True, a painter can capture a scene in a range of ways, from dead-on reproduction to work that is unrecognizable but for the emotion it evokes. While the end result will still have more distortion than an image shot with a rectilinear lens, it will showcase the ultra-wide angle of view that gives the fisheye lens a guaranteed place in the gear bags of many photographers. Most photo editors include some type of straightening filter, which identifies distorted straight lines and flattens them. While considering your final presentation, it's worth it to note that the digital editing that can turn a rectilinear lens into a fisheye-esque shot can work in the other direction as well.

Either way, your artistic sensibility and vision will be the guide for how to best present the final images.

You may decide to crop your image to a rectangle or square, or could keep it spherical to preserve the full effect of the heavy distortion around its rim.
Remember, you're seeing the rays of light that were funneled into the lens rather than those captured straight-on by a rectilinear lens. Once you have the photo, you'll have to consider another signature characteristic of the fisheye lens: Even though your camera uses a rectangular sensor or piece of film, the image will come out as a circle. Again, experimentation will help you determine how to adjust exposure to compensate for this issue you may even find that it adds a dramatic element to the image you're trying to capture. It's harder to keep the strong light from causing flares in the lens, as happens when you aim a rectilinear lens at the sun. Shooting fisheye images on a sunny day, or near a strong light source, presents another unique challenge. Hobbyists and professionals alike began to explore artistic ways to make use of this lens' signature distortion. This lens measured 8mm (the focal length) with an F/8 (the maximum aperture, or how wide the shutter can open to allow light through to the camera's film or sensor), and it brought fisheye photography to the consumer market. Other manufacturers followed suit over the next several decades, producing lenses with wider angles of view and greater clarity, with Nikon releasing the first interchangeable fisheye lens for 35mm cameras in 1962. Scientists could then use geometric principles to account for the distortion, allowing them to measure the distances between and sizes of objects captured in the image. As the name implied, the lens was intended to capture wide swaths of the sky in one shot. Lens maker Beck of London produced the first fisheye lens, labeled a "whole-sky lens," in 1924 for meteorologists and astronomers. The fisheye's signature distortion comes from this funnel-shaped path: Light at the edges of the frame has to bend further to reach the film or sensor, resulting in greater distortion.

Whereas a rectilinear lens is designed to behave like a window as light moves as straight as possible through its series of elements, the fisheye lens uses its elements like a funnel, bending a wide angle of light captured by the extremely curved outer element of the lens toward the film or sensor inside the camera.

In the digital age, these lenses allow one security camera to monitor a wide swath of property without moving, and automakers employ them as tiny backup cameras to help drivers stay safer on the road. Some of the earliest fisheyes, for example, were built by astronomers to capture images of the starry night sky. This offers fun artistic avenues to explore, but it's also very useful. The farther they are from center, the greater the curved distortion. The tradeoff is distinct: Straight lines anywhere but dead center in the fisheye image appear to curve. īut while wide-angle rectilinear lenses can capture angles of view approaching 100 degrees, fisheye lenses can stretch that to 180 degrees - impossible to do without the light-bending science they employ. The edge of the image is stretched far to the left, right, top or bottom of the center of the captured scene. Short focal lengths allow wide-angle lenses to capture a wide angle of view. Wide-angle lenses have short focal lengths, which is the distance, when a lens is focused on the farthest point possible, between the optical center of the lens surface - that is, the point in the lens, often at its center, where there is no distortion of light passing through it - and the film or sensor that receives the image. This renders straight lines as they appear in real life, wherever they are in the scene. Most of these lenses have a rectilinear design: Light entering the lens travels in a nearly straight path to the film or sensor (though all lenses are slightly curved).
