Tea Vui Huang's Instant EXR mobile phone application lets you create a High Dynamic Range Image (HDRI) in the form of ILM's (Industrial Light & Magic, a division of Lucas Digital Ltd. LLC) OpenEXR latitude-longitude environment map from a sequence of mobile phone photos.
The process takes about 20 seconds for each 1024x512 EXR. The OpenEXR files it creates can be imported directly into SOFTIMAGE|XSI & Autodesk Maya to render photo-realistic 3D scenes and animation. The Instant EXR generated environment maps can be used with Final Gather or Global Illumination to perform Image-Based Lighting (IBL). The fully-functional application and sample EXR can be downloaded from the website above.
