Forget all what you can see in the movies and documentaries as those are about guys who are photographers by profession. This is why they need many things. But you on the other hand, have only started to learn photography. Therefore it’s more than enough for you to have your cam and nothing much with you. Your teacher will probably give you advice on what camera to buy (probably a cost effective Canon, Nikon or Olympus will perfectly do). Have it in its respective holder, then simply carry it in your handbag or bag. Forget about all the expensive accessories, only buy those unless it’s absolutely necessary. The most important thing for all photographers, is to be mobile and to be ready to react as fast as possible. So, have your camera at a place from where you can easily get it anytime you want to.
