Does zooming in from a fixed viewpoint change the appearance of things? If you enlarge and compare individual elements within the first and last shots of the last exercise you can see that their ‘perspective geometry’ is exactly the same. To change the way things actually look, a change in focal length needs to be combined with a change in viewpoint.
For this assignment I essentially had to display an understanding of ‘perspective geometry’, and how backgrounds and images change depending on their focal length. I think it’s incredibly important in photography to have an understanding of parallax and perspective – or even just the way things move at different speeds depending on their distance from one and other. By understanding these simple laws, you can integrate them into almost any art form. You have the creative freedom to adapt this knowledge to almost every visual medium. For example in the Square Mile, I used my knowledge of perspective and parallax to create images with multiple fields – I’ve stated numerous times the importance of using photography in a way that makes it seem impactful, separating images into three different dimensions.
Here above is an example of what we call single point perspective, which means there is only one Vanishing point. This type of perspective is usually used in Street photography as it gives the viewer an immense sense of scale. As you can clearly see the buildings at the front are visibly smaller than the ones at the back, however they’re built to the exact same scale. For my project Plasterscene Gems, I used perspective when making miniatures to make the buildings seem much bigger than they actually are. By making the buildings that stand in the background smaller, I was almost guaranteed an increased sense of scale.
For this I decided to use the Blackmagic 4K Cinema camera. Using the kit lens I followed the brief, as you can see the differences in the images are subtle yet noticeable. First of all, as we step closer to the subject in the second image you can see a lot of lens distortion – as the camera’s mount is a full frame sensor sporting an EF mount – yet this particular 18-55mm lens is made for APS-C mounts. This isn’t noticeable when shooting at sharper apertures, but in this particular image you can definitely see some of that distortion coming in. Following this, you can see more background information in the second image, this is because we’re shooting with a wider focal length which pushes subjects further away.
