Today, you can often see people with cameras. They are found almost everywhere and constantly take pictures of something. But not only a large number of photographers are surprised by this area of activity. The modern art of photography is also striking in those opportunities that are available to almost everyone who picks up the necessary device.
One of these features is taking pictures with a wider dynamic range (HDR). What is HDR? This function is the creation of photographs that have an extended range of tones that go beyond the limits achieved by a single exposure.
Some digital cameras have this feature built-in. In this case, photographs need to be taken several pieces one after another. After this, the photos are combined in the device into a single photo, which carries a large number of shades and tones. The number of such HDR photos will depend primarily on the particular model of camera. It should also be noted that various levels of photo management are available to such devices. With the help of these levels, it is possible to obtain unique photo images that will correspond to certain preferences.
Now that the question of what HDR is has become clear, you should deal with photo editing. Two methods can be used for this, which involve the use of a special program.
The first method is based on the inclusion of creating multiple exposures of an object that was obtained from one shooting point. Editing in this case is necessary in order to combine several photos into one image.
The second method involves the use of one photograph, which is divided into several elements during the editing process. The dynamic range in this case is configured for each element individually. And at the end, the elements are combined into one image.
When creating an HDR photo from one shot, the functionality is limited, since the tone range is not quite flexible, as is the case with multi-expo. The main advantage of this method is the fact that you can create HDR for a moving object.
For further processing, you should use the controls that will allow you to create an exposure that suits the preferences of users. These elements directly depend on what software is used. The question of which utility is best used is no less common than the question: what is HDR? Editors from Adobe, namely Photoshop, are popular. It is desirable that the version of this tool is not lower than CS2. Also currently popular is a program like Photomatrix.
On this, the main points that relate to the question of what HDR is can be considered considered. If necessary, refer to specialized portals for more detailed information; you can find a detailed description of all the issues that interest you.
