Just a couple of days ago I got a Nikon D60 and a heap of accessories as my graduation present from my parents (thanks Mum and Dad!). Been playing with it a lot, especially with the excellent SB-600 speedlight.
Tonight I was at a friend’s place where I took about 150 shots, mostly of people. I was using the speedlight as a bounce flash, because I hate the harshness of direct flash. Most of the shots looked great in camera, but when I got the memory card into my laptop to have a closer look, many of them were underexposed, some terribly. Fortunately for me, I had been shooting in RAW all night. Long processing time and big file sizes suck, but they suck a whole lot less than having a bunch of otherwise great photos being unusable because they’re too dark.
I have learned a valuable lesson tonight: If you can, shoot in RAW.
