Can anyone give me a bit of a tip on how to remove noise from a scanned photo? Just the regular RGB noise. I'll get to posting an example. |

You could try switching to LAB mode, use Gaussian Blur on the A and B channels and then run Despeckle and/or Dust and scratchs on the L channel. This works well for many noise types expecially Jpeg artifacts. But I takes some expermenting with various setting. |

I seem to recall there being a trick where if you scan your image in at 15° and then straighten it out again in PS, that will reduce some noise. I can't personally say if this works or not since I haven't tried it. |

Well the 15 degree trick is mainly for scanning halftone screened origianls. Halftone screens are typically angled 15 degrees from one another, Yellow sometimes placed at a 13 degree offset. By scanning at 15 degrees, you can help prevent morie paterns from accuring. But it doen't realy help with eliminating the halftone pattern. |

OR - I could just chuck my $75 scanner and get a decent one. |
