The image was purely by chance, I believe it came from an internal error with the photography software on my phone which just happened to take place during the image being taken. The image was captured directly within Instagram, so no further manipulation was added.
No other image from the day or indeed before or since has resulted in the same effect, so it is purely by chance that this image exists. The image was taken of my cousins dog playing on the beach on my galaxy S6 edge phone.
