As Bernd said, JPEG is fine for the time being. You will want to master in camera before worrying about any post processing (many today think post processing is enough to "save" an image and don't value the importance of getting it right in camera). Master composition and proper exposure (ISO, aperture, shutter speed).
Once you are able to capture interesting shots, then you can worry about hand developing a RAW file (where small fixes and adjustments can be made and the image can be "developed" by the artist instead of the machine).
I'm not going to make any new friends with this contribution. I reckon RAW should be left to photographers that operate on a commercial level, that have to satisfy the demands of a client. Sure some enthusiasts might want to explore it to help give their images an edge in competitions or might just enjoy tweeking images more than the rest of us, RAW is an option, its worth learning, BUT its not a priority for anyone just starting off.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
