Hi Jj, maybe you might wanna read the manual that comes together with your camera for a start before heading down to any libraries or bookstores.
Think it should somehow answers quite a few number of questions regarding different shooting method and settings. If starting from scratch, you need to learn
how to walk before you can run, or even fly in days to come. So take one step at a time.
Happy shooting and welcome to the Club!!
Shoot first, think later
