I look a load of photos of this one wall from left to right just pivoting on where I was standing, not moving. The joiner I made has a wide angle effect because of this. Im not happy with the saturation and levels so I'm about to edit this further.
I've been interested in fish eye and wide angle photography for a several years now and i have owned a lomography fisheye camera for a while now. After buying my Nikon D50 I wanted to convert it to fish eye some how as i know lenses are expensive. Ended up making one from a lens cap and a door spy hole. These are some shots of the 'lenses' and some examples.
