Isn't it even more racist to replace them in a picture? Being told that your skin colour is too offensive to show sounds a lot worse to me than calling them "white" considering their skin is very white
canon is also a great choice because the ef mount is larger than most other dslr and it can fit pretty much every dslr lens that exists (vintage and new) without the need for an expense adapter that has optical elements. You can even 3d print them
