Initial consumer HDR displays will operate on a peak brightness of about 500-1000 nits while in the coming years display peak brightness is expected to go well beyond 1000 nits. However, professionally graded HDR content can range from 1000 to 4000 nits. As with SDR content, we can expect HDR content to be available in variety of lighting styles such as low key, medium key and high key video. This raises concerns over tone-compatibility between HDR displays especially when adapting to various lighting styles. It is expected that dynamic range adaptation between HDR displays uses similar techniques as found with tone mapping and tone expansion operators. In this paper, we survey simple tone mapping methods for 4000 nits color-graded content for 1000 nits HDR displays. We also investigate tone expansion strategies when content graded in 1000 nits is displayed on 4000 nits monitors. We conclude that the best tone reproduction technique between HDR displays strongly depends on the lighting style of the content.
