The Beauty of Digital Photo Retouching

We are in an age of amazing technological advancements within the visual technology fields. Photo camera models renew themselves each and every year with all the promise of more mega-pixels and new features. Yet, when we think it over as it were, the photo that comes out of each of our cameras many times has good and bad points that persist through all the successive mixers proceed through our hands.

Digital camera models and in general all photographic cameras are, despite every one of the marketing buzz, still restricted machines. For instance, they register the world with sensors that can only capture a small fraction of the tonal range which our eyes can perceive.



Imagine yourself a sunny day before a beautiful landscape. Below you, around feet, you will see the rich lush green vegetation; above you, the brilliant blue skies. Even as we contemplate this scene, our eyes are able to perceive its richness, the facts in both the shadows and also the bright clouds above. The dynamic range which our eyes can process, which matches in the darkest on the brightest areas, is sufficient to contain the majority of the rich detail because scene.

Now take the photo camera and snap a shot from the position including both the vegetation as well as the sky. It's wise very telling. Based on the parameters that either you or you choose, some detail with the scene will be gone through the result. Either elements of the vegetation will blend to black and lose all detail or areas of the sky will blend to white and lose all detail.

In conclusion, the retina in the camera, its digital sensor, which captures the light from the scene, is not able to handling a tonal range as large as our eyes can. It could only capture the full detail in a range that may be positioned at different levels of brightness through the camera itself or us. Because of this, within a scene like the one described above which has a huge contrast, it ultimately ends up capturing the detail only at the highlights and mid-tones, or mainly on the mid-tones, or mainly in the shadows and mid-tones. It really cannot capture simultaneously the total detail in the scene in the darkest on the brightest areas.

This can be naturally a simplification associated with an scenario that people could describe in much more detail. Though the conclusion remains the same. If we look at the final photo, we understand that what we should remember seeing with the eyes just isn't what are the photo shows. That richness of detail everywhere is fully gone. And this is just one of the constraints that Photo cameras share. We're able to will continue to describe many more in connection with color precision and other places that cameras cannot cope with the depth and richness of the world around us.
