Water for Photography

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...

Innovative Use of Opsite Flexigrid™ for Digital Photography in Rhinoplasty

Standardization of photography in plastic surgery is fundamental for pre-operative surgical planning, comparative post-operative assessment, and demonstration of surgical results.1 In rhinoplasty, slight changes in patient or camera position can lessen nasal hump, vary nose size, and alter skin tension.2 In order to prevent these common errors, photographic standardization with high-quality equ...

A Short Introduction to Clinical Photography for the Plastic Surgeon

Inverse Lighting for Photography

We introduce a technique for improving photographs using inverse lighting, a new process based on algorithms developed in computer graphics for computing the reflection of light in 3D space. From a photograph and a 3D surface model for the object pictured, inverse lighting estimates the directional distribution of the incident light. We then use this information to process the photograph digita...
