Photobashing is the process of taking various separate images and combining then into one, using photo manipulation – the process of using filters and other editing techniques – to ensure they blend and fit together. This can be used to quickly create a visual representation of an idea, with much less effort than fully drawing it out, to get a feel for how it would look.
I got the images I used to make this image from the website Unsplash, which is a source of royalty-free images.
