Technical study of high dynamic range Photograph
When the digital technology in the field of imaging photography and his world, people thought
it will be interesting to photographer and Sciences that this technique is just replacing raw film
traditional ones with Electronic.
At the beginning the digital photographic image had a lower quality than the traditional film, but the
acceleration in the evolution of digital technologies photographic image and graphic processors, as well
as offering the imaging process technologies themselves create a new situation of integrating artistic
vision and technical innovation.
The digital imaging technologies opened up many before photographers, and allowed them a
greater ability to control the tones recorded image, as well as the ability to control the highlight fine
details in each part of the image, rather than made available conventional techniques of film, and
chemical treatments for these raw materials, The most important of these techniques are known
idiomatically high dynamic extent of the photographic image, which is the subject of this research.
Through the above, we can say that the search problem is in the questions:
- What is the scientific and technical basis for producing photographic images with high dynamic
range?
- What are the methods of control in a high dynamic range photograph?
The research aims to clarify the methods to obtain the long high dynamic image
photographically, and how to control the amount of the fine details resulting image photographic
despite the different regions of lighting topics, so that the photographer can by these digital
technologies highlight aesthetic values they wish to achieve, and according to his artistic vision and his
abilities Creative.
To make this discussion dealt with the definition of high dynamic range technology image
photographic and the emergence of producing images with high dynamic range and its evolution, and
then a review of the programs produces images with high dynamic range HDR software:
( Program Photomatrix, Photoshop Element , Photoshop).
After that, the researcher introduced requirements to produce images Dynamic Range Higher,
patterns capture shooting Modes, and image file formats used to work with dynamic High Photo file
type, then accessories complementary used to get HDR good, and even explain properties to produce
images used to integrate the image of high dynamic range , And then modes generated images with
high dynamic range using Photoshop.
Then the researcher does two applications to produce the final image with a high dynamic
range, one of the Tahrir Square and the other in the same day of the National Democratic building
burning ,He then reviewed the results and recommendations.
