More control on the postprocessing is needed.
In Adobe Scan, after you capture an image, its values are automatically adjusted but sometimes you loose faint details. Adjustments of Brightness and Contrast are of not much help in this situation and the filters are mainly useless too so I have to sabe the image without any adjustment and then adjust curves in Photoshop.
It would be great to have a curves adjustment right into Adobe Scan as this would avoid having to use Photoshop (or any other image editing program) later just for this.
