I have learnt something about scanning
Well,
I was unhappy with last nights scanning. Last night I was using my semi professional scanner and scanning through Adobe Photoshop which would then open Silverfast (Professional) scanning software to carry out the scanning. The scanning was brilliant. When the scan then transferred to photoshop the image quality was reduced. Tonight I have scanned in Silverfast directly (still using the same scanner) and then opened the photo in Aperture to edit it. A lot better quality.
I have scanned at the same 600 dpi as I did last night.
