A Gigapixel Portrait

When I first started this project it was to create a 360 degree panorama of an art installation at the Hillyer Art Space in Washington, DC. The work, Ass Against the Wall is the work of artist Martha Jackson Jarvis. The piece was inspired by her trip earlier that year to Tajikistan, a mountainous landlocked country in Central Asia, as an Art & Cultural Ambassador.  This was also the first time I use my Gigapan EPIC for an assignment. The original idea was to create a 360 degree pano for a QuickTime VR movie. However the final image/movie was huge! Even when I reduced the pixel count by 50% it was still pretty big, but it wouldn’t choke a user’s system. This is what I came up with. Click & drag inside the frame to view the movie panorama.

 

The thing about 360 panos is that they’re 360 degrees! So as the Gigapan did it’s thing we were in the final images. I wasn’t sure if it had finished, so when I leaned forward to check its progress, my movement was recorded. One thing that I did discover was that Martha was watching the camera’s movement with great interest. So much so that the camera captured her as if posing for a portrait. It looked pretty good, so I now thought of the image as an environmental portrait. We decided to make a poster for her artist talk at the gallery.

Ass Against the Wall Exhibit Poster

Well neither the QTVR movie or the poster really show the detail of this gigapixel portrait. Even the poster had to be scaled down so it could be printed on a 36 inch by 17 in sheet of paper. After I had submitted the landscapes mentioned in my previous post, Revisiting the Gigapan, I decided to upload the original 360 panorama (cropping me out!) to show it in its full glory, so to speak. Interesting thing about this “final” image is that when I was processing it, I still cut it back by 50%, so it’s still not the true full gigapixel image. Use a navigation tool to pan & zoom through the image below. You can also use your mouse wheel as well as click & drag to pan through the pano.

A Quick on Location Shoot

Late afternoon, Wednesday, I did a quick and dirty location photo shoot of a piece of art for my friend Martha Jackson Jarvis. The shoot took place at Prince George’s African American Museum & Cultural Center, in Brentwood, MD. Martha will be in an exhibit, Resonant Forms, with artist Frank Smith, and Alonzo Davis.  OK. I was at the gallery to photograph a piece for Martha titled, Scarecrow. The reason why this was to be quick & dirty was that by the time Martha & I got to the gallery about quarter of an inch of slush from freezing rain was on on the ground. By the time I had set up my lights, about 20 minutes later, the freezing rain had turned to heavily falling snow. With about an inch of snow on the ground and an early rush hour, we all wanted to hurry up and get out of there. DC doesn’t do snow very well!

 The setup was pretty straight forward. Two Calumet Travelite 750 strobes. One with a small Chimera lightbox as the main light, and another Travelite with a 24 inch Calumet umbrella, as the fill. Because of the sudden state of urgency, along with Alec Simpson, director of the Art Exchange, & his staff wanting to get out of there, I didn’t have a lot of time to finesse the lighting. So after I got things up, and Martha was OK with the basics, I started shooting.  

When I was shooting this shot I was thinking of how I would be doing the re-touch in Photoshop. When doing this you don’t want to be sloppy.or the retouch can go horribly wrong. This shot is for the exhibition catalog and other PR for Martha and the exhibit. So I want it to be very tight for publication. So when I got back in an choosing the best exposed RAW file, I first brought the image into Adobe Camera Raw. Here I did the basic exposure & color cleanup adjustments before exporting it into Photoshop. Next, I use Nik Define 2.0 to quickly reduce any luminous noise. I shot at ISO 200 so there really wasn’t much, but Define cleaned it up. After Define I used the Stamp tool to get rid of pipes and light fixtures that where in the way. I actually cropped the image first to minimize this work. Next there was some tonal enhancement to accentuate the lighting that was already present in the shot. This help the over all contrast. Finally I added a touch of drama and place with a burn & dodge hand painted vignette. 

I thought I was done, (and I pretty much was!) but the shadow on the image’s right side was too strong, So, I cloned it out , but that looked strange. Since the cloned data was on its own layer, I simply reduced its opacity. Now I could control that shadow, as if I changed the intensity & placement of the actual fill flash. Now I was done. I always keep the layered files, ya never can tell! I created a JPEG for Martha to give to the Gallery, and now I was done!
