Start READING up on the subject and learn more on the terms you'd need to understand, e.g. lighting and how the 3 ratios affect each other.
Next up, budget yourself. Photography can be expensive as you add on more and more gear.
A basic beginners kit (can start from anywhere around a few hundred to thousands, depending on model and wether first or second hand)
Lenses (you'd add more along the way, factor for that later on)
Dry cabinet (with our high humidity in SG, it's a strong requirement unless you wish to risk your lenses being infected with fungus, again cost varies to size of cabinet)
Cleaning kits (get a basic cleaning cloth and soloution and a blower, the rest can be added on later)
Accessories (tripods, remote release, external flashes, more memory, etc.... all these require more money)
So... plan and see how you can fit your basic stuff into the budget.
