+ "represent the part as true as possible to the actual camera used for editing. "
+ "The image should be taken from straight above the part, at as an orthogonal "
+ "angle as possible. It is recommended to take a lot of pictures this way and "
+ "select the best candidate.</p>"
+ "<p>The image should then be cropped with the knowledge of the image's LDU "
