With the developments in Image acquisition techniques, there is an increasing interest towards High Dynamic Range (HDR) images where the number of intensity levels ranges between 2 to 10,000. With these many intensity levels, an accurate representation of luminance variations is absolutely possible. But, because the standard display devices are devised to display Low Dynamic Range (LDR) images, there is a need to convert HDR image to LDR image without losing important image structures in HDR images. In the literature, a number of techniques are proposed to get tone mapped image from HDR images. In this paper, an attempt has been made to analyze four TMOs, i.e., Linear Mode, Gamma Correction, Reinhard and Reinhard with color correction. A subjective analysis tells us that the Reinhard with color correction has produced better results. In this paper, two new tone mapping operators are proposed.

HDR, LDR, Tone mapping, Gamma Correction.
