Shutter speed and Aperture

Slow shutter speed combined with panning the camera can achieve a motion blur for moving objects. In photography, shutter speed or exposure time is the length of time a camera's shutter is open when taking a photograph. The amount of light that reaches the film or image sensor is proportional to the exposure time.

Here is an example of shutter speed, as you can see by the photo the bigger the number the more it catches the movement in one photograph.

Aperture

In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture of an optical systemis the opening that controls the cone angle of a package of rays that come to a focus in the image.

It is a dimensionless number that is a quantitative measure of lens speed, and an important concept in photography.

Planning My Idea For Final Piece

After thinking about what to do for my final piece, I decided to take photos of whatever I felt looked good in architecture. When coming back from a photo shoot of Liverpool Street I sat and looked at my photographs. The photographs I have taken seemed to be very modern, clean and sharp looking buildings. I then wondered about older looking buildings and the contrast. I then went back out and took some photographs of buildings that didn’t look to up to scratch. In my final piece I am going to make an A6 collage of the comparison of the buildings, on one of the side will be the horrible looking buildings in east London such as the MacDonald’s at watney and the buildings along commercial road, such as council houses and old restaurants and pubs no one uses anymore.
