- The 72dpi image is poor quality and looks pixelated as well as jagged. There is very little detail seen in this one, compared to the 300dpi and 1200dpi. The 300dpi is clearer although parts of the image still appear darker. The line edges are also smoother in comparison to the 72dpi with no “jaggies” aka “aliasing” evident. The final image, the 1200dpi one is obviously the clearest, the detail is more obvious and the darker parts from the 300dpi image have begun to appear lighter.

- The 72dpi image is pixilated and of poor quality, the lower resolution has made the text unreadable and outlines of the images jagged. The 300dpi is an improvement, although the quality is still less. The image appears a little grainy and darker, however, the edges are smoothed and the text legible. The grain is gone in the 1200dpi image and the image is a little lighter and smoother.

- The overall image is clear and the dark areas solid, however, some of the texture from the paper towel is visible around the outline and spots on the inner and outer parts of the image.
This exercise was to explore the different quality settings of a scanner and learn how scan various types of images and how the dpi settings can change the quality and appearance of an image.
