Salam...hari ni nak bercakap pasal high dynamic range (HDR) ..ramai orang dah tau psl HDR ni..sy cuma nak share je apa yang patut..mcm2 cara utk kita gunakan teknik ni..ada yang guna untuk org, pemandangan dan sebagainya. So, ikut citarasa..tapi kena la belajar cara2 ni ye..sy pun masih belajar... ..ni berkenanaan HDR kat wikipedia " is a set of techniques that allow a greater dynamic range ofluminance between the lightest and darkest areas of an image than current standard digital imaging techniques or photographic methods. This wide dynamic range allows HDR images to more accurately represent the range of intensity levels found in real scenes, ranging from direct sunlight to faint starlight.[1]

The two main sources of HDR imagery are computer renderings and merging of multiple photographs, the latter of which in turn are individually referred to as low-dynamic-range (LDR)[2] or standard-dynamic-range (SDR)[3] photographs.
Tone-mapping techniques, which reduce overall contrast to facilitate display of HDR images on devices with lower dynamic range, can be applied to produce images with preserved or exaggerated local contrast for artistic effect. "

selamat berHDR ..Peace =)
