Few people may realise but the digital revolution with both video and still cameras has brought one very negative aspect to capturing your favourite moments. The use of the LCD screen as the main tool for composing and focusing on the subject means people take photos with their hands stretched out. This photograph of an Asian man perfectly demonstrates the issue.
Now, let me explain what is wrong with it. If you put the camera to your eye and use the optical viewfinder or even the in-build electronic viewfinder your camera is relatively steady as it rests against you. If you move a little bit it probably won’t even matter and the photograph will be sharp. When you stretch your hand out and move by the same factor the length of the arm multiplies that movement resulting in blurry images.
