AnglerFish

Photographers who own fisheye lenses are generally really happy people. Mostly used in architectural photography and landscapes, they can even take portraiture to an entirely new level, the bottom line being that it is a lens type that allows you to experiment a great deal with composition and lines.
At times, those great distortions that fisheye lenses create can backfire on you. Similar to wide-angle optics, fisheye tend to greatly exaggerate the shape of objects placed at the sides and corners of a shot. The best example would be to take a group photo with a fisheye lens and see how it distorts the people at the sides leaving them with an unflattering figure.
To help you out in scenarios like the above and others where you feel that the fisheye effect is preferably removed, you can try AnglerFish, an application especially designed to help you correct vertical and horizontal projections in photos taken with this lens.

Uncluttered and straight to the point

From an interface point of view, AnglerFish is as user-friendly as can be. The layout is well designed and grants you quick and easy access to all the settings and adjustments.
Center placed is the image preview section to which a more than generous space has been offered and at the sides and top you find sliders and menus which provide everything you need.

Correct fisheye effects in a simple manner

The entire process of fixing a photo is challenge free. It comes to your advantage to have a bit of know-how in editing but since it’s mostly sliders you’ll be dealing with, and you do get an instant preview of the image after a modification is made, things should run smoothly from start to finish.
It might take you a while to get things just right and there is a strong chance that you won’t be able to fix everything but the result do come out looking better. Moreover, workflow is greatly enhanced since AnglerFish allows you to choose the lens model and the camera body that were used to take the photo.

A handy fisheye projection fixer

With the above to consider and a lot more to discover in the details, it's safe to say that if you’re looking for a tool that can correct some if not all the unappealing distortions in a photo taken with a fisheye lens, then you can certainly try AnglerFish.
