About RAW. I have one year experience with digital. I have one month experience with PP, digital software. It is a whole other realm. If compared to film days (I had 30 years as a photo journalist) it puts YOU in the position of choosing kodachrome 64 or color negative film, then gives you the control of a Kodak labs chemist, and lastly as a darkroom technician.
It gives you power. But, boy, is there a lot to learn. I dithered for months before settling on the particular software I got. And RAW enables you to manipulate all the variables. Jpeg is far more automatic, and simplified and limited. RAW can turn night into day, literally. I think. But, as I saw, what do I know. I'm new to post processing.
