We presented a survey on High-dynamic-range imaging (HDRI or HDR) is a set of methods used in the imagingand photography to reproduce a superior dynamic range of luminosity than regular digital imaging or photographic methods can do. HDR images can denote a superior range of the luminance levels than can be attained using the extra 'classical' techniques. Images such as those holding many actual-world scenes, from same bright and direct sunlight to dangerous shade or very faint nebulae. It is the often succeeded in catching and then joining numerous dissimilar exposures of the similar subject matter. A Non-HDR cameras take a photograph with some limited amount of exposure range, as finally resulting in the damage of the detail in bright or dark parts. In this paper, we are studying about HDR image, generating of HDR image and also study about image fusion and methods of image fusioning.
