Affective computing is an important research area for developing an emotion recognition system. In such systems, stimuli for emotion elicitation are standard dynamic range (SDR) multimedia content. This study uses high dynamic range (HDR) multimedia content that effectively presents the scene’s inherent colors and high dynamic range of luminance as stimuli for emotion elicitation, and its impact on human emotional experience with different personality traits is explored. For this purpose, four low and high-valence multimedia clips in SDR and HDR versions were shown to sixty subjects. Their emotional experience was recorded on a valence-arousal plane, which is then statistically analyzed in terms of the type of content and human personality traits. The results of the t-test with a 95% confidence interval show that HDR multimedia content elicits better emotions than SDR multimedia content and can be effectively utilized in emotion recognition systems for better emotion elicitation.
