ART PROJECT: ROSIE AND I COMPRESSIONS

In class we were assigned to resize our art project photos into eight different compressions and compare the significant differences between each exported image. 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 (181k)

quality (50) size (81k)

quality (25) size (47k)

quality (0) size (23k)

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 is not of best quality sense the natural filter of the image is of a grainy texture. 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. 

GIFs

color (256, not dithered)

color (64, dithered)

color (16, dithered)

For the various images above, the major difference I saw as I decreased the colors and dithered the image was the dulling/decreasing of color definition. I specifically saw this trend in Rosie's red bandana as the initial photo is a bright red and by the third compression the red is a dull, almost deep orange color. Another significant difference that I recognized was the shadows on both her arms and shirt became more bold in colors and lost the blend between the different shades found within these parts of the image.
