Interpolation, as described on pages 50 and 51 of the text, is an interesting concept. Understanding how the image relates to the "you" is very important to understand for someone who is going into the fields of graphic design, marketing, and advertising. 

The meanings that the producer of the work may intend may not necessarily coincide with the meanings that the viewer gets out of it. One has to consider cultural contexts. As said on page 55 of the text, "meanings are the product o a complex social interaction among image viewers, and context". This is also an important factor to take into consideration, for those going into the fields of graphic design and marketing.

Beauty, or what we find aesthetically pleasing, does not reside within the image itself, but is culturally determined, according to page 56 of the text.

It is interesting, as well, that institutions instill in us what defines good, or bad taste. Taste is also defined by class, according to page 60 in the text, as in "high brow" and "low brow" art.
