This image was intended as a joke – looking like pseudo-advertisement. The word “fish-eye” for ultra wide-angle lenses always sounded funny for me. I have already seen some similar photo-montages on the internet, but I wanted to try something similar myself. All work done in GIMP, additional details with text were made in Inkscape.
The beautiful background photo is Underwater Light and Bubbles by Della-Stock:[link]
The lens photo was originally Samyang fish-eye lens
PS: the name „Vokoun“ is derived from a name of the freshwater bass fish in Czech and is also related with Czech slang word for „eye“.
