The Application provides a large collection of Nature Wallpapers in Original Quality.High-dynamic-range imaging (HDRI or HDR) is a set of techniques used in imaging and photography to reproduce a greater dynamic range of luminosity than standard digital imaging or photographic techniques can do. The aim is to present the human eye with a similar range of luminance as that which, through the visual system, is familiar in everyday life. The human eye, through adaptation of the iris (and other methods) adjusts constantly to the huge dynamic changes ubiquitous in our environment. The brain continuously interprets this information so that most of us can see in a wide range of light conditions. Most cameras, on the other hand, cannot.HDR images can represent a greater range of luminance levels than can be achieved using more 'traditional' methods, such as many real-world scenes containing very bright, direct sunlight to extreme shade, or very faint nebulae. This is often achieved by capturing and then combining several different smaller range exposures of the same subject matter.[1][2][3][4] Non-HDR cameras take photographs with a limited exposure range, resulting in the loss of detail in bright or dark areas.The two primary types of HDR images are computer renderings and images resulting from merging multiple low-dynamic-range (LDR)[5] or standard-dynamic-range (SDR)[6] photographs. HDR images can also be acquired using special image sensors, like an oversampled binary image sensor.Due to the limitations of printing and display contrast, acquiring an HDR image is only half the story; one must also develop methods of observing the results. The method of rendering an HDR image to a standard monitor or printing device is called tone mapping. This method reduces the overall contrast of an HDR image to facilitate display on devices or printouts with lower dynamic range, and can be applied to produce images with preserved or exaggerated local contrast for artistic effectPremium Nature HDR Wallpapers Features :You can share Nature Unique images using, Skype, Facebook, Twitter and also Premium Nature HDR images can be shared using Bluetooth or Messaging or Outlook you can also share these stunning images with Picasa, Gmail or Google plus or share Nature Wallpapers with friends via Email.All pictures and images can be saved to photo image gallery Set Nature Wallpapers as Home page WallpaperUnlimited Access and Download .Please Don't Forget 5 STAR for this Unique extraordinary collection of HDR images .Beauty is the gift from god .thank you For your Download .
