Fisheye-Hemi Plug-In – See the entire Hemisphere without the distortion. The Fisheye-Hemi Plug-In automaticaly remaps your fisheye images to minimize distortion and maximize the preservation of all image details.

About Fisheye-Hemi™ Plug-Ins
Fisheye-Hemi is a set of plug-in filters for Photoshop, Photoshop plug-in compatible applications, Lightroom and Apple Aperture which provide correction for hemispheric fisheye lens distortion. Fisheye Hemispheric lenses in the hands of a photographer provide an expanded view of the world across approximately a 180 degree diagonal field. Until now, the primary option available to the photographer was to render these fisheye images using rectilinear mapping techniques. These methods have many drawbacks, such as distortion of people near the perimeter and loss of resolution and data. Although the image is similar to what is seen by the eye, printed, the images appear distorted.

Fisheye-Hemi offers an aesthetically pleasing and natural view of the image using a unique mapping technology! Fisheye-Hemi provides a more normal view of people by not distorting their faces and bodies, and straightens vertical lines. It has improved resolution of the image plus it displays the intended composition and framing better than other un-warping programs. The most important requirement for Fisheye-Hemi is to not distort people, no matter where they are in the image. The faces and bodies must appear as normal as possible; given it is a fisheye lens! The Fisheye-Hemi Plug-In preserves the people.

Another important feature of Fisheye-Hemi is the clarity of the mapping. A rectilinear mapping will discard approximately one third of the pixels and crop to the center along the horizontal axis. Photographers purchase a lens to capture up to 180 degrees. Much of the data is discarded in a rectilinear view. Fisheye-Hemi uses almost all of the pixel data in that view. A rectilinear view will shrink the center of the image which has the most detail. Fisheye-Hemi preserves this detail by using advanced mathematics to preserve all of the content of the original fisheye image.

Additionally, a rectilinear projection discards much of the framing of the image as composed by the photographer through fisheye lens. Fisheye-Hemi preserves all of this framing; what was seen on the top and bottom of the image in the viewfinder is included in the processed image. Last, but equally important, Fisheye-Hemi straightens vertical lines. The Fisheye-Hemi Plug-in produces an aesthetically pleasing image from the fisheye lens!

Fisheye-Hemi 1 (Circle)
Works best with a lens and camera combination that covers 180 degrees horizontally across the field, such as a Nikon D80 with an 8mm lens.

Fisheye-Hemi 2 (Full Frame)
Works best with a lens and camera combination that covers 180 degrees diagonally, but the captured image has no black edges in the corners. This combination is commonly called a “full frame fisheye image”.

Fisheye-Hemi 3 (Cropped)
Works best with a lens and camera combination that covers less than 180 degrees, where the captured image appears almost normal with mild fisheye distortion.

Fisheye-Hemi is a plug-in filter which provides correction for hemispheric fisheye lens distortion.
Fisheye Hemispheric lenses provide a broader view of the world than is possible with any other lens. Until now, the primary correction option available to the photographer was to render these images using rectilinear mapping techniques. These methods have many drawbacks, such as distortion of people and loss of resolution and data.

The Fisheye-Hemi filter provides an aesthetically pleasing and natural view of the image using a unique mapping technology. Fisheye-Hemi provides a more normal view of people when photographed at acceptable distances. It improves the resolution of the image by including more of the original pixels (in comparison to a rectilinear view), displays the intended composition and framing, and straightens vertical lines.

How does Fisheye-Hemi work?
Let’s begin with a basic understanding of what a fisheye lens does and how the eye perceives the information. Light projects conically into the human eye. The cornea and lens are similar to a fisheye lens. The light is projected onto the curved retina. The human brain uses complex mathematics to correctly interpret the objects that you see into a three dimensional image.

To a person holding a camera, the surrounding space appears to be a sphere centered on the camera. The process of taking a picture projects this sphere inward onto a flat (planar) surface. This surface could be film or a digital sensor representing a planar surface. Fisheye-Hemi provides an improved way of mapping the surface of the sphere to the planar surface.

In Summary…
The fisheye lens (depending on the camera sensor size) can typically capture a full 180 degree field measured from corner to corner of the sensor. Release Notes:
