<div>Hi there,</div><div><br></div><div>I ran into this paper which gives a very complete overview of different techniques for environmental lighting capturing, comparisons, ... for example it compares to use of mirror balls, fisheye stitched images or professional all-in-one equipments.</div>
<div><br></div><span style="border-collapse:collapse;color:rgb(34,34,34);font-family:arial, sans-serif;font-size:13px;"><a rel="nofollow" target="_blank" href="http://www.hdrlabs.com/tutorials/downloads_files/HDRI%20for%20CGI.pdf" style="color:rgb(17,85,204);">http://www.hdrlabs.com/tutorials/downloads_files/HDRI%20for%20CGI.pdf</a></span><div>
<br></div><div>I thought that could be of use for Mango team.</div><div><br></div><div><br></div><div>* note: I'm exploring recently building spherical panoramas for lighting AND for background plate. That is a bit different from Mango that needs IBL (Image Based Lighting) but not necessarily the background part of it. This paper may still inspire some ideas though.</div>
<div><br></div><div>* note2: a recent capture we took here with 6 (side with zenith) + 4 photos (nadir) . We are quite happy with the LDR (and it's damned fast as a workflow), but the HDR is yet to be mastered (and Hugin is not working well for this):</div>
