I walk three hundred metres from the garden to the awaiting bride. This is not the time to be fussy about the light or meticulous about posing her. All that's important is her happiness and excitement. Any problems can be dealt with after the event. Indeed, given this is the first encounter between the bride and the photographer on her wedding day, it is vital for the photographer to appear to be confident and any fiddling with camera dials will cause the bride to doubt the photographer, and that look of scepticism could contaminate every subsequent photo.
This is the photo as it was shot.
This is the photo after tweaking it.
Before you take any photos, tell her she looks wonderful - she will, but it's nice and a relief for the bride to hear it from the person who is going to record the event for posterity.
