As a leftie you just get used to doing many things with your right hand, as most tasks are simple enough to be accomished with your non-dominant hand. Using mice, camera buttons, etc.
Using righty oriented tools as a lefty often has great perks. I know I'd rather have my dominant hand doing the focusing than just pressing the shutter button, for example. I think we lefties got the better end of the deal with cameras! 😉
