With absolutely no disrespect to anyone I find the concept of taking between 600-4000 images for an event such as a wedding etc sheer insanity
Surely when doing an event like this the person taking the photos should be at such a level of expertise that no more than a hundred would be enough for an average wedding??
During the 80's I did many weddings (film) and the average bundle bought was for 72 pics plus album - with enlargements extra.
I never went to a wedding with more than 3 rolls of 36 (35mm) and enjoyed good success for many years without hiccup.
Fortunately this has carried over to my digital shooting (only amateur now) and never have to shoot a thousand pics just to get 10 keepers.
If I did I would be spending a lifetime in front of a pc just going through images and choosing.
