Excellent point! I'm on the brink of going digital, so I'm still using medium format: 11 to 13 rolls of 24 exposure for about 8 - 10 hours of wedding coverage. By the time I end up tossing the shots that either I don't like or are just plain repetitive, the couple ends up getting around 280 or so very attractive, carefully selected, thoughtfully edited 5x5 prints, nicely presented in a preview book.
The fact is you DON'T want your client to see EVERY single photo you shoot that day. At worst, some of the shots will be just plain boring, while many will be simply uninspired and mundane if you are concentrating on volume in place of selective quality. You want your work to look its best, and I really don't believe you will be achieving that by shooting everything in sight with very little mental editing. You are shooting the bride with a fine dSLR tool, not an M16 set on full auto.
Selecting, editing and choosing your shots should take place in your head before you trip the shutter. Yes, I realize there's hardly any extra "material" cost involved when you're burning flash memory instead of film, and just providing CD proofing instead of real photos, but why do you want to bury the client in information? IMHO I just feel that 1000+ photos of the wedding day is just nuclear overkill.
Stop and consider: What really makes a better presentation to the bride and groom - (1) More than a 1000 ok images mixed in with some pretty good shots that will take a lot of time to review, or (2) just 200 - 300 carefully edited, really super photos that will really standout in the book?
I often have to phone the newlyweds a couple of times just to get them to return their final order to me in less than two months, and thats with less than 300 proofs. Why would I want to make this any more painful? Obviously this method works very well for me and your mileage may vary. But if you are not getting your orders back in a timely fashion, or if you are getting no reorders at all, then you may want to rethink your approach. End of rant.
As photographers we THINK we are doing our wedding clients a FAVOR(?) in giving them thousands of photos. Think again, guys'n'gals! Our daughter got married and was provided over 3000 photos, and it took them MONTHS to get the proofs (the guy had to postprocess them a certain amount for presentation, not necessarily fine tune to final quality level) and almost as long for the new bride and groom to look through all the photos and then choose!
