Photoshop
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.
Photoshopped
Being photoshopped typically means that an image or a part of an image has been digitally altered or manipulated using a computer software, usually to conceal or enhance certain features, such as a person's appearance, to create a fake or misleading representation.
Photoshopping
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.
Photosphere
The photosphere is the visible surface of the Sun or other star, which is the layer of plasma from which light is emitted. The photosphere is the layer of the Sun or other stars that we can see and is the layer that produces the light we receive from them. It is the outermost layer of the Sun's interior and is the layer that we can observe using telescopes. The photosphere is about 500 km thick and is cooler than the hotter layers of the Sun's interior.
Photostabilisers
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.
Photostabilizers
Chemicals that slow down the breakdown of photographic emulsions by light and resistance to fading, allowing permanent images to be stored.
Photostat
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
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
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).
Photosyntheses
Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of organic compounds, such as glucose. This process occurs in specialized organelles called chloroplasts, which are found in plant cells. Photosynthesis involves the conversion of carbon dioxide and water into glucose and oxygen through a series of light-dependent and light-independent reactions.
Photosynthesis
Photosynthesis is the process by which plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of organic compounds, such as glucose. This process occurs in specialized organelles called chloroplasts and requires water, carbon dioxide, and sunlight to produce oxygen and glucose.
Photosynthesise

Photosynthetically
Producing or able to produce food from sunlight, for example through photosynthesis.
Photosystems
In biology, a photosystem is a large, light-absorbing molecule complex that plays a central role in the process of photosynthesis. It is the site where light energy is absorbed and converted into chemical energy.Photosystems are found in the thylakoid membranes of chloroplasts in plant cells and are composed of proteins and pigments, including chlorophyll and other accessory pigments. They are responsible for driving the transfer of electrons during photosynthesis, which ultimately leads to the production of ATP and NADPH, the energy carriers that power the conversion of CO2 into glucose.There are two main types of photosystems: Photosystem II (PSII) and Photosystem I (PSI). PSII is responsible for absorbing light energy and transferring electrons to a special molecule called plastoquinone. PSI, on the other hand, uses the energy from PSII to convert light energy into a high-energy molecule called ATP.In summary, photosystems are complex molecular structures that are essential for the process of photosynthesis, converting light energy into chemical energy that can be used by plants to grow and thrive.
Phototactism
Phototactism (or photoactism) is a rare term referring to a stimulus-response reaction to light. It can be seen as a form of phototropism, a phenomenon where an organism grows or moves towards or away from light. However, phototactism specifically describes a nervous response wherein an animal senses and reacts to light using its skin or other bodily tissues.For example, some invertebrates, such as sea creatures and certain worms, exhibit phototactic responses. When light is applied to their sensitive skin, they move towards (positive phototactism) or away (negative phototactism) from the light source in a reflex reaction. This is different from phototropism, which involves the actual growth towards or away from light sources, rather than just a reflex movement.
Phototaxis
Phototaxis is the movement of an organism in response to the direction, magnitude, or quality of light. The movement is usually towards the source of light, a phenomenon called positive phototaxis, or away from the light, a phenomenon called negative phototaxis.
Phototherapeutic
Phototherapeutic refers to the use of light to treat or cure illnesses, injuries, or conditions. It involves the application of light, such as ultraviolet (UV), infrared (IR), or laser light, to stimulate healing, reduce pain, or alleviate symptoms. This can include various forms of phototherapy, including:1. Laser therapy: Using high-intensity light to treat pain, inflammation, and tissue damage.2. Low-level laser therapy (LLLT): Applying low-intensity light to stimulate healing and reduce inflammation.3. Photodynamic therapy (PDT): Using a special light-sensitive medication, combined with a certain wavelength of light, to target and destroy cancer cells.4. Rejuvenation therapy: Using light to promote wound healing, improve skin texture, and reduce signs of aging.5. Pain relief: Treating chronic pain, arthritis, and other conditions with specific wavelengths of light.Phototherapeutic approaches can be applied in various settings, including medicine, dentistry, and veterinary care.
