The high dynamic range images usually enable the photographer in recording a good range of those tonal details that a camera could ever capture in one picture. This usually opens up a new set of the lighting possibilities that one would have avoided before because of some technical reasons. The merge to the HDR feature of the Photoshop is accomplishing all of this by means of combining the bracketed exposure to one image that encompasses the detail of the whole series.
There would be no free lunch, but if you are trying to broaden its tonal range it would inevitably come to an expense of the decreased contrast to some other tones. To learn on how to use the software of the HDR could really help in making the most of the dynamic range that is under the tricky lighting even if it is still balancing the trade-off contrast. As the digital sensors had reached a higher resolution, and successively the smaller sizes of the pixel, the quality of the image does not benefit from the dynamic range.
This is usually apparent in the modern cameras that are compact that has more than 8 megapixels because these are more susceptible to the blown highlights and the shadow detail that is very noisy. Some scenes only contain a range of a great brightness that could be captured by the present digital cameras. Its bright side is that mostly of any camera could really capture a wide dynamic range and not only the single picture. Through the variations in the shutter speed, mostly of the digital cameras could change the amount of light that they would like to let in by 50,000 or more.
The dynamic range imaging that is very high is utilizing the characteristics by means of creating an image that is composed of many exposures. Use only the HDR if the distribution of the brightness of the scene could not be easily blended with the use of the GND filter. It is because the GND filter is extending the dynamic range at the same time maintaining the local contrast. Scenes that are suitable for the GND filter are those that has simple geometries for lighting like the linear blend that is from the darker land to the bright sky on landscape photography.
Those scenes that the brightness distribution did not easily blend with the use of the GND filter are a doorway scene. Photoshop is creating an HDR file with the use of the EXIF info that came from those bracketed images in order to determine the shutter speed, the aperture and the ISO settings. This is telling the Photoshop of the amount of light that had actually come from the image region. Since the light usually vary on the intensity, the Photoshop is creating an HDR Pictures Photography file with the use of the 32 bits in order to describe the color channel.
With the new tools, always be careful in not overdoing the use. You need to take an extra care if you are violating the original hierarchy of the image. HDR should be used only if necessary because best results could only be achieved if you had a good lighting.
