Nature and Landscapes are my favs !

i personally love them all. I am an "emotional" photographer. I will photograph depending on my mood and my mood also influence the styles I will be photographing.

I'd say landscape and nature are the top.

Macros, nature, landscape, action, b/w (in descending order)

landscape and nature! i could never get tired of them!

From what you mentioned I love nature, action, architecture. Besides that I love people just being people, moments from the life of anyone who focus an image; an instant of poetry. Also it's great when photographys come with a story :D
