How to Properly Change a Lens

I know I know, you’re probably saying: “Brian, come on…I know how to change a lens!”. And I’m sure everyone out there knows how to change a lens, but so often have I seen it done incorrectly, I thought I’d put this together simply as a reminder for y’all as EVERYONE loves clean sensors!
