Solder Mask Layer

Designing my first board I checked my solder mask layer. It seems to be 'inverted' from what I expected. i.e. solder pads appear to have the mask applied over them, tracks and the copper pour areas don't. Is this correct?

Yes this is correct, the format is historical for what has been used in the industry.
As this is your first design make sure you check out all the information on-line.
