Thanks for the tip Erick... I'll try that with the next roll (my first roll of proper film in my mind... as I didn't know that first one was in there when I got the camera).
I did however have some luck with converting the negative... my printer can only do 1200dpi... but it gave quite acceptable results (quite interesting to see my finger prints blown up to screen size).
I also found a handy website with a small downloadable algorithm that takes most of the work out of the inverting/colour correcting for you.

The results of my conversion should be below... bare in mind that my original snap would have been of very poor quality as at the time I did not use a tripod and I currently don't have a shutter release cable (about to check eBay for one)... but at least it is a "proof of concept" for the "normal" scanner negative film processing.
