The Art of Digital Photo Retouching

We reside in a time of wonderful technological advancements within the visual technology fields. Photo camera models renew themselves each and every year together with the promise of more mega-pixels and new features. Yet, whenever we consider it for a moment, the photo links away from each of our digital camera models most times has good and bad points that persist through each of the successive mixers proceed through our hands.

Cameras and in general all photographic cameras are, despite all of the marketing buzz, still not a lot of machines. For example, they register our universe with sensors that could only capture a part of the tonal range which our eyes can perceive.


Imagine your self on a sunny day facing an attractive landscape. Below you, around your feet, you can view the rich lush green vegetation; above you, the bright blue skies. Once we contemplate this scene, our eyes can easily perceive it's richness, the facts in both the shadows as well as the bright clouds above. The dynamic range which our eyes can process, which fits from the darkest to the brightest areas, is enough to contain a lot of the rich detail in this scene.

Now take the photo camera and snap a go from your position including both vegetation and also the sky. It's wise very telling. Based on the parameters that either you otherwise you choose, some detail in the scene will disappear in the result. Either areas of the vegetation will blend to black and lose all detail or areas of the sun will blend to white and lose all detail.

To conclude, the retina from the camera, its digital sensor, which captures the sunlight of the scene, isn't able to dealing with a tonal range as big as our eyes can. It may only capture the full detail in a small range that can be positioned at different degrees of brightness through the camera itself or us. Because of this, in the scene such as the one described above with a huge contrast, it ends up capturing the detail limited to the highlights and mid-tones, or mainly in the mid-tones, or mainly in the shadows and mid-tones. It really cannot capture simultaneously the full detail in the scene through the darkest for the brightest areas.

This can be of course a simplification associated with an scenario that we could describe in considerably more detail. Though the conclusion is still the same. Once we go through the final photo, we understand that what we should remember seeing with your eyes is just not what the photo shows. That richness of detail everywhere is gone. And this is one amongst the constraints that every Photo cameras share. We might will continue to describe a great many others linked to color precision and also other areas where cameras just cannot deal with the depth and richness around the globe around us.
