We are now living in an age of wonderful technological advancements from the visual technology fields. Photo camera models renew themselves each and every year together with the commitment of more mega-pixels and new features. But, if we contemplate it for just a moment, the photo which will come out of each of our digital camera models most times has strengths and weaknesses that persist through all of the successive appliances undergo our hands.

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

Imagine your self on a sunny day before a lovely landscape. Below you, around the feet, you can observe the rich lush green vegetation; above you, the intense blue skies. As we contemplate this scene, our eyes can perceive all of its richness, the important points in both the shadows as well as the bright clouds above. The dynamic range that the eyes can process, which matches through the darkest towards the brightest areas, is sufficient contain almost all of the rich detail in that scene.

Now take the photo camera and snap an attempt from your position including the vegetation and also the sky. It makes sense very telling. Based on the parameters that either the digital camera or else you choose, some detail from the scene will disappear through the result. Either aspects of the vegetation will blend to black and lose all detail or elements of the sky will blend to white and lose all detail.

To sum up, the retina in the camera, its digital sensor, which captures the sunlight from the scene, is not competent at dealing with a tonal range as big as our eyes can. It could only capture the full detail in a range that could be positioned at different levels of brightness by the camera itself or us. For that, in the scene such as the one described above that has a large contrast, it ends up capturing the detail limited to the highlights and mid-tones, or mainly at the mid-tones, or mainly in the shadows and mid-tones. It really cannot capture simultaneously the full detail with the scene in the darkest on the brightest areas.

This is naturally a simplification associated with an scenario that individuals could describe in a lot more detail. Though the conclusion continues to be same. When we look at the final photo, we understand that that which you remember seeing with this eyes isn’t what are the photo shows. That richness of detail everywhere is fully gone. Which is one amongst the restrictions that every Photo cameras share. We will go on to describe a great many others associated with color precision and other locations where cameras cannot manage the depth and richness worldwide around us.
