Dave, for the visual cue to how much the over
exposure is, always check the histogram. There is over
exposure in the image.
Some histogram tools in various software have the ability to display lost highlights/shadow in the image via flashing cues for each.
For example if you have a copy of Lightroom you click on the small triangle in the top right corner of the histogram graph and it will show you where the lost highlights are in the image.
Of course other software will vary on how it all works, but it's a good way to get a finer tuned pseudo calibration.
The only other thing I wanted to mention was the slight blue cast in the image. The whites especially in the groom's shirt look to have too much of a blue cast, mainly in the darker areas of the white sections.
This is usually due to a cooler than ideal WB setting in camera and no adjustment made in PP.
If you shot in cloudy conditions, and used AWB in camera, (we know you shot in
raw mode in camera) first thing is to set WB to cloudy and take it from there.
For me, I would set WB in the
raw file from what ever it was, to either
cloudy or about
5700-6200K(depending on what software you're using)
Only because Darren mentioned the background(and he's most definitely right too!
) if you have unappealing backgrounds to contend with, first thing you do with the subjects is to pull them away from the background in the hope that you can get it blurred easily.
