Six Month Old Dry Cough Teething

What is the 'HDR (High Dynamic Range)

's HDR stands for High Dynamic Range, is a technique used in computer graphics and photography to allow the lighting calculations can be done in a larger space (just a high range) and can represent values \u200b\u200bof very high or very low lighting.

HDR techniques are based on the physical nature of light. To calculations using the same units of photometry, where, for example, the sun is assigned a brightness value millions of times greater than that of the personal computer monitor.

The HDR makes it possible to capture a scene and then having total control on the final image, for example, you can display the picture again, correcting or improving the outcome.

For photographers open up new possibilities, just look at a few small photos to see the great potential of HDR.
The management of this technique invented by Paul Debevec and Greg Ward from encoded file has leaned to the fore with the advent of Photshop CS2, which allowed to generate and manage files in HDR format of a series of multiple shots exposed in different ways.

then the emergence of programs such as the HDR Photmatix made closer to all the fashion has spread especially among amateurs. Achieve professional results, however, is not entirely straightforward because the HDR is amazing results but leaves behind few traces. Finally, the advent of the new generation of computer processing times more human than with 32-bit files to 16 and stretch out of proportion.

So if you want photos with unimaginable detail and tonal separation and lighting amazing we have to use HDR.

In this tutorial: explore the possibility that this photographic technique offers us understand what tools we need to achieve acceptable results we will see how to apply the technique to individual files.

For a discussion of this topic, I refer you to the site of Vittore Buzzi from which I took over the party.

Below is an example made Topaz Lab
