Quoting Monteycarlos (Reply 3): its a good technique to keep in mind though. In PS create a duplicate layer, go to adjustments and equalize and it will show up all the dust spots in the image. Correct as required.
Indeed, that works very fine. I have another way of spotting blemishes that might be helpful. That is by using the Levels graph (you can first use the duplicate layer function as Carl said). Press Ctrl+L and the graph will pop up. Then you can set a value between 100 and 130 on the first space of ´Input levels´ (or press Alt+I and type the numbers, that´s if you don´t want to use the mouse). The whole image will darken and will show the dirt clearly. Then when you have spotted the problem you can correct on the underneath layer.
Hope it helps.
