I have said in the past that moving up from A4 sized images to A2 would present a few challenges; well it has. principally has been the digital scanning. having an excellent A4 scanner, scanning is normally straight-forward, that is in simple terms. Oh dear: computers are not that simple!
The above A2 water colour, enhanced with a little ink work comes to mind. Four scans across the bottom, which were digitally joined. Then four scans across the top which were also digitally joined. Then those two images were digitally joined manually. The computer did not like me taking control. It took me a couple of hours; good grief!! The result doesn't look bad either.
I plan to produce several watercolor images of this size in my present project, Oh Dear! Maybe I will find a simpler way around this scanning malarky.
The picture is of the coble landing at Filey, which is called "A jolly good read". Note the book worm on the extreme right.
