Epson Perfection V600 Photo Scanner

A ring-shaped pattern of stripes (called a Newton ring) sometimes appears on scanned images of transparent materials. This may occur if the film is curled.

To help prevent this from happening, place the film or slides with the base side facing up and preview using thumbnail preview. Then flip the previewed image by clicking the  mirroring icon in the Preview window. See Adjusting the Color and Other Image Settings.
