The Process Of Digital Photo Retouching

August 9, 2018

We are in a time of wonderful technological advancements from the visual technology fields. Photo camera models renew themselves each year using the commitment of more mega-pixels and additional features. And yet, if we consider it for a moment, the photo that comes beyond your video cameras normally has weaknesses and strengths that persist through all the successive appliances undergo our hands.

Cameras as well as in general all photographic cameras are, despite each of the marketing buzz, still not a lot of machines. For instance, they register the world with sensors that could only capture a fraction of the tonal range that our eyes can perceive.



Imagine your self on a sunny day looking at a good looking landscape. Below you, around the feet, you can view the rich lush green vegetation; above you, the bright blue skies. Even as we contemplate this scene, our eyes have the ability to perceive all its richness, the details both in the shadows along with the bright clouds above. The dynamic range that our eyes can process, which works from your darkest to the brightest areas, is sufficient contain the majority of the rich detail because scene.

Now take the photo camera and snap a trial from a position including both vegetation and the sky. It feels right very telling. Based on the parameters that either the digital camera or perhaps you choose, some detail in the scene will be gone through the result. Either parts of the vegetation will blend to black and lose all detail or parts of heaven will blend to white and lose all detail.

In conclusion, the retina with the camera, its digital sensor, which captures the lighting in the scene, is just not effective at handling a tonal range the size of our eyes can. It may only capture the complete detail in a smaller range that could be positioned at different levels of brightness with the camera itself or us. Because of this, in the scene like the one described above with a huge contrast, it winds up capturing the detail only at the highlights and mid-tones, or mainly with the mid-tones, or mainly at the shadows and mid-tones. It cannot capture simultaneously the full detail with the scene in the darkest on the brightest areas.

This really is of course a simplification of the scenario we could describe in much more detail. But the conclusion continues to be same. Whenever we consider the final photo, we understand that might know about remember seeing with your eyes is not just what the photo shows. That richness of detail everywhere has disappeared. Which is one amongst the restrictions that most Photo cameras share. We will will continue to describe numerous others associated with color precision as well as other areas where cameras cannot handle the depth and richness around the globe around us.
