I always prefer available light over studio light simply because it gives me more realistic ambience and color. I feel that studio photography is too fake as it is staged!
Getting started with available light photography is easy too. As you can see from these two example below..just find a huge/large window. The light from the window is one of the best light there is for photography.!
Camera: Olympus E3
