I think this is what they call 'noise' in photography, but I took this picture a long time before I had heard of 'noise'. It was also the time when you had one roll of film in your camera and you used it under whatever circumstances you wanted to take a picture. A high ISO would give more noise, be more grainy. This picture was taken under low light conditions and I had to open the aperture. Still, I have always liked this picture taken through an open door in Rome.
Camera: my faithful Minolta, which is gathering dust now that I have gone digital.
