What is a Fish eye lens?
A fisheye lens is a special type of ultra-wide angle lens. They are small, Ultra-wide, and show a distorted, spherical view of the world, most evident in the curved, outer corners of the photo.
Surprisingly, they work very well underwater. This is because they focus very closely, there are few straight lines underwater, and finally, because of how close you can get to objects; you can capture more sharpness than you would from a mediocre lens.
Below is my own photograph of the landscape whilst using a fish eye lense. I captured the sun in the background which is the main subject within the image, bringing light in the centre. In addition to that, it gives the image a great colour change from the centre to the borders. The fish eye lens gives the photograph a wide angle with strong visual distortion.
Here are some examples I found online, showing the comparison between a normal photo and fish eye. There were shot with a Tokina 10-17mm fisheye and Sigma 10-20mm.

As you can see, the subject is in the centre of the image in both photographs, looking relatively identical, until you move to the borders where the edges become 'wider' and subject smaller.
Properties of a Fish eye lens:
- They are small and compact
- You can get very close to objects, for maximum sharpness and colour
- Large depth of field, which is great for shooting from a very wide angle
Below I have increased the vibrance but decreased the saturation.
Here is the image, with all colour wiped from the picture. I like it, however I prefer the colour as it gives the image more character rather than a mono colour scheme.