Phototherapy
Phototherapy is a type of treatment that uses light to promote healing, relaxation, and improved mood. It typically involves exposure to specific wavelengths of light, often in a controlled environment such as a phototherapy lamp or a light panel.There are several forms of phototherapy, including:<em> Healing Light Therapy: used to reduce pain, inflammation, and stress by promoting relaxation and reducing tension in the body.</em> Seasonal Affective Disorder (SAD) Therapy: used to treat symptoms of SAD, such as low mood and fatigue, by increasing exposure to bright light.<em> Skin Therapy: used to treat skin conditions like acne, eczema, and psoriasis by using UV or blue light to reduce bacteria and inflammation.Phototherapy can be used to:</em> Improve sleep quality<em> Reduce stress and anxiety</em> Enhance mood<em> Relieve pain and inflammation</em> Improve skin health
Photothermal
"Photothermal" refers to the interaction between light and heat. It typically involves the conversion of light energy into heat energy through various physical or chemical processes.For instance, in photothermal therapy, a certain wavelength of light is used to generate heat within cells or tissues, often for therapeutic purposes, such as killing cancer cells or relieving pain.In astronomy, photothermal effects can refer to the heating of planetary surfaces by the absorption of sunlight, which can have significant implications for the study of planetary climates and geology.Overall, the term "photothermal" encompasses a range of phenomena where light serves as the primary energy source for generating heat.
Photothermolysis
Photothermolysis is the selective heating of a target area of skin by high-intensity pulsed light (IPL) or a laser. It is a non-invasive treatment used to minimize the appearance of hair, pigment or vascular lesions, and/or to kill bacteria in the skin

Phototopography
Looking up the word "phototopography".Phototopography refers to the study of the relations between the appearance of light and dark areas in images of the Earth's surface and their relation to to topography.
Phototoxic
Phototoxicity, often referred to by its older term photo-toxicity, is an injury to living tissue as a result of exposure to light. Phototoxicity is often compared with phototoxic dermatitis, cutaneous phototoxicity and cutaneous phototoxic eruption.
Phototrophic
Phototrophic refers to the process or organisms that produce their own food through the use of light energy. This is a characteristic of plants and some other organisms such as algae and cyanobacteria, which contain chlorophyll, a pigment that captures light energy to power photosynthesis.
Phototrophy
Phototrophy refers to the ability of certain organisms, such as plants and some bacteria, to produce their own food using light energy from the sun. This is done through a process called photosynthesis, which involves the conversion of light energy into chemical energy in the form of glucose. Phototrophy is a key characteristic of autotrophic organisms, which are able to produce their own food and sustain themselves without relying on heterotrophic organisms that consume other organisms or organic matter for energy.
Phototropic
Having a positive response to the direction or intensity of light, that typically involves the growth response of an organism (e.g., a change in stem or root orientation) in which the part of the organism that is away from the light source elongates more than the part closer to the light source, resulting in bending of that part toward the light source.
Phototropin
Phototropin is a type of photoreceptor protein found in plants, responsible for detecting blue light and controlling plant growth and development. It plays a key role in phototropism, the phenomenon of plants growing towards or away from light sources. Phototropin is particularly important for regulating plant responses to light, such as cell elongation, cell division, and chloroplast movement, which help plants position themselves optimally to maximize their exposure to light.
Phototropism
Phototropism is the directional growth response of a plant to light. It's a form of tropism, which is a broader term that describes growth in response to physical stimuli, such as sunlight, gravity, and water. Phototropism is observed in plants, where they grow towards or away from light sources in an effort to optimize their exposure to light for photosynthesis to occur.There are two types of phototropism:1. Positive phototropism: This is where the plant grows towards the light source. This is typically observed in stem elongation, leaf growth, and flower orientation.2. Negative phototropism: This is where the plant grows away from the light source, often seen in roots and hypocotyls.Phototropism is usually controlled by plant hormones, particularly auxins, which are a class of plant growth regulators that help regulate cell elongation and division.
Phototypes
Phototypes refers to the art or process of preparing photographs for reproduction or printing. It can also be used to describe photographs printed using a phototype compositor, an early digital printing device from the 1960s and 1970s that combined several photographic images into a single piece of text.
