Thanks Mark I always thought digital was like shooting slides. You have a lot less latitude in exposure. The reason I could set the camera and light on auto and just worry about the other things, is that the film had a good latitude and as long as i was careful what I had in the foreground the exposure was pretty easy to adjust in the lab.
What I did to lighten these pictures is what I would do in a darkroom. I in effect burned and dodged a little then added a hit of blue. Like you said, nothing we couldn't have done in a darkroom ten years ago. The things you can't fix are composition and like the lady said being able to shoot pleasing looking shots. I am used to a lot more strobe light so the light (color) balance isn't usually a problem for me. Also a strobe hit shot had really nicer contrast in my opinion.
By the way the only time I shot slides was when a customer held a gun to my head and then I bracketted like mad.
When you are ready to shoot a wedding is a matter of opinion. My advice is always followed by shoot shoot shoot. Nothing beats experience. The best experience is to work with a seasoned photographer but that is getting harder and harder to do.
I still say, shoot for the face and let the rest take care of itself. The largest number of complaints I heard about 'other' photographers (never me you understand) was that the pictures were dark. When you penned the customer down, so that you would make the same mistake, it was always you could hardly see the faces.
If you are trying to gain experience, find those folks who would not have a photographer otherwise, and try to learn from everything you shoot. Don't be afraid of critique it is your friend, but only if you learn from it. If you can shoot behind the 'real' photographer at a friend's wedding do that as often as you can.
However all that said, for a first effort, if you had done the digital darkroom (photoshop to you guys) things these prints would have been acceptable in a walmart world... They might not be the ten k wedding acceptable but would have been the gift for a friend acceptable.
