AutoDetect Problems
AutoDetect works by being able to discriminate between different color RGB (Red
Green Blue) values and other image values. How well AutoDetect works depends on two
main factors.
1. Display. The more colors your monitor can display, the better PP8 is in finding the
right color. You want your display set to the highest value possible. This is usually 24 or 32
bit (true color). You can use 16 bit (64k) if this is the only setting you can use and still main-
tain an 800x600 screen resolution. Some display cards reset your screen resolution when
you increase the number of colors being used.
2. Quality of the image. The better the quality of the original image, the better the Au-
toDetect mode will work. We recommend using a digital camera with a flash. This seems to
provide the best picture quality and the highest contrast between colors.
What If AutoDetect Just Won't Work?
No problem. Simply redo the exam using the manual mode. PP8 effortlessly switches
between manual and auto. You can even perform a manual exam on one image and auto
on the second image.
