Shutter Speed and Aperture


Shutter speed & Aperture 

Below is a contact sheet of my shutter speed and aperture photos. From these photos I chose the best examples of each. 





Shutter speed


The shutter speed is how long the shutter is open for. It is recorded as a fraction of a second. It also controls how much light enters the lens as the longer it is open the more light enters. a large fraction such as, 1/1000 means the camera will capture the image quickly freezing motion. A small fraction such as, 1/4 means the shutter is slow and produces movement lines. This is often used for waterfall and sky movement photos.

Today I went out and shot some images with the camera on the shutter priority mode, to experiment with a fast and a slow shutter speed. I used the slow shutter speed of 1/4 to get movement line and a less sharp image. The image below is an example of my slow shutter speed image. 
the materials I used were a Nikon D3200 and some models to present an example of a fast and slow shutter speed.
I first went out with the camera to shoot some slow shutter speed images. This image below was done using the shutter speed of 1/4. It shows clearly the movements made within the time.


I then experimented using a fast shutter speed to capture a more in focused and sharper image. I used image settings of 1/1000. The image below shows an example of what i captured. I feel this is a good example it shows a freeze in time and there is no blur.

Aperture

The aperture also controls how much light enters the lens but mainly the size of the hole in the lens. The aperture is recorded in F stops with a f in front of the number. The smaller the number like F1.8 means the aperture hole is wide open this means more light enters. However, it has the control over the depth of field this would mean it has a shallow depth of field where the background is blurred and the foreground it sharp. The higher the number like F22 means the aperture hole is small and it has a deep depth of field where the whole image is sharp, this would be used in a landscape image.

I then went on to experiment with the aperture priority mode, focussing on more close up images and details. These images were an experiment with deep and shallow depth of fields. I experimented with f4, where the aperture hole is open wide. However, only the foreground is in focus, the background is out of focus and blurred. This setting would be used for close up and finer detailed images to creates a shallow depth of field. Below is an example of f4.5.


I then experimented with around f32, where the aperture hole has a smaller diameter which lets less light but puts the whole camera frame into focus. This produces a large/deep depth of field. This would be used more in landscape images. Below is an example of a deep depth of field where the whole image is in focus.



I think overall my work came out well, there is a clear difference between each of the different settings. However, I think the difference between bigger and smaller apertures could be more vast. I feel I could have shown a better understanding and clearer example through a landscape image.

Paul Hill Digital Research Paul Hill was born in 1941 in Ludlow, Shropshire. He has worked for a newspaper as a reporter where later he became a freelance photographer in 1965. He has worked for many big companies such as, BBC, The Telegraph and The Guardian.  Hill and his wife were the first to open a residential photography workshop in their home. They live in the Peak District where he travels all over the country to teach and perform workshops in places like Shropshire, Cumbria and Nottingham. Paul Hill is very passionate about photography and he has even been a lecturer at Trent polytechnic in 1974. 1994 Paul Hill was awarded a MBE by the Queen for his services to photography. He produced his landscape project during 1979- 1989. A lot of Hills work was taken in the Peak District where he lives. This image presents a countryside field divided by a stone wall. Where the fields are on a hill a big puddle has evolved in the rain over time. In the right hand side field there i...

Panoramic Experiment

Image
Panoramic Experiment  I went out and shot a series of photos which overlap each other. I experimented using the camera portrait and landscape and also taking straight portrait images and taking landscape overlapping images, such as the last two. Photoshop > automate > photomerge Then select the photos I wanted to use and photoshop merged them together.  I then experimented with the different themes such as, reposition, collage, perspective, cylindrical and spherical.  These different themes changed the way the panoramic looked.  Theme : Collage I like this theme of editing as it doesn't make the photo look spherical. It makes the image look like a wide angle lens. I think this could be refined by extending the view and making sure the final images line up. Theme : Spherical This image looks rounded. I don't like how it looks stretched and further away. I also don't like how the final outcome of this image because to loose the white...
