JPG Compression and File Size

Q100 

DISCUSSION

        In this project we used a new filter on Photoshop named cutout; it reduces the color from the image, but what reduces the quality of the image is when you change the image to JPG. Not only did we change the file to jpg reducing its quality but we also went withing jpg and changed the quality of the image even more. When the quality is at 100 the image is viewed the best jpg file. Quality 100 has the largest file size at 57,990.










Q60

   DISCUSSION

       This file was set at quality sixty which does not turn out as horrible as the photo with quality zero, but its still not the greatest. As the quality changes so does the files size. For example with this file the image is set to use better quality that zero so the file takes up more space. (19,377 bytes)    










Q0 

DISCUSSION

        The most noticeable area to see the changes in the quality is around the eyes on the face. This is quality zero which causes the image to be very pixelized, boxy, blurry, and just plain out a terrible image. This file size is the smallest as 5,732 bytes.
