The image above is a finished and retouched photograph from a recent shoot at an MRI lab. It is a great example of how the work done on location and during post-production complement each other. Each is a piece of the larger puzzle and good planning on location means that the puzzle will go together correctly.
Greg set up the shot knowing that one frame could not create the image he wanted: the brightness of the light in the room where the MRI machine sits is much higher than inside the control booth, the computer displays would be completely blown-out highlights, etc. On shoot he captured many puzzle pieces like separate exposures for the two rooms, and exposures for the computer screens.
On the left is the a small portion of the image as it was straight out of the camera, on the right we can see the same portion of the image after all the digital magic has happened. Click on the picture to view a larger version.
