You say that, I know one that does for weddings,,,, BUT!!!!!! both dials (he's on canon so dont ask me the finer details of the controls) are set to override settings (I think one is exposure comp the other is set for apature).
and I can certainly see the logic behind it as general exposure will always be near enough as you want it and you just compensate for how you want the image to come out.
Also nice photos and thank god at Waterton you took the image from the car park,, I see so many posing professionals (using the polite term) shoot down from the stairs facing the car park and it looks HORRID!!!
I also have to add, that you need to think more about posing the models and over all composition, frocks can make them look frumpy and sat down can make brides look like they fell down a hole so look to show figures better (done with body position, positioning the arms and the bouquet if a larger bride) and the hole comment, always try and make sure the toes of the shoes are on show,,, it breaks up the image on a concious and unconscious level. and never sit people plonk centre of an image unless its a group as your pretty much stuffed for granny understanding artistic license.
