We reside in an age of fantastic technological advancements in the visual technology fields. Photo camera models renew themselves each and every year using the promise of more mega-pixels and latest features. Yet, whenever we contemplate it for a moment, the photo that comes out of your cameras usually has weaknesses and strengths that persist through every one of the successive appliances proceed through our hands.
Digital Cameras and in general all photographic cameras are, despite every one of the marketing buzz, still limited machines. By way of example, they register the world with sensors that can only capture half the tonal range which our eyes can perceive.
Imagine yourself a sunny day facing a lovely landscape. Below you, around the feet, you can see the rich lush green vegetation; above you, the bright blue skies. Even as we contemplate this scene, our eyes have the ability to perceive its richness, the details in the shadows and also the bright clouds above. The dynamic range our eyes can process, which goes from your darkest for the brightest areas, is sufficient contain most of the rich detail for the reason that scene.
Now bring your photo camera and snap an attempt from your position including the vegetation along with the sky. It feels right very telling. With respect to the parameters that either your camera or you choose, some detail with the scene will be gone from your result. Either elements of the vegetation will blend to black and lose all detail or elements of heaven will blend to white and lose all detail.
To conclude, the retina from the camera, its digital sensor, which captures the sunshine from the scene, just isn’t competent at dealing with a tonal range as huge as our eyes can. It may only capture the full detail in a smaller range which can be positioned at different levels of brightness by the camera itself or us. For that, inside a scene such as the one described above that has a huge contrast, it ends up capturing the detail only at the highlights and mid-tones, or mainly in the mid-tones, or mainly with the shadows and mid-tones. It cannot capture simultaneously the full detail from the scene from the darkest for the brightest areas.
That is of course a simplification associated with an scenario that we could describe in far more detail. But the conclusion remains the same. If we go through the final photo, can certainly that what we remember seeing with our eyes is not exactly what the photo shows. That richness of detail everywhere is finished. And this is one amongst the restrictions that Photo cameras share. We will pursue to describe many more related to color precision and other places that cameras just cannot cope with the depth and richness on the planet around us.
