How Good is a Scan?

As a photo scanning service it’s hard to explain to people how good a scan is prior to them getting it. It’s also tough to find some measure potential clients are familiar with to express the quality, say, of a 35mm scan.
On Friday I came across the Panasonic stand at the Goodwood Festival of Speed where they were promoting their new Lumix range of top quality digital cameras. Looking in the detailed specification it gave the image dimensions in a measurement that meant something to me. Their top of the range camera delivers 4000 dpi.
They quote the camera as being 12.1 megapixels - so there it is, 1Scan photo scanning at 4000 dpi is equivalent to a 12.1 megapixel digital SLR.
