Aw, someone is upset. Photography can be good, but the ease with which an untrained person can capture an image of arguable artistic credibility means that the field is diluted to the point of most people being untalented and a very small number of people using the media in ways that are artistically relevant.
Why did the artist use photomedia for this work? Nothing about the work itself lends itself to the media. The guy realised he could make a mess and shoot it. Wow, thanks Jon... where would we be without this vital contribution to the field?
FWIW I have a degree in visual arts.... do you? You might rightfully be able to claim my 'literature' as untalented (though, believe it or not, I'm not exhibiting my BB comments in a gallery and having them blogged about), but you can't call my comments uninformed and uneducated... they're the exact opposite of that.
