I am using CS2, and I wanted to know the best way to upsize an image after finishing the brush scene I am creating, since it seems that brushes are limited to appx 2400p in size.
I am doing an image that is 4600 X 7000 in size, so I wonder if I can create my imagery on a 3500 X 2300 size, and increase it double without loosing resolution? Can I get some suggestions on the best way to insure a clean resizing? 

Thank you...
