Bob Rosinsky from Top Dog Imaging walks through the extraordinary process of restoring a badly damaged 1870s tintype (such as the Billy the Kid image that was the subject of a recent record-setting auction
) using modern, high-tech techniques, such as a polarized strobe and ultra-high-rez camera. He hints at even more advanced techniques employing X-rays, UV and infra-red light.
My standard operating procedure is to use an ultra-high resolution camera combined with a top-of-the-line macro lens to photograph tintypes. I use strobe lights to illuminate the artwork. Strobes produce "hard" light, much like the sun on a clear day. In addition to the strobes, I place a polarizer over the camera lens and polarizer gels over the strobe lights. This eliminates all reflections and enables the camera to pick up a greater tonal range along with more detail...
Restoring a Photograph from the 1870s
One advantage of using a scanner to digitize a tintype is that it will smooth out surface imperfections and micro details thus reducing the amount of time it takes the retouch artist to produce a clean, albeit low fidelity, image -- somewhat analogous to hearing a Beethoven symphony on AM radio.
Jan Fröjdman used HiRISE satellite data from Mars to create this beautiful and detailed flyby of the planet. Liz Stinson writes that stitching it together took months. For Fröjdman, creating the flyover effect was like assembling a puzzle. He began by colorizing the photographs (HiRISE captures images in grayscale). He then identified distinctive features in […]
Brian Macintosh made an Icon Machine that generates procedural potions. Gotta drink ’em all! Source code.
The only thing at Hypernom.com appears to be a 3D fractal cage. You can move toward the edge with the WASD and arrow keys. But as you approach it, a new level of detail pops in and you seem no closer to the perimeter. Approached as a game, there is a “trick” to escaping—but I’m […]
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
