Techniques Camera Controls and Blur

Camera Controls and Blur

Definition: Blur is the apparent streaking of rapidly moving objects in a still image or a sequence of images such as a movie or animation. It results when the image being recorded changes during the recording of a single frame, either due to rapid movement or long exposure.

William Klein

He was born on 19th April, 1928 in America. He was a French photographer and used unusual photographic techniques. One of these was working with blur as it allowed him to react instantly to something that was happening around him. Therefore the first thing he didn't use was a tripod as a result his photos had a tendency to not be straight.

The fact that this photo isn't straight (in line with the road) you can tell that he has quickly taken the photo. The blur is shown in the man who is dead centre of the photo as well as the child in to the left. The blur is due to them walking which for a normal person who is walking rather slow would be a around 80 beats per minute. The man in the black suit has obviously noticed the camera and stopped to smile which is why he is in focus.

Camera Controls

The main camera controls:

Aperture:

Large aperture = Low F Stop = Narrow depth of field

Small aperture = High F Stop = Wide depth of field

Shutter Speed: means the timing and duration of opening and closing of the shutter curtain at the back of the camera. A fast shutter speed will freeze action will slow the speed creating a blurring effect (motion blur)

The relationship between the shutter speed and the aperture

This gives the ample ISO setting.

ISO: 100, 200, 400, 800, 1600

Analysis

This technique went really well as the go the desired effect of the motion blur. This is due to using and understanding the camera settings i was using in order to create the photos. In the first photo I tried the easiest one to capture as i could make sure that the subject was moving fast enough for the blur to work and it worked first time. This most likely happened due to the long shutter speed as it would show any movement that was made. In all the photos the background remained still and only the subject was moving. This showed good camera control as there was no camera shake. In my opinion i like how in the photo you can still make out what the subject is doing.

Will I use this technique in my work?

I may use this technique in my work in order to help blur out the people as they walk. This will allow the main focus of my work to remain still while taking out distractions like peoples faces.
