"Photograph" Natural Recordings by Native Speakers
An image produced by a camera, typically recorded on a sensitive medium such as a film plate or an image sensor.
Photogenotoxicity refers to the ability of a substance or agent to generate DNA damage in cells directly through interaction with ultraviolet (UV) radiation, rather than through metabolic activation. This is a significant concern in the field of photobiology and cancer research, as it can lead to the formation of mutations and an increased risk of cancer. Photogenotoxins can be endogenous or exogenous. Endogenous photogenotoxins are produced naturally by the body itself, while exogenous photogenotoxins are substances that originate from the environment. Examples of substances that exhibit photogenotoxicity include:<em> Psoralens</em> Anthranoids<em> Cyclobutanes</em> Nucleoside analogsPhotogenotoxicity is often studied in the context of its relationship to the environmental risk of skin damage or cancer from UVA radiation, as well as its role in the understanding of photochemical processes.In summary, photogenotoxicity is a measure of a substance's ability to damage DNA directly when exposed to light.
An adjective that refers to something related to or resembling glyphic art or notation. However, a more precise meaning of 'photoglyphic' refers to something related to or involving photography.
A very rare word!Photoglyphy is the art of obtaining or creating words or letters, or images (photograms) by the action of light acting upon a silver soil impregnated with sensitised tissue.
Photomorphic(adj.) : not occurring within the living organism; especially of organs or tissues formed or developed outside the organism.
A photogram is a representation or image formed by light rays passing through a translucent object onto a light-sensitive surface, such as photographic paper.
The word "photogrammetric" refers to the use of photographs or digital images to determine the size and shape of objects, their position in space, and the distances between them. It is a technique used in various fields such as architecture, engineering, geography, and remote sensing to create highly accurate 3D models and measurements from 2D images.In photogrammetry, multiple overlapping images are taken from different angles, and then analyzed using specialized software to create a 3D model or orthophoto (a photograph that has been rectified to project a plane onto a rectangular grid). The process typically involves:1. Image capture: Obtaining multiple overlapping photographs or digital images of the target area.2. Orientation: Determining the position and orientation of each image in 3D space.3. Spatial resection: Calculating the positions of control points on the images, which are used to determine the camera's position and orientation.4. Triangulation: Creating a 3D model by connecting the control points and triangulating the surfaces.5. Georeferencing: Matching the 3D model to a geographic reference system, such as a map or GPS coordinates.Photogrammetry has a wide range of applications, including:<em> Mapping and charting: Creating highly accurate maps and charts for navigation and cartography.</em> Building information modeling (BIM): Creating detailed 3D models of buildings and infrastructure for design, construction, and maintenance.<em> Archaeology: Documenting and analyzing archaeological sites and artifacts.</em> Geology: Studying and mapping geological features and processes. Aerial photography: Mapping and surveying large areas from aerial photos.Overall, photogrammetry is a powerful tool for creating accurate 3D models and measurements from 2D images, with applications in many fields where spatial data is critical.
Relating to photography or photography. Example: "The camera took a photographically perfect shot of the sunset."
A photograph is a two-dimensional image created by focusing light rays to form an image on a light-sensitive surface, such as film or a digital sensor. It captures a real-world scene or subject, frozen in time.The term "photographone" was actually the first term used to describe this process, invented by Joseph Nicephore Niepce, a French photographer, in 1826. He used a photographic technique called heliography to create the first permanent photograph, "View from the Window at Le Gras."
