Analysis of Color Consistency in Retinal Fundus Photography: Application of Color Management and Development of an Eye Model Standard

Color variation in retinal fundus photography represents a significant gap in the standardization of color for fundus cameras. Fundus cameras are used in the context of ophthalmology as a method of documenting a patient’s retina to monitor pathology over time.This form of ophthalmic imaging is also used in clinical trial research and, increasingly, teleophthalmology, as a stand in for an in-per...

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 ...

Focus: Natural Philosophy and Instrumentality

The mismatch between common representations of “science” and the miscellany of materials typically studied by the historian of science is traced to a systematic ambiguity that may itself be traced to early modern Europe. In that cultural setting, natural philosophy came to be rearticulated (most famously by Francis Bacon) as involving both contemplative and practical knowledge. The resulting te...
