At a family wedding last year instead of buying disposable cameras for everyone to use, then having the faff of collecting them up and processing them, they signed upto an on-line service where everyone used their smartphones, could upload to the app and anyone could use the photo’s thereafter. You can also upload video. Can’t remember the name of the app, but i’m sure it’d come up on google.
As for traditional photographers, try a keen amateur. We did, they were cheaper, took loads of photo’s and gave you them all at the end – hard copies and memory sticks, and they pass over copyright so you can get them reproduced anywhere you like. Photo’s were as good as any i’ve seen. Downside is you need to sort out an album yourself, but really, who has ever got out their album and looked at it once it goes up in the loft after the wedding?
