Normal: used when the original contains both text/CAD lines and pictures/graphics. Photo: this method exists for historical reasons and was designed for pictures; however, better results are obtained with Graytone and there is no predefined type of original that uses this method. Adaptive: used for CAD or text documents where the background is barely distinguishable from the lines or characters, where, for example, the original is a blueprint or an old and worn out document. This method is similar to Normal but extracts the background gray level from the input image. 3.5.2 Lightness This setting increases or decreases the lightness of the image. It can be used to compensate for dull or faded originals. Possible values range from -3 to +6 3.5.3 Sharpen This setting is used to sharpen the image; it enhances the edges between areas of different colors (see the explanation in section 3.4.7). Valid values are On or Off. 3.5.4 Blur This setting is used to smooth the image. It is useful when the scanned original is "noisy" (see the explanation in section 3.4.8). Valid values range from 0 to 12. All comments made in section 3.4.8 regarding the combined usage of sharpening and blurring apply here as well.
