Film Correction — Exposure Adjustment

Film is scanned by collecting the light that is passed through it. This makes it possible to adjust the brightness of the image by changing the amount of light (exposure) used to scan it. This is adjusted by changing the scan speed. With the Auto setting in Plug-in module FS, exposure adjustment is automatic. This setting should be used for most scanning jobs. If, however, you cannot achieve the effect you want with the Auto setting, you can manually overexpose or underexpose the image to create a special effect. Overexposing the image produces a lighter image. The scanning speed will be accelerated for negative film and slowed down for positive film. Underexposing the film produces a darker image. The scanning speed will be slowed for negative and film and accelerated for positive film.

Medium exposure		Overexposure

Underexposure

Hint

• If you are using the FS2710, positive film can be adjusted by three exposure stops and negative film by five stops.

•If you are using the 2700F, negative film can be adjusted by five stops. The exposure of positive films cannot be adjusted.
