Focal Lengths and Different View Points
For this exercise I took two photos of my partner down on the rive. It was a sunny day and I did not realise the poor quality of my pictures until down loaded on to my computer and found that my settings must have been wrong on my camera. As this is a learning exercise I decided to use these anyway. The picture on the left looks over exposed and the one on the right is spoilt with camera shake.
Both frames were taken on Aperture priority on f22. The first frame was taken on my short 18 to 55mm lens at a setting of 18mm standing close enough to nearly fill the frame. The second on my longer 70 to 300mm lens on a 300mm length standing way at a distance until the person looked similar in size.
The differences in the two pictures was quite surprising to me at first until I thought about why the backgrounds looked so different. The shorter lens (18mm setting) gave a feeling of depth to the whole picture with the bridge in the distance and the river disappearing as far as can be seen. The second picture taken with the longer lens (300mm) brings the foreground and the background in to one with a magnifying effect to the background. This made it look as if he was almost under the bridge and cut out the river altogether.
