Recording Blur

Recording Blur 

SLR Camera 

Aperture

  

       Achieving blur through Aperture settings means having a large aperture (small F stop). This gives you a Narrow Depth of Field. For example 2.4, 4, 5.6 

Shutter Speed 

        Achieving Blur through Shutter Speed means increasing the amount of time the shutter is open. When having a small shutter speed it freezes time. Any shutter speed over 1/30secs can show blur. 

Slow Sync Flash 

        Slow sync flash is just a fancy term for using your flash with a slow shutter speed. It helps you keep your subject sharp while capturing motion or a dark background. 

Blur 
       For the first part of this technique experiment I tried to record blur outside. To do this I stood by a fast moving road with my camera on a tripod trying to record the motion of the cars. It was hard at first to try record this without the image being overexposed however when changing the exposure balance I managed to get some correctly exposed images. 

        For the images above I didn't use a shutter speed that was too long, I stayed around the 1/15secs to 1/8secs range. This was to ensure that I captured the right amount of movement as if I had used 1 or 2 seconds there would've been too much and it would've been unclear as to what I was taking. Throughout the shoot, I was using ISO100 to keep the light sensitivity low to ensure that they weren't overexposed. 



Slow Sync Blur 

       For these images above I used the studio with a soft box flash. Whilst in the studio I decided to use the dark background in order for the blur (which usually shows up quite light) to show. I really like the effect that the slow sync flash brings it makes the photos look slightly fine art as it is unclear as to what the light is across the image. I definitely found it easier to achieve blur in the studio than outside because most of my images had a good exposure.
