"Photoshop" Natural Recordings by Native Speakers
Photoshop is a raster graphics editing software published by Adobe Inc. It is widely used worldwide for various purposes such as graphic design, photo editing, and digital painting.
To make something more sensitive to light, especially by increasing its susceptibility to a photochemical reaction, often used to describe a substance that changes color or reacts visibly to light.
A chemical that makes something sensitive to light, especially to ultraviolet or laser light.
Photosensitivity refers to an abnormal sensitivity to light, often resulting in certain reactions or symptoms after exposure to light, especially sunlight. This can include symptoms such as:1. Urticaria (hives)2. Vasodilation (dilated blood vessels)3. Itching4. Erythema (redness of the skin)5. Skin inflammationIt can be caused by a variety of factors, including:1. Certain medications2. Medical conditions (e.g. lupus, multiple sclerosis)3. Allergies4. Sensitivity to specific wavelengths of light (e.g. UV light)Individuals with photosensitivity may experience adverse reactions when exposed to sunlight, artificial light sources, or medical procedures that use high-intensity light.
To make someone or something more sensitive to light, so that they are more likely to be affected by it.For example: "The paint was designed to photosensitize the wood, allowing it to darken in the sunlight."Or: "Some people's skin can photosensitize, making them more prone to sunburn or blistering in bright light."This term is most often used in medical contexts, but it can also be applied more broadly to describe any substance or material that becomes more reactive or sensitive to light when exposed to certain wavelengths.
A photosensitizer, also known as a photosensitizing agent, is a chemical that becomes activated and transfers its energy to another molecule, usually oxygen, to produce a reactive form of oxygen that is toxic to living cells. This is often used in photodynamic therapy (PDT) to treat certain types of cancer or other diseases.
The term "photosensitizing" refers to the process or property of making a substance or tissue more susceptible to the effects of light. In other words, it is the sensitization of a material or organism to become more responsive or reactive to light radiation.In medical contexts, photosensitizing agents are substances that absorb light energy and transfer it to a target tissue, causing damage or a specific response. This is commonly used in medical treatments, such as photodynamic therapy, where light is used to target cancer cells, bacteria, or other abnormal cells.In simple terms, photosensitizing describes the way in which light can trigger a reaction or change in a substance or living tissue, often with the aid of a photosensitizing agent.
A photo shoot is an occasion or session during which a photographer takes pictures of a subject, typically using a camera, to create photographs. This can be for personal, social, commercial, or other purposes.In the context of fashion, a photo shoot often involves a model posing in outfits or accessories to showcase a brand or designer's work. It can also be used to photograph portraits, landscapes, or everyday life scenes.Key aspects of a photo shoot may include:<em> Pre-production planning to determine themes, locations, and logistics</em> Coordination of subject wardrobe, makeup, and hair styling<em> Capturing images using a camera, often in conjunction with lighting, angles, and creative vision</em> Post-production editing to refine or enhance the images taken during the shoot.Regardless of the purpose, the primary goal of a photo shoot is to create visually appealing and effective photographs that convey a message, tell a story, or showcase a distinct image or style.
Photoshopping refers to the artistic or retouching process of modifying an image using a software, typically Adobe Photoshop, to alter its appearance and make changes to its layout, colour, contrast, and brightness, among other features.
Photostabilisers are chemicals that are added to materials, such as paints, coatings, adhesives, and plastics, to protect them from the effects of sunlight and ultraviolet (UV) radiation. Their purpose is to prevent or slow down the degradation of these materials caused by the interaction with sunlight, heat, or other environmental factors.Photostabilisers work by absorbing or scattering UV radiation, thereby reducing the amount of energy that is available to cause chemical reactions in the material. This helps to prevent the breakdown or degradation of the material, which can lead to changes in its appearance, texture, or performance.Common examples of photostabilisers include:<em> UV absorbers (such as benzotriazoles and benzophenones)</em> UV reflectors (such as pigments and fillers)<em> Quenchers (substances that deactivate free radicals and other reactive intermediates)</em> Antioxidants (substances that prevent the formation of reactive oxygen species)Photostabilisers are widely used in various industries, including:<em> Coatings: painting, enamels, varnishes, and inks</em> Plastics: injection-molded parts, film, cosmetics, and personal care products<em> Textiles: fabrics, dyes, and finishes</em> Adhesives: caulks, sealants, and bonding agentsBy using photostabilisers, manufacturers can extend the lifespan of materials and reduce the risk of premature degradation, which can lead to economic losses and environmental problems.
Chemicals that slow down the breakdown of photographic emulsions by light and resistance to fading, allowing permanent images to be stored.
A photostat or Xerox is a copy of a document made by photography, typically an exact reproduction of a written or printed page. It is essentially a photographic copy of a document.
Photostatic refers to something that is exact or completely accurate, often in relation to a photograph or other visual representation. It can also imply a sense of indisputable or conclusive evidence, often used to describe a situation where the facts are clear and cannot be disputed.
Photosynthate refers to a chemical produced by green plants, algae, and some bacteria during photosynthesis, the process by which they convert light energy into chemical energy. It is a compound that contains energy produced by the synthesis of glucose from carbon dioxide and water in the presence of sunlight. In other words, photosynthate is the end product of photosynthesis, which is used as energy by the plant itself and also made available to other organisms in the ecosystem through the process of decomposition or herbivory (e.g., consumption by animals).
