Picture of Computer Back

Computer back taken Further Away

Comments:

Here are 2 shots of the back of a computer at different distances away from the computer. The objective is to see how the camera captures the interesting lines and patterns on the back of the computer.

Comparison of Edges:
- Zoom-in 1 shows a vertical edge of the right side of the computer from the 1st picture. Zoom-in 2 shows diagonal and vertical edges of a drawing in the background of the second picture, which was taken further away from the computer compared to the 1st picture.

Zoom-in 1

Zoom-in 2

In zoom-in 1, the edge highlighted by the red circle is about 3 pixels wide. In zoom-in 2, the diagonal and vertical edges of the drawing are also about 3 pixels wide. Note that the second picture was taken further away from 1st picture, so the object and edges in zoom-in 2 is further behind the edge in zoom-in 1. Yet, the edges in both cases occupy  3 pixels wide. The Sony Ericsson S700i has edges that are 2 pixels wide.

Noise:
- In the second picture, the top of the black file on top of the computer is quite noisy.

Checkered Patterns has False Colors and are Blurred:
- There are false colors on the checkered patterns of the fan when picutre is taken further away from computer compared to the first picture. Also, the edges of the checkered patterns become slightly blurred in the second picture.
