London-based photographer Joseph Ford isn't your average photographer. He creates optical illusions by combining objects that wouldn't necessarily match if they were viewed separately.

"Whether it be with changing scales or with blending objects together, I'm always looking for new ways to create this sort of illusion," Ford tells MNN. "and sometimes inspiration will come by chance, seeing one object and mistaking it for another, and then figuring out a way to turn my mistake into an image that will inspire other people."

Ford was inspired to create his "Knitted Camouflage" collection after meeting knitter Nina Dodd. The first project they collaborated on was the red sweater on a bus photo.

The first step in creating these photos involves Ford scouting out locations that can be easily knitted into clothing.

"They have to be eye-catching but also simple enough to be able to be knitted."

Ford also has to find locations that are permanent because it takes Dodd several weeks to knit each sweater. The sweaters have to match as close as possible in color and in design to create the optical illusion.

While most of the photos show knitted sweaters with simple designs, sometimes it requires more to create the effect. Dodd also knitted these pants for this model, who is sitting at the exact right angle to pull off this image.

Not every sweater is simple in design though. Ford and Dodd pushed the envelope with their talents by finding backdrops with an array of colors and perfectly knitting a coordinating sweater (even for a dog!).
