While in general every new image setting must be captured in the image by rescanning, the preview concept makes it possible to fully carry out a wide variety of image settings one after another and even to use 100% zoom to inspect the results. Only then all the desired image settings are carried out completely with a single scan that looks exactly like the image displayed earlier.
Different Types of Preview
Normal Preview: SilverFast shows the entire preview scan in the overview window. Tool settings and effects are shown by approximation. By clicking the magnifying glass icon single scan frames are enlarged to fill the preview window.
1:1 Preview: For an exact estimation of the effect of a tool, such as iSRD, an especially high-resolution preview scan is made. In the Navigator dialog, a yellow frame indicates the small image detail, for which all active tools are calculated and shown in the preview. Moving this yellow frame around always requires a recalculation of all tool effects on the preview.
HQ Preview: A high-resolution preview scan is performed for the entire image and all tool settings and image optimization effects will be calculated for the complete image. The detail of this end result proof can be moved using the yellow frame in the Navigator window. Thus, individual tool effects can be quickly reviewed in different areas of the image.
