They include but are not limited to these:
Aerial ==> From a plane, helicopter, balloon or other airborne device.
Animal, Pet ==> Pets and their relationships with humans.
Black & White ==> Not simply photography without colour, black and white photography explores shapes, tones and textures. Shadows and highlights become much more important.
My personal favorite:
Urban, Industrial Photography ==> Love to Emphasize urban people and their environments through colour, Black & White, blurr, details, fashion and lifestyle.
Here I made a small gallery, a gallery of pics that I found browsing the net. This is the type of Urban, Industrial Photography I love. One day I will be as great as these photographers. I can very much appreciate these pics now that I'm starting my love for it.
