Split Screen is the title of Annie MacDonell's photography piece posted at her website and also exhibited (posted) at the online at site Either/And on August 25, 2013.
From Annie MacDonell's program notes for Split Screen:
The images in...[Split Screen] are scans of found 35mm slides. I came across a box of them next to the trash a few months ago. They were unlabeled, undated, and unsourced. I’ve put together a selection of 15, which now form a slideshow you can click through on your computer monitor. Maybe you will recognize some of the images. Others you may not recognize specifically, but you will certainly be familiar with their sources – art monographs, fashion magazines, notebooks and textbooks, technical manuals.The gallery's website describes MacDonell thus:
Annie MacDonell is a Toronto-based visual artist working with photography, film, sculpture, installation. Her recent work draws attention to how still and moving images are staged in the spaces of gallery and cinema, creating multi-layered, uncanny and formally elegant meditations on the act of looking. Annie MacDonell received a BFA from Ryerson University’s School of Image Arts in 2000, followed by graduate studies at Le Fresnoy, Studio National des Arts Contemporains, in Tourcoing, France. Recent solo shows include the Art Gallery of Windsor, the Art Gallery of Ontario and Mercer Union Gallery, in Toronto. She has participated in group exhibitions at The Power Plant, Toronto, Mulherin & Pollard, New York, Le Grand Palais, Paris and the 2012 Daegu Photo Biennale, in South Korea. In 2012 she was long-listed for the Sobey Art Award and short-listed for the Grange Prize. She teaches in the photography department at Ryerson University and her work is represented by Katharine Mulherin Contemporary Art.***Disclosure: MacDonell was a classmate of mine while I was studying Film, Photography and New Media (New Media is now re-named Integrated Digital) at Ryerson University's School of Image Arts. I remember her as perennially perplexed, and even angry. Her projects were labours of, well labour, of precisely this "appropriated" art of which she is now an expert. She would at one time follow my progress with avid, and strange, curiosity, and for reason: I finished my two-year "term" with multiple exhibitions: Film, video and photography pieces. All my work was later exhibited at external venues.***
Don't be fooled by the sophisticated art language MacDonell uses to describe her Split Screen project. Artists are at such want for "topics" that they cling on to any subject which might give them a potential project.
The underlying theme of MacDonell's work, if MacDonell is even aware of it, is simply: destruction.
"...the spine’s interruption of the image reminds us of where they came from in the first place..." writes MacDonell.
And she continues:
The visibility of the spine is what attracts me to them. It marks one of the many transformations these images have undergone since they were produced by the original artist.There are a variety of images in Split Screen, all with "naturally" occurring splits: a hospital operation table, a messy room perhaps in a house about to be vacated, a magazine shot of crotches (male? female?), an orgy of legs, the Sistine Chapel ceiling, and the sculptured head of Christ from Michelangelo's Pieta.
[...]
Each one contains an interruption of the image by the spine of the book in which it originally appeared
Cleverly, MacDonell gives us no background on any of the images. She has a bigger purpose than juxtaposing interesting photographic shots.
The sculptured head seems the least aggressive of her choices. There is a serenity around this head, and the sculptural work is of high quality. And here, MacDonell treads very carefully. She has removed the head from its context and its significance, and it appears to be simply the head of a man sleeping.
MacDonell's "head" is all the more disconcerting because it is at a different angle from which we would be accustomed to seeing it. The photograph was taken from the top rather than the side, thus exposing to us Christ's full face. And it is also flipped to its mirror image.

The Pieta in St. Peter’s Basilica
What was a deeply religious work, the head of the dead Christ on his mother's knees after he was taken down from the crucifix, becomes the head of a man.
But why the split screen?
MacDonell is subtly and carefully "dismantling" Jesus. Removing, first his Godliness by presenting him as a mere man, then his intellect, his personality by splitting him, his head, apart. A form of decapitation, worse perhaps than the crucifix. At least after the crucifix, Jesus' body was left intact. But with MacDonell's rendition even Jesus' mind, his Godly intellect, is removed.
Despite its apparent tranquility, this is the most aggressive of the works played on Split Screen, where MacDonell attempts to kill off God permanently: body, mind and spirit.
