Blog Exercise: Week 3

Feature Channels and Visual Search

Wonder Bread logo

Obama photograph

With feature channel processing, in the both the Wonder Bread logo and the photograph of Obama, the use of color and shape make the dominant message or meaning of the image stand out. In the logo, the yellow circle stands out because its hue or brightness—this may be communicating that the yellow circle is of significance to the product message or of the branding. In the photograph, a photography editor for a news organization may have chosen this photo to illustrate an element of a story on the subject (Obama). The shape and orientation of the illuminated cross in the center of the photo is clearly meant to be the dominant focus. The photograph communicates to the viewer that this object might carry more significance than the subject (person) in the left, lower part of the photograph.
