I think the third is my favorite. He doesn't look very excited to get married. You did a nice job though.
#2 you captured her eyes beautifully but he kind of has "raccoon eyes", maybe some fill flash would have helped that. I think you did a great job!
You had your work cut out for you with that guy. She looked happy to be there though, you have wonderful shots of her. I'd have to say #3. He's not frowning in that one ;-)
The bokeh is interesting - almost looks like a mirror lens or something except its missing that characteristic donut shape - what were you using on these? His chin is a little close to the crop on the second shot - but her eyes are out of this world! I generally like the color in the images a lot. He definitely does not look happy in most of these.
Canon EF 50mm f1.8 II? I use that lens a lot - interesting that the look wasn't that familiar to me.. Maybe I have an uncharacteristic unit. It's a tough lens to use I've found - autofocus is a disaster 50% of the time. Anyway, great shots!
Just because he doesn't like getting pics doesn't mean he doesn't want to get married. I had a guy like this a while back. He loved his girl to death so he agreed to do pics and even after me knowing him for 5 years, he would clam up every time the camera was in front of my face. Nice job on the pics, I know men can be uh, difficult
