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...
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.
When it comes to the uncanny valley of video game characters, the eyes have it. Even as digital characters become increasingly (hyper)realistic, the eyes lag behind. At FastCo Design, Mark Wilson looks at the technological and perceptual challenges of designing eyes with personality: The initial problem with rendering eyes is simply that of light and […]
Alexander Senko wrote Pure Data code that “produces a lissajous figure with different frequency ratios and a phase modulation. The curve generates pitch, harmonics and volume of sound. The inflection points on the curve create rhythmic structures.” I don’t always blog about figures, but when I do, they’re lissajous ones.
