The sample images were captured on Kodak 5245 motion picture negative 
film, using a Canon A1 still camera.  The negatives were scanned using
ILM's custom-built film scanner.  Each image is a composite of three
to five separate exposures; the difference between successive exposures 
was two f-stops.  Registration and compositing were done with ILM's
in-house software.

This method is not necessarily the most convenient way to capture
high dynamic-range images (unless you happen to work at ILM), but 
if you have a digital camera that lets you get at raw unprocessed 
pixel data from the image sensor, you can produce high-quality images 
by combining multiple exposures, using software such as Greg Ward's 
Photosphere or Paul Debevec's HDRShop.
