Focus on the screen text looking just to the side of your finger, is your finger in focus?Now focus on your finger, is the screen text in focus?The bigger the relative distance, the more dramatic the effect.In bright light you have a small pupil, that increases depth of field, just the same as a cameras smaller aperture.Also, people think the eye is better than a camera. OK that is true as far as discerning different colours and shades as well as the eye has vastly better dynamic range in a scene.But the eye has poor vision away from the centre of view, look at a word on the screen and without moving your focal point, try to read text just 4 or 5 inches away.We think we see everything within our vision in focus, but the reality is, although our eyes are amazing, our brain fills in a lot of the world for us and we believe we see a lot more than we really do.We can't even see a photo properly, we recognise the shapes in a photo and use our photo memory of the known world that we have learned, to fill in the gaps.Our eyes dart across the image to better fill in those gaps that we pre-guessed.That's one of the reasons it's important to "lead the eye" in photography and to keep distracting clutter to a minimum.</blockquote>
