I usually shoot on jpeg-fine on my d700...my files come out to be around 4-5mb after they are processed in lightroom.
I am a photojournalist, so I rarely have a need to have huge poster size prints. I came across a couple who bought a photo from the paper and wanted something like an 18 x 24. When they went to print, they were told it was not a big enough file.
I am not in the print business, so I am trying to figure out why my d700 has tons of MP's but I only come up with 5mb size files. Honestly, I had never thought about it before, because 5mb with 300 dpi is sufficient for what I am doing.
Even when I shoot in raw (and I rarely do that) I am around 7mb....Is there a setting I am missing, or just a piece of info that I don't get?
I would like to blow up some of my travel prints but now I worry that they too will have the same issue of too small of a file.
