First wedding post - D70+SB600 comments?
Another SB600 fan (with D50) here! Attended family wedding yesterday so your post struck a chord.
I really like the portrait of the bride and first dance, and the crops show you captured wonderful detail.
With the other two shots the lighting was obviously very tricky (eg bright sky in background) so you've ended up with some 'hot spots'. White dresses don't help! The group shot in particular has a lot of blown highlights.
Maybe dialling in a little negative exposure compensation and/or recomposing to avoid bright sky in background might have helped for those shots?
