It's really easy. You just use the "rubber stamp" tool. (I have a mac, so I hope it isn't too different on a PC) You click on the rubber stamp icon on the left hand side of the screen. Then choose the size of a circle that you need from the menu on the right hand side to cover the dust spot in question (make SURE that your image is zoomed out to 100%) Go to the image and push the option key along with your mouse clicker over an area of the image that you want to match the color over your dust spot. Now just go to the dust spot, press the mouse clicker, and PRESTO! Your dust is gone, replaced by the color that you previously sampled.

To remove other spots, just mouse click over the other dust spots. The sample that you are covering with is the same distance away from the new spots as the first sample was to the first dust spot. OK, this sounds confusing but it will be clear when you try it.

Good luck!

The clone tool works fine for a few spots and you do have to be careful no to over do it so you don't get that "clone" look. If you have many spots and scratches that go across the film as scans usually do then here's a technique that work very well and is much faster than trying to clone them out.

Dust and Scratch Removal Using photoshop 6:

Before starting you should know that you may have to do this process at least twice once for minor spots and once for tougher spots and scratches. Remember to work on a copy of the original file.
So focus first on the minor dust and scratches first. By the way, this technique is great for flyaway stray hair.

1. Open your file
2. Make your color, contrast, and density adjustments.
3. Create a snapshot of this current state by clicking the "Create a new snapshot" button at the bottom of the History palette. This will create a duplicate of your current image (state) in the history palette.
4. Magnify the image to about 100% or till dust spots are very pronounced.
5. From the filter menu select NOISE/Dust & Scratch filter. The mouse arrow will turn into a small box. Set Radius to 1 and the Threshold to 40 to start with. Find a dust or scratch mark on the original image (not the dust & scratch window) with the mouse cursor. Now that dust or scratch will appear in the Dust and Scratch window magnified. Now, slowly begin to slide the Radius slider to the left till the dust or scratch begins to fade but no further since it wont completely disappear. Now very slowly slide the Threshold slider to the left till you see the dust spot disappear. Make sure the not to slide the Threshold slider too far that the film grain softens. Now click OK.
6. Click the "Create a new snapshot" button again at the bottom of History Pallet.
7. Now you should have three STATES total at the top of the history palette. One: The original file as it was opened. Two: Snapshot 1 (original with Color, Density & Contrast Changes). Three: Snapshot 2 with the dust and scratch filter.
8. Select the history brush. Click on box to the left of Snapshot 3 (D&S filter) to set the history brush source. Now select the Snapshot 1 which should bring that color corrected original into view on your desktop.
9. Go to the history brush pallet and set the brush size to the size of the spots (not too large). Set Mode to Normal. Opacity 100%.
10. Start to remove your spots by painting over them now with the brush. Wala!

Repeat for more stubborn spots now. You don't want to do this for both at the same time since the brush may soften some spots more than you'd want.
