I chose to juxtapose these two objects, because they are compared from their age. On the left, you see an actual old calculator, being compared with the modern day touch screen calculator app found on most smartphones today.
I decided to choose these two because they are both soda cans that contain cola yet they are so differently marketed and displayed like polar opposites of each other, with the red Coco-Cola can being so contrasting from the blue Pepsi can.
Juxtaposition of the colors of soda cans evokes a more immediate visual response
The other one is more subtle
good work
