Photo(s) of the Day:Juliet Retouch by Lorena Sturlese

While the photos are Lorena Sturlese’s, I found them via the Dartmouth Photo-shop Revealing Tool (I dislike “photoshop/photo-shop” being used as a verb… but at this point it’s like calling petroleum jelly “vaseline”). From a summary of the Project available on Slate:

“The Dartmouth students and their professor developed a tool and system (described on Mashable) to create a “Photoshop rating” for any given image, so that a heavily edited image would get a five, while something untouched would be a zero. Can you imagine a world in which every advertising image or magazine fashion shoot carried, in effect, a warning level, with a “five” standing for the concept “no one really looks like this?” “

Photo of the Day: Close Relative? by Mac Haas

This is a photograph of the right paw print of a Bioko drill (Mandrillus leucophaeus poensis) taken during primate census at the Gran Caldera, Bioko Island, Equatorial Guinea.

Bushmeat hunting for drills and their consequent evasion of humans means the endangered, baboon-like drills are seldom seen in the wild, and even more rarely photographed. Instead, ephemeral evidence such as this damp, hand-like paw print – left just a minute or two before it was photographed – is the only trace of a near encounter between photographer and primate. The photograph begs the question “who is watching whom?”
