A little confused regarding raw and jpeg. I read on here and in magazines that photographers use raw more often than jpeg. Why is this? Does shooting in raw give you a better picture with better quality ? And when is the best times to shoot in raw and same for jpeg? AND also on my Lumix FZ38 it also has Raw + Jpeg as a selection. What is this? Does it shoot in raw and automatically convert to jpeg? Sorry for all the questions but i'm a tad bit confused. Thanks in advance.
