Shutter Speed: example of exposure.

Here are some examples of exposure and the difficulties that can arise when playing with technical issues of aperture and shutter speed. The first image is where a spot light has been used onto a piece of work to create shadowing; I have applied the idea of shutter speed and keeping the sensor open for varying amount of times.

Photo One:
This has worked as a whole, however after leaving the shutter speed open for 4 seconds (PUT IN NUMBER!!) the object has become slightly over exposed in the top left hand corner of the photo. This might be due to a number of reasons: that the spot light was too close to the top of the subject, causing an overload of light into one area; the shutter speed was open too long and therefore too much light was let into the sensor; therefore the aperture could be adjusted to reduce the opening of the lens thus balancing out the light exposure.



Photo Two:

This is an example of the opposite to photo one. Here the camera was changed to a faster shutter speed where the camera was only exposing the sensor to light for 2 seconds (ADD IN NUMBER). There is a huge difference in lighting. The same source of light was being used, the camera has let in less light, therefore the photograph is much darker and dull. To develop on this, I could have changed the aperture so the lens was bigger and f stop smaller, balancing out the smaller shutter speed with a larger aperture.
