Hi
@William1986nikon - welcome to TP and to Nikon too (the best brand lol)
My groups (Weddings) are always all done in the same way - its simple, and I like simple
Focusing - single point AF using the centre (best) focus point on the Bride on focus-release. If its a bigger group so people are standing behind her then I'm usually on my 35mm and f5.6 is plenty of depth of field; is its a few people in a line then I'm more likely to shoot that at f4 or even f2.8 on my 85mm, and as they are all in the same plane of focus they are all sharp enough while allowing me to lose the background a fair bit
I tried the back-focus button and hated it. I never use continuous focus and haven't even tried tracking etc. Effectively, I still shoot in the same way I did 20 years ago before all this wonderful tech was invented, its not that I'm a Luddite, but rather its always worked for me this way and still does as I don't shoot tricky subjects
If the Bride is moving towards me then I still use the focus-release feature rather than continuous focus as it works perfectly well anyway as Brides don't move very fast!
Metering - eval/matrix as
@Phil V said. It solves the issue of taking a metering off a Bride's skin and then thinking about how white/tanned/black she is as to how that's affecting the metering - I NEVER spot meter anything. My 'safety' feature is that I do always have the camera in review to show me the image on the back of the camera and I have Highlight Alert (Blinkies) enabled, where I aim for a hint of Blinkies on the Bride's dress around her chest/boobs. This is as perfectly reliable as I've ever managed as the camera's own jpeg (what you're looking at) shows slight blown whites when the raw file actually still has all the detail I need. Note: if the dress isn't white or very close to white I get the blinkies then dial it back a bit until they stop
Flash metering - Blinkies - I did once own a flash-meter but never used it
What you'll realise already in the aboth is that there's several ways of doing the same thing and the 'right' way to do it is whatever works and that you end up liking best
Many ways to skin the old moggy
Much of photography's techie side is like that - makes it all the more confusing - I mean fun lol
