Reflection -Aperture and Angle of View

In today’s session, as a group we discussed the importance of aperture and how the angles in which we take an image can change the whole tone, distance and professionalism of the image. Aperture is a massive part of the exposure calculation, when taking my own images I will have to consider this as it will have a great impact on whether the image is of a high professional quality. With the aperture restricting the amount of light entering the lens and image can become over exposed or under exposed. For my images, I have to make sure I have the right light balance as it changes the appearance of an image. Today, I learnt that the F.stop number refers to thickness of the black shutters within the camera which is there to blocking out certain amounts of light. As the aperture gets smaller there will be more depth, When the hole if restricted the light gets more focused. This means that as a practitioner I can decide what I want in focus and get rid of distractions if you want.

in these images i change the F.stop to create and develop different scenarios. in the first image on the left the camera focuses more on the right hand side hedge. The rest of the image seems much more in the distance and became blurry. The camera settings was set up on F3.2 and the image on the right is all in focus which doesn’t draw the eye into a specify point in the image, this looks much more basic and not as interesting. this image was taken at F8.

Angle of View, Occurs when using different lenses or the zoom feature. From participating in the practical I noticed when I used a wide angle lens with an aperture of f.stop 5.6, the subject can become distorted and will make things look further away than they are. The internal parts of the lens change the angle of the light being captured. The angle of the light when taking my own images is important as I can manipulate the surrounding area and make things appear further away or closer the the lens. to show my understanding i had experimented whist out and about. See the images below

In the image on the left it is a lot you can see a lot more background, the pole seems further away and the ducks near the pond. By changing the angle of view it makes the image on the right appear much more sharper in the face and makes the background appear closer to my subject. I personal like this technique as you can create an illusion to the viewer and they would be no of the wiser. it also helps to take something not so good into focusing much more on the main focus point and not on the background as much. another really good example was the images below, these was taken when we were doing the practical, however our tutor David took these to give a few of us in the group more of an insight into the impact and change it can have on an image. i personally prefer the image on the right as the face doesn’t appear as elongated and there is less background seen within the image and appears much closer to what it actually was. Also i believe it has more appeal as it is much more pleasant to look at as the subject is much sharper.
