The Process of Digital Photo Retouching

We live in an age of fantastic technological advancements from the visual technology fields. Photo camera models renew themselves annually using the promise of more mega-pixels and latest features. And yet, whenever we contemplate it as it were, the photo which comes out of each of our old digital cameras most times has strengths and weaknesses that persist through all the successive models that proceed through our hands.

Cameras plus general all photographic cameras are, despite all of the marketing buzz, still restricted machines. For instance, they register our world with sensors that will only capture a small fraction of the tonal range our eyes can perceive.

Imagine yourself on a sunny day looking at a lovely landscape. Below you, around the feet, you can view the rich lush green vegetation; above you, the intense blue skies. Once we contemplate this scene, our eyes are able to perceive all its richness, information in the shadows as well as the bright clouds above. The dynamic range that the eyes can process, which fits from your darkest for the brightest areas, is enough to contain almost all of the rich detail in this scene.

Now take your photo camera and snap a trial out of your position including both vegetation and also the sky. It feels right very telling. With regards to the parameters that either the digital camera or perhaps you choose, some detail in the scene will be gone through the result. Either elements of the vegetation will blend to black and lose all detail or elements of the sun will blend to white and lose all detail.

In conclusion, the retina in the camera, its digital sensor, which captures the sunlight from the scene, just isn't competent at coping with tonal range as large as our eyes can. It can only capture the entire detail in a smaller range that may be positioned at different degrees of brightness from the camera itself or us. For that, within a scene like the one described above with a very large 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 simply cannot capture simultaneously the complete detail from the scene from your darkest for the brightest areas.

That is obviously a simplification of your scenario we could describe in a lot more detail. Nevertheless the conclusion is still the same. If we go through the final photo, can certainly that that which you remember seeing with this eyes is just not just what the photo shows. That richness of detail everywhere is finished. Which is one of the limitations that all Photo cameras share. We might pursue to describe many more linked to color precision as well as other locations where cameras simply cannot cope with the depth and richness of the world around us.
