aether:
In that vein, here’s a suggestion of my own. Keep in mind that your ideas and suggestions might be used later to deceive someone.
I call that art. ;o) Actually, I occasionally fake things when paid or when my own work is outstanding modulo a few problems. The only place I worry about accuracy is when doing science or journalism. Otherwise, I just call my work photo illustration and skip all the issues.
And from a scientific perspective, I think I could craft an image in front of a jury that would be realistic beyond a reasonable doubt.
If, in spite of this, you still decide to contribute your expertise to the discussion, I have no objection.
In truth, I was actually looking at this suggestion as a way of checking for the quality of a manipulated image. Little things like this while not really visible (a small deviations in the signal), it is potentially something that could crop up in a billboard due to deviations in print runs for the different panels. Albeit, I have never been published in such a large format.
And in the end, unless it is a minor flaw in an otherwise great image or a rare scene, most manipulation is a waste of time as reshooting can be a lot faster. But when you do manipulate images (beyond mere color, contrast, and sharpness) it is nice to do it well.
The basics:
– Similar noise characteristics for all image elements. This can vary as images shift from focus to defocus (blurred).
– Similar lighting. Albeit, the use of flash in photography can make the lighting unreal in an unmanipulated image.
– Proper scale. Think shots with the full moon faked in.
– Similar color temperature. Again, the use of flash can create deviations in this. But dragging the shutter can somewhat ameliorate this in camera.
– Appropriate depth of field (DoF) that mimics the camera lens.
One could go on, but in the end it comes down to telling story (illustration) versus showing the reality (which the camera does not capture in truth). After all, the camera never lies, but it often deceives.
As for Mike C., I enjoy his play. But then, I can also admit 10 years ago he would have made me very angry.
enjoy,
Sean
