I think the aesthetic thing
All kind of, nature, nude, landscapes, portraits, people, animals,architecture and so on.
I work with analog cameras (still), for color I use the Minolta X700 and for black & white the XD7 and differend kind of lenses from the 16mm fisheye to 600mm with converter and everything between it.
several filters, like the käsemann pol and all regular b&w filters. two tripods, my Minolta chest tripod who I really love and my Gitzo carbon tripod.I have a flash but most of the time I try to work without and use natural light.
