For digital cameras using smaller imagers such as 1вЃ„ 4' and 1вЃ„ 3' format CCD or CMOS sensors, the focal length of 'miniature' fisheye lenses can be as short as 1-2В mm.ДЇisheye lenses also have other applications, such as re-projecting images originally filmed through a fisheye lens, or created via computer-generated graphics, onto hemispherical screens. For the popular 35 mm film format, typical focal lengths of fisheye lenses are 8-10В mm for circular images, and 12вЂ“18В mm for diagonal images filling the entire frame. Mass-produced fisheye lenses for photography first appeared in the early 1960s and are generally used for their unique, distorted appearance. Their focal lengths depend on the film format they are designed for. The angle of view of a fisheye lens is usually between 100 and 180 degrees, although lenses covering up to 280 degrees exist (see below). :вЂЉ145 Their first practical use was in the 1920s for use in meteorology to study cloud formation giving them the name 'whole-sky lenses'. Wood based on how a fish would see an ultrawide hemispherical view from beneath the water (a phenomenon known as Snell's window). The term fisheye was coined in 1906 by American physicist and inventor Robert W. Chromatic aberration can clearly be seen toward the outer edges. With symmetrical architecture like this, a lot of times there will be a clear marker on the ground to signify the exact middle of the room.Circular fisheye photograph of Oude Kerk Amsterdam. This was taken at the Gaylor Texan in Grapevine, Texas and this ceiling is absolutely massive. ThereвЂ™s no way you could capture this much of a ceiling with a normal lens. Doing this will allow you to capture a nearly 180 degree view of a scene while avoiding the distorted, crazy look of a fisheye lens. Just make sure your horizon is towards the middle of the frame.

If you have a landscape without straight lines (buildings, trees, telephone poles, etc) you can sometimes position the lens in a way that it simply looks like a wide angle lens. Sometimes, you donвЂ™t want distorted lines but still need that super wide angle. Sometimes, a fisheye can be used simply to capture everything you want in a scene. Shoot Super Wide Landscapes Without The Fisheye Look Just be careful, you might get home and find your legs in the bottom of the frame -).ДЈ. The exaggerate this distortion, place the horizon dangerously close to the top of the frame. If you place the horizon in the middle of the frame, it will be perfectly straight across the entire image. One thing to note when using a fisheye lens is this: The further you move an object or line to the edge of the frame, the more distorted it becomes. Not every image is going to come out, but you can almost always walk away with a few keepers. To do this, simply cradle the lens with your left hand while using your right hand to pivot the camera body around. Next, you need to spin the camera 90 degrees counter clockwise. To get this radial-blur effect, simply slow down your shutter speed to around 1/25th of a second.

When IвЂ™m shooting a reception, I get right in the middle of the dance floor and just shoot away. These receptions are usually in low light and are a challenge to get great images out of. Shooting a wedding reception with a fisheye lens can be an absolute blast.
