Should I be taking my photographs in RAW or JPEG mode? My D50 is currently set to take the highest quality JPEG photos which allows for about 290 photos on my 1GB card. If I set it to RAW, I can get around 130 pictures on one card. I never take more than 130 photos at a time, so memory card space isn't an issue. I'm just wondering which is the most pratical setting... Thanks!
