I was referring to photojournalism specifically.
And yes, many product shots are already CGI such as those car advertisements where the car is in an unlikely place such as a boxing ring.
I know, hence why I mentioned the Presidential Inauguration. But not necessarily that it would do away with photojournalism, but photojournalism may be tough to believe eventually.
Photoshop has already made that a reality. But it would be hard for a newspaper to CGI an inauguration beforehand or during considering that news nowadays is more about the scoop than the story itself.
I don't think that at this time 3D models can be create quickly enough to satisfy the instant gratification culture. Since wire service are now online and he Associated Press is as well, newspapers can purchase photos and news at a bargain.
It would be both unethical and impractical.
