...if we are now living in a world where nothing matters but the final print, then a lot of computer-generated art should also be called 'photography', because there is practically no way to distinguish it from a 'real' photograph.
You say “should” as if this isn’t already the case. Over time, it has become accepted that a photograph is simply an image created by a camera - how or what happens to it is of no consequence.
Accepted by whom you may ask. Most people: Chris C lists a few. When the meaning of something is established (acknowledging that meaning evolves over time), it’s sensible to accept this. If I decide my own definitions, communication fails! Surely you’d agree that refusing the modern meaning of, say, “meat” would be foolish: originally it meant food in general, not flesh.
Returning to photography and adding another example photographer, consider Gursky. Gursky is well known for digitally manipulating images taken with a camera, often changing their appearance dramatically and creating one image from several. Yet he’s considered one of the most important living
photographers and his
photographs are owned by major museums such as MoMA in the US and The Tate in the UK, and I’ve just seen a massive exhibition in London’s prestigious Hayward Gallery of this “acclaimed German photographer” (as the gallery labels him).
In fact, Gursky’s photographs are considered so important to contemporary art that one became the most expensive ever sold at $4.5 million. That was “Rhine II” where all distracting objects such as buildings were Photoshopped out, to give a deliberate bland, banal appearance:
So, we need to go with the flow: photography today includes digital images and their manipulation, as well as film images. What folk are grumbling at is your attempt to define photography for everyone.
How you
personally make photographs is a different matter. If you only use film and make darkroom prints, and have no interest in digital photography, that’s fine. I use both film and digital, and my line in the sand is that I refuse to alter reality by adding or removing a feature that would be impossible in real life, so I’ll tidy up by cloning out, say, an annoying piece of trash that I couldn’t reach, but I won’t change a sky, delete a tree or move a lamp post.
The Heath Ledger image you posted involves far too much digital manipulation to interest me in working similarly and has moved too far from reality for my taste - but it is still photography, and I have absolutely no problem thinking of it as a photograph even though it’s an entirely new image collaged out of other photographs. As we all know, photographs are all fictions anyway and never depict the truth, with photographers showing you only what they want you to see...
