High dynamic range imaging has become very popular over the years in the field of computer graphics and games. The process of tone reproduction compresses the dynamic range of brightness in a scene to the lower range of display devices, thus making it an essential process in the graphics rendering pipeline. Various tone mapping operators have been tested for static viewing conditions. However, perceptual and temporal adaptation may vary for immersive viewing in a Virtual Reality environment. This thesis implements Ward et al. model (1994), Ward et al. model, Histogram Adjustment (1997) and Irawan, Ferwerda and Marschner model (2005) for static and immersive inputs. Faculty and students from the college took part in a personal survey to rate the tone mapped results based on their level of resemblance to real-life outdoor environments as well as the level of visibility in the lighter and darker regions. The proposed hypothesis states that immersion produces a measurable effect on our preference for a suitable tone reproduction model. This hypothesis is tested with the help of null hypothesis testing methods and some regression analysis on the data gathered from the survey.
