Dive In

About The power of contrast. I'm not 100% sold on this image, but it just makes the cut and I need some colour on my stream. It's an oldie, before Levi. Yes I know its a little 'hot' in the middle -that is why you need to 'Dive In' I remember when I shot this Matt and I were almost waist deep in water ;) Chose your branch to sit on... post a note ;) I'll go first. Enjoy. - Canon 50D - ISO 100, f9, 1/200, 10mm. - Sigma 10-20mm f4/5.6 lens. - Tripod. - 6x17 Crop in Lightroom 3.2. Processing - Contrast and Saturation in Digital Photo Professional 3.0. About Sunrise Sunrise is the instant at which the upper edge of the Sun appears above the horizon in the east. Sunrise should not be confused with dawn, which is the (variously defined) point at which the sky begins to lighten, some time before the sun itself appears, ending twilight. Because atmospheric refraction causes the sun to be seen while it is still below the horizon, both sunrise and sunset are, from one point of view, optical illusions. The sun also exhibits an optical illusion at sunrise similar to the moon illusion. The apparent westward revolution of Sun around the earth after rising out of the horizon is due to the Earth's eastward rotation, a counter-clockwise revolution when viewed from above the North Pole. This illusion is so convincing that most cultures had mythologies and religions built around the geocentric model. This same effect can be seen with near-polar satellites as well. Sunrise and sunset are calculated from the leading and trailing edges of the Sun, and not the center; this slightly increases the duration of "day" relative to "night". The sunrise equation, however, is based on the center of the sun.
