There are always debates about what is appropriate post-processing for a photograph. Should a color be enhanced? Is it okay to remove an object? Is it okay change the sky? And heck, some "purists" don't even think cropping should be allowed. Sometimes I think there are some photographers that won't even straighten a horizon.
Of course, we all stand at a slightly different place on the spectrum of post-processing – from strict "out of the camera" literalists to those folks who think photography didn't exist before Photoshop.
But I was recently thinking (100º days in Houston tend to keep one inside and idle) about the verisimilitude of photographs that are the result of the photographic technique rather than the post-processing. What piqued my little brain cells was yet one more article on long-exposure photos of water.
Consider the following photo techniques:
- Long Exposure - Many folks like long-exposure shots of moving water, a technique which gives the water a "silky smooth" appearance.
- Strong Bokeh - With a wide-open lens put the background so far out of focus it is but a mottled wall of color.
- Panorama - Panos are fun and give us a much broader perspective than our eyes naturally do.
- Bracketing - Bracketing lets us get rid of unwanted shadows and potentially blown-out highlights.
- Focus Stacking - Get all parts of the image as sharp as possible by taking 3 or 4 shots at different focus points.
Each of these photographic techniques changes what the eye sees. In reality, babbling brooks are not almost milky white and silky smooth. Our eyes do not naturally put the background into a creamy texture. Light is what it is, and our sight doesn't adjust to even out the light and shadows when we look at things. Nor do we see everything in focus or in wide panoramic scope.
One could argue that only the first two, Long Exposure and Strong Bokeh, are "out-of-camera" techniques and the others are the result of post-processing. But to my mind the initial images were taken with the purpose and intent of being manipulated and thus should be considered as out-of-camera processes.
So is manipulation in the camera any more legitimate than post-camera? Which is more authentic: a) the smooth waterfall with a telephone pole, or b) the non-smooth waterfall with no telephone pole.
I make no judgments here, I simply pose the question.
