Good afternoon,

I?m very much interested in using High Dynamic Range Imaging (HDRI) for
recording illuminance values in office buildings as part of Post Occupancy
Study. I am using Photosphere software to generate the HDR images, but I am
not sure how to convert the luminance values/images to illuminance values.

Any advice would be appreciated.

Many thanks
