RAW is a waste of time? So, basically what you are saying is that to save time you would forego the ability to get the best out of your images?
Maybe you should try another method besides the "spray and pray" method of shooting if the number of your shots is unmanageable. I don't do that many weddings but if I come away with more than maybe 400 shots for engagement, pre-wedding, wedding and reception I am doing something very wrong. And I have yet to have, in all the years I have been doing things, had a custome who was not very pleased with the final results.
Maybe my philosophy stems from the days when all we had available was film and you actually had to make every frame count. Since digital is "free" you can just keep shooting anything that moves for essentially no extra up front cost or you lose money. From someone who shoots A LOT of modeling portfolios, in my mind it is unprofessional and discourteous to force a client to wade through 1800 images to find the best ones. You did not say in your post that that is what you do, but just sayin'. On a typical 2-3 hour modeling shoot, if I come away with more than 40-50 images again I must be doing something very wrong. I would rather the model agonize over 40-50 images because she likes them all than have her agonize over 400+ (which a lot of GWC's - Guys With Cameras) do because there are so many of them which are pure trash. Models are stunned when I tell them that they will get their proofs the same day for a morning shoot and the next day for an afternoon or evening shoot. And they get their images usally the next day or even earlier after that,
But that's just me, I'm a pragmatist.
