RAW is very forgiving. I was photographing a farm woman in Ecuador cooking over a small fire and my fill flash didn't go off a few times. I was about to delete the RAW files but decided to play with the curves first because I like the composition. It turned out that the image, although underexposed by two stops, was better than the fill-flashed images because the fire was the only source of illumination and it looked more real.
Digital makes it so much easier. No bricks of film, no worrying about airport X-rays, etc.
I sold all my medium format equipment in 2005 after Canon came out with the 12 megapixel EOS 1Ds.
I drove a taxi at night during my last year at BU and then for another 18 months after graduating in order to buy cameras and pay the rent while I tried to figure out for myself how to freelance.
Everyone thinks it would be great to work for National Geographic. So did I.
Scientists are usually nice, organized, logical people who are very cooperative. I always learn a lot of science while shooting science stories and it helps to be able to speak intelligently to a subject about his or her field of work, i.e., do your homework before the photography.
I've heard Braggadocio about excess baggage charges, multiple unused hotel rooms, and rental cars held unused for long periods of time, which makes me lose respect for certain photographers. Sometimes it's worth it to spend money on a good idea, but wasting money makes me ill.
