I know there are many discussions online about this topic, so I humbly apologise if I missed the answers to my following questions.
As I stated in the title I am right handed but left eye dominant, leading to me naturally using the viewfinder with my left eye. Out of convenience reasons I have the trigger (right hand) up when taking verticals. This means the camera covers most of my weaker right eye.
Now I've read about the advantages of having both eyes open to track movement outside the viewfinder. Leaving the eye open isn't a problem but I can't see much past the camera.
My questions are now:
Is taking verticals with left eye and right hand up considered "bad practise" in general?
Would you recommend switching to having the trigger (right hand) down as to to solve the field of view problem (seeing the camera with the right eye rather than the surroundings)? Even though it's less comfortable to me?
Should I even consider switching my viewfinder eye to right to leverage the camera design (Canon 7D) in my case and possibly also have some vision of the surroundings when doing horizontals?
