Maps after being scanned, would be opened in Photoshop. There the map
would first be blown up to its 100% size so as to be able to see
whether the map needed modifying in any way. Using the Rectangular
Marquee Tool, I selected the top left hand corner of the drawn map and
scrolled across to the top right hand side of the map. The scanning
process was often done very sloppily and the map page would come out on
an angle. Using the doted line created by the Rectangular Marquee Tool
as a perfect horizontal line, I could then go up to Image in the task
bar, down to Rotate Canvas, across to Arbitrary, and then select the
amount I wanted to rotate the canvas. The process could be repeated
until the top of the map was at a horizontal.
