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.

blurring apply here as well.
