These media appear to be distinctly different with respect to their physical and chemical properties. Yet the Separation between them becomes more blurred as information recorded in one medium can be copied readily onto another. Conventional examples are the miaofilming of newspapers, or the photocopying of whole fragile books. Modem scanning techniques allow any form of information whether pic...

In bite mark analyses, the initial photograph is critical for the collection and presentation of evidence. A high-contrast film technique previously used primarily in the graphic arts field has been refined and applied to forensic odontology. The process, called toneline, reduces the interpretational bias of the investigator and yields a transparent overlay with a photographic outline of the bi...

Gross and microscopic studies of the auriculoventricular conduction system were performed in 60 human hearts. A unique technic is introduced which will produce a photographic. record of undistorted serial sections through a block containing the auriculoventricular node, auriculoventricular bundle and branches. By projecting the completed film as a motion picture, the course and changing relatio...

The photochromic property of bacteriorhodopsin films is exploited in the application of a focusing schlieren optical system for the visualization of optical phase information. By encoding an image on the film with light of one wavelength and reading out with a different wavelength, the readout beam can effectively see the photographic negative of the original image. The potential advantage of t...

The most-watched NOVA documentary ever made and a revolution in the understanding of human development, The Miracle of Life (abbreviated Life) employs the most current developments in endoscopic and microscopic technology to capture the intricacies of human development. Narrated by Anita Sangiolo and vividly illustrating the most minute and hard-toreach parts and processes of living systems, th...

PHOTOGRAPHY of fluorescence in retinal vessels as described by Novotny and Alvis affords a means of studying the dynamic characteristics of the retinal circulation.' Studies in our laboratory and by other investigators 2 using this method or a modification have demonstrated retinal vascular phenomena that would be difficult to recognize by ophthalmoscopic visualization alone. The single film ph...

A procedure for fabrication of photomasks on photographic films with minimum feature achievable of about 20 μm, which are particularly suitable for the fast prototyping of microfluidic devices, has been improved. We used a commercial photographic enlarger in reverse mode obtaining 10:1 reduction factor with error less than 1%. Masks have been characterized by optical transmission measurement an...

Although the ECG-gated radionuclide blood pool scan (GBPS) has become an established method for studying regional myocardial wall motion, it is usually performed with the aid of an expensive computer system. A simple, inexpensive method was developed to view gated radionuclide blood images by a film loop and a photographic motion detection (PHOMOT) technique. These techniques were compared with...
