I f you want to get into scanning your own film, Mark Segal has the right suggestions.
There is a learning curve to learning to scan well - beyond making sure the film is flat and in focus ( I like the wet scan tray in the V750 package with AZTEK fluid) the basics are: scan at 16 bits per channel, use ProPhoto RGB especially for landscape work, leave the black point at zero and move the white clipping point in to about 5 points beyond the end of the mountain range in the histogram to ensures you use the full dynamic range of the image and don't dynamic range on information that isn't there. The resulting file will be quite large but really you only want to scan film once so you might as well do it right.
You also want a relatively low contrast scan. It is tempting to make it just as rich and contrasty in feel as you think you'll want the final output to be but that is what Photoshop is for.
