    Improved photographic prints with a linear radial transmission filter

    Get PDF
    Linear Radial Transmission Filter (LRTF) is easy to use and yet results in prints which depict more information contained in negative than can be shown by direct printing. LRTF is optical-quality filter which has maximum transmission in center and linear drop in transmission radially out from center

    Get PDF
    Data from the scientific payload, OSTA 1, is available. Images of the Earth's surface taken from the Shuttle Imaging Radar-A were processed, and can be obtained in the form of photographic prints, negatives, or positive transparencies. Magnetic tapes containing data for the ocean color experiment and the Shuttle multispectral infrared radiometer are also available

    Rediscovery of the Florida Scorpionfly, Panorpa floridana Byers (Mecoptera: Panorpidae)

    Get PDF
    We describe the rediscovery of the Florida scorpionfly, Panorpa floridana Byers (Mecoptera: Panorpidae), at Gold Head Branch State Park, Clay County, Florida, based upon a single, living, adult specimen photographed on 4 November 2010. The hardcopy photographic prints and electronic digital images of this panorpid are the first vouchers for P. floridana in 28 years, the only observation of a living specimen, and the sixth individual known of this seemingly rare Florida endemic

    Infrared Ellipsometry Analysis of Heritage Photographic Prints

    Full text link
    [EN] Focusing on the photographic archive of Julian Carrillo (Mexico), we study and characterize the photographic processes of a set of 13 photographs dated between 1884 and 1925. By using infrared spectroscopic ellipsometry, we classified a selected set of photographs according to its kind of binder. Thus, we recognized for each photograph, the presence of proteins, and therefore, the particular photographic process. Furthermore, we have identified the presence of baryta layer, the use of plasticizer, and the eventual coating utilized to protect the photograph, whose composition was based in natural organic components, mainly shellac, beeswax, or camphorNieto-Villena, A.; Martinez, JR.; Flores-Camacho, JM.; Lastras-Martinez, A.; De La Cruz-Mendoza, JA.; Ortega-Zarzosa, G.; Valcarcel Andrés, JC....

    Get PDF
    The performance and design requirements for a Color Graphic Camera System are presented. The system is a functional part of the Earth Observation Department Laboratory System (EODLS) and will be interfaced with Image Analysis Stations. It will convert the output of a raster scan computer color terminal into permanent, high resolution photographic prints and transparencies. Images usually displayed will be remotely sensed LANDSAT imager scenes

    Method of examining microcircuit patterns

    Get PDF
    Examination of microstructures of LSI and VLSI devices is facilitated by employing a method in which the device is photographed through a darkfield illumination optical microscope and the resulting negative subjected to inverse processing to form a positive on a photographic film. The film is then developed to form photographic prints or transparencies which clearly illustrate the structure of the device. The entire structure of a device may be examined by alternately photographing the device and selectively etching layers of the device in order to expose underlying layers
