The question of what fine art photography is has no easy answer. There is no universal meaning to what it means and we all have our own view. To my mind it is something that the photographer creates in their mind. The image should be pre-visualized or visualized when taking the image. Some people will see the image in black and white or sepia or vary the scene in color, it is a personal thing. The image should have some artistic or aesthetic quality to it.
As I have moved more into the world of landscape photography my work has moved more to long exposure photography. The effects that this has on water and clouds really appeals to me and gives me the feeling that I want in my photographs. One person recently commented on my images that they were mysterious and dreamy. Maybe that is a reflection on me and the way I see the world. For all the ugliness in the world I do like to see the beautiful side of it. As people say, I live in my own world most of the time, this is probably correct but its a happier place than the real world.
The image that I have added was taken at Betws Y Coed in Wales. It is taken using my 10 stop neutral density filter to give me a long exposure. The exposure was 30 seconds at f22 with the camera set at 100 ISO. Hopefully it has given that dreamy quality that I like to the image. If you are taking fine art based images then do not be afraid to experiment. Find out what your equipment is capable of, it will allow you more opportunities to be creative. You will be amazed at what some equipment allows you to create. The best advice that I can give is to learn to use your camera in manual and keep an open mind.
