$6$ High dynamic range $($HDR$)$ imaging is a new methodology within image

capture $($formation$)$ whereby the image is digitized with a much greater range of quantization levels $($Section $2\mathrm{.}3\mathrm{.}2\mathrm{.}1)$ between the minimum and maximum colour levels. Matlab

supports HDR imaging through the use of the hdrread$()$function$.$ Use this function to load

the Matlab example HDR image office.hdr and convert it to a conventional RGB colour

representation using the Matlab tonemap$()$ function for viewing $($with imshow$()).$ Use the

Matlab getrangefromclass$()$ function and imtool$()$ to explore the value ranges of these two

versions of the HDR image.
