# Smart Points does not Process the Image Correctly?

Try using extended points or manual detection instead of smart. Extended contact points uses more of the droplet profile. It is particularly useful with images with more than 120 degrees of contact angle. Manual contact forces the system to calculate the angle at the point the user wants to. If this doesn't work, there may be problems with the image quality. Retake the image with different lighting conditions.
