Oprah?
| •Let’s return to the world of 2D reproduction and the look
at some of the impact that the computer has had on our understanding of
visual truth. As any photographer can tell you, no photo is completely
objective: contains a choice of subject matter, cropping, work in darkroom,
etc. |
|
| •Bu the issues are much more pronounced in digital
photography, which is really a combination of photography and illustration
(or painting). |
|
| •Some of you may have read about this, now infamous, example
of image editing |
|
| •This was the cover of the Aug. 26, 1989 issue of TV Guide.
It looks like Oprah, but in reality it's only Oprah's head. The body belongs
to Ann-Margret. The composite was created without the permission of Oprah or
Ann-Margret. |
|
| •The question of what is real—whole issue of visual truth
is an important area of visual computing—intersection of technology ,
theory, philosophy, perception, etc. Not only in situations where someone
is intentionally trying to mislead you—but in many instances where a
computer-generated image can be misleading in ways that the producer of the
images in not even aware of. |
|
| This and others I
will show in a minute show an interesting interplay between image
interpretation based on perception (fooled by digital photo) and the actual organization of data
making up the image. (which we’re going to look at briefly next) |
