HDRI Studio Tests

These are three HDRI tests I took earlier this evening with a garden "gazing sphere" I bought off amazon and a SLR camera which I could only borrow for a few hours. So what is it I'm trying to achieve? By creating a set of High Dynamic Range Images (HDRI's) for the sites in Edinburgh I can then create panoramas of the lighting of the sites which can be used in Maya using Mental Ray's Image Based Lighting (IBL) effect. This means that the images are what is driving the light and reflections of the scene making any 3D objects placed within it integrate better with the live action plate. Regardless of the outcome which seems too dark at present, it was very fun and I look forward to going through to Waverley in the next week once I've perfected the technique to get some final ones.

So here we have the studio corridor, the studio itself and the external studio roof. The first set of circular image are the Photoshop HDR's used by combining 5 photographs of different levels of darkness together, the panorama is the two images merged in Nuke and the final is a 3D red sphere in Maya where I have tried to used the HDRI's as Image Based Lighting. Long way to go but a start.
