My shooting style is not spray and pray. Weddings are about emotion and a lot of what I shoot is documentary. I often take burst shots of the same composition in order to get that one decisive moment, and it works. The subtle differences between body language and emotion in photos taken a millisecond apart can be staggering.
Pookyhead, your calculations on time spent per photo don't take into account that oftentimes groups of 5-10 shots happen in just one second. It's a deliberate technique and one that is employed by many of my favourite photographers - Fer Juaristi, for example, told me he sometimes shoots 5-6k per wedding (more than what I and my gf will shoot together in total). Digital affords me the ability to do this, so why wouldn't I take advantage of it when the results justify it?!?
I said I shoot 2-4k images per wedding, not 4k minimum. Looking at my last 3 weddings here, my shot counts are 3,451, 2624 and 2890. When coupled with my gf's shots we (note that I did say WE in my post, before) regularly end up with over 100gb per wedding before we cull.
Storage is of course going to be an issue with such volume, but the differences in 24mp and 36mp become more significant.
We retain around 6-700 images on average, which is roughly 10-15% of what we take.
I use two camera bodies also, so no, I don't put 200k on a camera over 50 weddings but if I did it wouldn't bother me at all. The D800 is the least practical FF nikon camera that i've used at a wedding, I'd love a D710 to address the issues that I and other wedding photographers have with it.
