During last week's IVRPA conference in Las Vegas, I arranged an after hours photo tour at the Neon Musem. The museum runs 1 hour guided tours during the day and evening, but no tripods or monopods are allowed. About once a month they have a night shoot that allows tripods. Big thanks to the talented photographer eyetwist, who gave me the lowdown, and to Erin at the museum for the hospitality. We had 7 photographers and 2 videographers in our group, which maxed out the small museum space.
As we only had 1 hour in the boneyard, I shot my 360 panos at 4 shots around, using a Canon EOS 6D with the 8-15mm fisheye lens at 12mm. This sacrifices some resolution for speed, producing images that are just over 10,000x5,000 (50 megapixels). I shot a 3 image bracket at each camera position, with exposures of +/- 1.5 stops.
Many of the amazing old neon signs were lit with bright LED lighting that scrolls through different colors every few seconds. I knew this was going to make both shooting HDR and blending the panoramas a challenge. Surprisingly, Photomatix Fusion didn't have any problems blending the bracketed images, even though the color and intensity sometimes changed between exposures.
Next, I imported the images into PTGui Pro. Here's how the pano looked after stitching, but before blending across images.
I tested PTGui, Smartblend, and Photoshop, and the PTGUI blender did the best job feathering the different colored lighting. Adjusting the masking in PTGui helped fine tune the transition areas.
Once I was happy with the results, I used Pano2VR Pro to create the interactive panorama. This pano is my first test using the new HTML5 multiresolution feature. As time permits, I will add a few more panoramas from the Neon Museum and create a virtual tour.
