisy at 400asa. I read about a technique somewhere, where you shoot the photo then shoot another frame 'black' (a noise pass) and then marry the two in post. Can anyone elaborate on this technique? Is there an easier way to do a general clean-up thru photoshop7? n.t....

    youre probably losing too much detail at 400asa on the s45. i used to find
    even 200asa was irritating on the s45.

    I only use 50 or 100 on my S50.

    I find that 200 or 400 are too noisy.

    Either Neat Image, which is free for private use, or Applied Science
    Fictions Digital Gem, a fully commercial product, would be my
    recommendations... Gem is a easier tool to use, Neat Image has more
    options, but it's easy to get a plastic finish with Neat Image if
    you're not careful...

    Generally though, as someone who sells Canon equipment, my advice
    would be to keep it under 200 ISO...

    Now you have me worried.... I can't remember what I set the S50 at before my
    wife left for the US with it. :-(
