Abstract

High dynamic range (HDR) imaging was used to obtain a wide intensity map of a magnetized sheet plasma. A set of 12 low dynamic range (LDR) photography with various shutter speeds (1/200-1/2 s) was captured with an Olympus FE-19 digital camera. The LDR images were processed to recover color channel response functions of the camera needed to produce RGB radiance maps. The HDR image was finally generated from the combined radiance maps via linear tone mapping. By comparison of histograms, the HDR image uses the whole range of intensity values compared to the underexposed and overexposed LDR images.
