Photography with Color-Coded Apertures

Prism-Based Color Separation for Professional Digital Photography

In the field of silver-halide photography, color separation was explored about a century ago, using filter mosaics, dichroic mirrors, three-shot filtration, and other techniques, before the dominant technology of multi-layered color film emerged. In the field of digital photography, the same techniques are being explored now in conjuction with silicon sensor technology. The three-shot technique...

Structured Light Color Boundary Coding for 3D Photography

In this paper we present (b, s)-BCSL, a new coded structured light method for 3D photography. It employs a sequence of complementary color stripe patterns to define correspondences within a camera/projector shape acquisition system. Unique codes are associated with the boundaries of successive stripes in time. The use of color fully exploits current imaging hardware and makes possible an effect...

The color of water: using underwater photography to estimatewater quality

We describe a model for underwater illumination that is based on how light is absorbed and scattered by water, phytoplankton and other organic and inorganic matter in the water. To test the model, we built a color rig using a commercial point-and-shoot camera in an underwater housing and a calibrated color target. We used the measured spectral reflectance of the calibration color target and the...

Panretinal, high-resolution color photography of the mouse fundus.

PURPOSE To analyze high-resolution color photographs of the mouse fundus. METHODS A contact fundus camera based on topical endoscopy fundus imaging (TEFI) was built. Fundus photographs of C57 and Balb/c mice obtained by TEFI were qualitatively analyzed. RESULTS High-resolution digital imaging of the fundus, including the ciliary body, was routinely obtained. The reflectance and contrast of ...
