What Rubbish?!

Do not make a definite judgement of something, and rubbish it, just because you don't have a clear view and understanding of it. This photo of an OHP slide may be blurred, but that doesn't mean that the literature contents on the slide are nonsense; it's only one bad picture after all, maybe be due to a bad coincidence of camera shake and shutter-opening. Either move closer for another take, or steady the hands and auto-focus again, not condemn everything once and for all. If all the photos turn out bad, then it might be due to your camera's inadequacies or more-likely, the camera user's own technical inadequacies and insensitivity... At the end of the day, if everything still turns out blurred and twisted, then it'll be something to feel very sad about~
