For the reason I listed. Shooting a high contrast scene the flash is fooled which is why adjustments need to be made, You can't stick with ettl without it being fooled at some point.
I tried manual but like Joe said, you are shooting the bride and getting ready and you have everything set to manual or camera on manual and flash to ettl and then, the door behind you opens up letting in light you never set your settings to and bam, there it goes, photo missed. Whereas if you were in P with AE Lock on shooting and something happens to change the lighting all of a sudden, you just let go of the AE Lock and it gives you the new reading and you keep on shooting.
I'm just trying to simplify things since I had to fire my 2nd. shooter so I've got it all on my shoulders to get all the shots and quickly.
Exactly the same will apply if you are shooting in Av, but without the shutter speed issue that you are complaining about with P.
Weddings are not easy things to photograph, you need to have control over your exposures. As a person shooting weddings professionally you should have the knowledge to be able to quickly and easily adapt your settings to the situation, yet you don't seem to understand how the different modes work. You seem to use P mode because one wedding photographer you admire shoots in P and it works for him. It doesn't work for most people, and you yourself are frustrated with the fact that you don't have the control you want, yet any suggestions to switch to another mode are responded to with arguments as to why you don't want to do that. Arguments which make little or no sense such as the one bolded above.
I don't doubt that P works, and seems to work well, for Buissink. However, he probably has some methods in his workflow which allow it to work well for him. That doesn't mean it will work well for you, if you don't shoot the same way he does.
You can either accept that P has some limitations and adopt a workflow which shoots around them, or do as most other wedding photographers do and use another mode. The most important thing though is to learn how your camera works, so that you don't find yourself complaining that the camera won't pick the right settings. Having the right settings is your responsibility, not the cameras.
