When I do photography I usually do not think about all the technical aspects. For me, as a photographer, it is very important to feel the person I work with. To find his or hers beautiful sides that I want to capture. I am thinking more about the angle, the emotions of my model, about the composition and the background. I usually work with one portrait lens which I almost never change during the photo shoot. And with 3 on camera settings, like ISO, aperture and shutter speed.
I get very involved in the process when I work and can simply forget the time.
I never know about the final result when I start to photograph. I go with my feelings, with my intuition and artistic feel when I hold the camera in my hands.
