E - Edge Sharpen
An edge sharpen filter cleans up the edges of an image, making it look cleaner and sharper. While edge sharpening does
make the image look cleaner, it also removes some fine detail from the original image. The strength of the edge sharpen
filter can be entered from 1 to 24. Entering a 23E gives the sharpest edges, but also increases noise in the image.
0E Don’t sharpen image (default)
14E Apply edge sharpen for typical image
ne Apply edge sharpen using strength n (n = 1-24)
F - File Format
