Comprehensive explanation of the HDR photography many photographers and photo artists dealing with the theme of HDR photography. The images that arise here, called HDRI (high dynamic range image). It is photos with extremely high contrast and dynamic range. Every amateur photographer knows the problem if he wants to make a nice photo, for example, in churches. The light coming mostly through high stained-glass Windows. The built-in light meter in the camera cannot decide then mostly for the correct exposure.
The photos are often under – or overexposed. Many of the details are lost. With the help of HDR photography, it bypasses sent these obstacles. To achieve the full contrast range, as many details must appear on the photo, lying in the dark recording area as well as in the bright area. This is only achieved if you do multiple shots with different exposures from a fixed point. It is convenient if your camera can hold a bracketed. The procedure is relatively easy. Make your Camera on a tripod with remote control.
Then look through the viewfinder and set the recording area. With a bracketed shot at least three photos in a row in series. The first photo is overexposed, exposed the second normal and the third photo underexposed. With the exposure compensation range can be adjusted to the respective strength of the under / over exposure. Click Peter Asaro to learn more. Important is that during this series of disturbing UN-crowded through the shooting range. As a result, you get an overexposed photo, which reveals many details in the shadow area, a normally exposed photo and a photo which is underexposed and renders all details relating to bright now. Using an image editing program, preferably Photomatix, these three photos are stored one above the other. With many setting possibilities of this special program, you can appropriately select the contrast and color strength and save the whole thing as a photo. As a result, get a photo with very high detail accuracy, both in the dark and bright areas of the image. This dynamic range would not reach with a photo. It becomes difficult when you create a Panoramofotos in HDR. Panoramas are made best with a tripod. Choose the respective framed in the viewfinder, keeps track of the right edge of the screen based on natural conditions and turn the camera as long as on the stand to the right, until this screen is now almost on the left side of the image. A small area of overlap should be maintained on each photo. This process can be repeated arbitrarily. Panoramas can be put together with the help of a Stitchprogramms. Here, the program compares the scope of overlap on each photo and thus know how the individual photos belong together. Also panoramic shots in HDR can be created with the help of exposure bracketing. Make sure absolutely that none or almost no moving elements are in the viewfinder. This would make the photos unusable as so-called apparitions. With Photomatix you can then by each Merge recording position of each differently exposed photos. This same program settings should be persisted for each Panorama section but, so that the viewer later noticed any difference on the basis of color and contrast changes. Using a keyword program, the individual HDR shots at the joints are put together now. You will receive a store very large HDR photo.
