Stair Interpolation is not a digital camera specific action.  It is 
designed to enlarge a file without degrading the image quality.  It 
has the same goal as Genuine Fractals.  It is not a sharpener.  

Would some of the other people who have used SI have suggestions 
about dealing with huge size files that result from SI?  Lets say I 
scan a 35mm neg or transparency at 2400 on my Epson 2450 with a 
resulting 50meg or so file.  (With 120 film the issue isn't as 
extreme.)  I then use SI to enlarge to 10x15.  Now I have a huge 
file.  My instinct is to reduce the resolution prior to printing to 
480pi, save then sharpen and then work up the pre-print routine.  Is 
this the right workflow.
