Re: filmscanners: What causes this and is there any easy solution ?

I'll try this and see how it compares with gaussian blur. I was hoping
someone would have a solution that didn't involve carefully selecting
sections of a 20Mpixel image. It takes ages to get it right and I wish I had
a bigger monitor there just isn't enough room for the picture on my 17 inch
screen.Sadly there isn't enough room in the house for a significantly bigger

Maybe, with practice I will be able to select sections better. Has anyone
tried adjusting their mouse movement settings (slow it down,reduce
accelleration) to make this easier ?
