A professional who specializes in taking pictures, especially for pay or as a career, often using a camera.
Relating to the art or practice of taking photographs, or to the production of photographs.
Relating to photography, especially in a literal or detailed sense; relating to the process of photography.
Relating to photography or photography. Example: "The camera took a photographically perfect shot of the sunset."
The verb "photographing" is the present participle of the verb "to photograph", which means:<em> To take a photograph or pictures of something or someone using a camera.</em> To capture the image of something or someone using photography techniques.Example sentences:- She is photographing the sunset for her art project.- He is photographing the wildlife in the jungle for a nature documentary.
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."
Photography is the art, science, and practice of creating durable images by recording a two-dimensional medium, typically on film or electronic sensors, by means of a lens focusing the captured light onto a light-sensitive surface or media.
A photogravure is a method of making images using etching, but with a photographic process instead of drawing or engraving. It involves coating a plate with a light-sensitive material and exposing it to light through a photographic negative, which causes the areas that are exposed to light to be etched while the unexposed areas remain intact.An image is created by applying ink to the etched plate and running it through a printing press, transferring the image onto the paper. The result is a high-quality, detailed print with the look and feel of a traditional etching.Photogravure was popular in the early 20th century for book illustrations and posters, as well as for high-end advertising and art prints. It was particularly valued for its ability to produce detailed, high-contrast images with a range of tonal values, similar to traditional etchings made by hand.
Photoheterotrophic refers to photosynthetic organisms, such as algae, that use both light energy from the sun (photo) and chemical energy from an external source, often organic compounds (heterotrophic), to produce their organic matter and energy.
"Photoinduced" refers to a change or reaction that is triggered or initiated by light. It describes a process or phenomenon in which the absorption of light leads to an energy transfer or reaction in a system, often resulting in a change in its chemical, physical, or behavioral properties. This can occur in a variety of contexts, such as photochemistry, photobiology, or photophysics.
A photoinitiator is a compound that, when exposed to light of a particular wavelength, undergoes a chemical reaction or change that triggers a larger chemical reaction in a system. It is commonly used to initiate polymerization in photopolymerization, where it is illuminated by ultraviolet (UV) light or visible light to initiate the curing of inks, adhesives, resins, or other materials.Photoinitiators are usually substances that contain a tertiary amino group (-N-) or an acetone group (-CO-), which are sensitive to UV light and undergo a transition from the ground state to the excited state when excited by UV radiation. This transition is followed by a reaction that activates the photoinitiator, which then initiates a chain reaction of polymerization, curing, or cross-linking of the surrounding material.Common examples of photoinitiators include benzoin ethers, acylphosphine oxides, and amino ketones. They are widely used in various applications such as:1. Dental materials: to create dental composites and resins2. Adhesives: to cure adhesives for bonding materials3. Inks and coatings: to cure inks and coatings for printing and painting4. 3D printing: to cure photopolymers for 3D printing5. Fiber optics: to cure optical fibers and coatings.
A photoirritant is a chemical that, when excited by ultraviolet (UV) radiation, is highly reactive and can cause skin irritation or allergic reactions. This means that when exposed to sunlight or artificial sources of UV radiation, the chemical reacts and becomes a skin irritant, potentially causing redness, itching, or other uncomfortable symptoms.
Photojournalism is the practice of using photographs to tell news stories and convey information to the public. It involves the use of photographs to illustrate news articles, assign meaning and context to events, and provide a visual record of historical events.Photojournalism often shares similarities with documentary photography and uses techniques such as observational, intuitive, and interpretative approaches to capture news stories. It can be found in professional news sources, such as newspapers, magazines, and websites, as well as in other forms of media like video and social platforms.The primary goals of photojournalism are to record truthfully and responsibly: archival of news stories, humanizing an issue, voicing perspectives and emotions, and fostering empathy and dialogue, all while adhering to high ethical standards.Through photojournalism, photographers aim to inform people about current events and cultural issues, raising awareness, promoting understanding, engaging people in discussions, and inspiring critical thinking and action.
