DESTINATION PROJECT COMPRESSIONS

In class we were assigned to resize our photo into eight different compressions and compare the significant differences between the images where we placed ourselves in a place we had never been. Below I will first compare the various exported JPEG images and following I will compare the exported GIFs.

JPEG:

quality (100) size (457k)

quality (75) size (135k)

quality (50) size (69k)

quality (25) size (41k)

quality (0) size (19k)

For the various images above, the major difference I saw as I decreased the quality of the image was it became more blurry/distorted. The picture initially already had a blurred background, so by the last image with the quality of 0 the grand canyon backdrop holds cartoon characteristics as the distortion makes it look animated.  Definitely comparing the first photo of 100% quality to the last one with 0 quality I could see how the pixels definitely became more blurred and the image as a whole and especially myself became greatly distorted and not a clear image as it used to be.

GIFs

color (256, not dithered)

color (64, dithered)

color (16, not dithered)

For the various images above, the major difference I saw as I decreased the colors and dithered the image was the dulling/loss of color definition and variation. The significant change I saw from the first photo to the preceding photos was the as the color was decreased, the photo loss the red and green coloring. Specifically seen in the last photo, when the color is set at 16 the photo sticks to strictly gray, browns, and blue family colors.
