Silver Halide Silver iodide
It is Photography. Photography comes from 2 greek words Photo is the stem that means "light" and graphein is the verb that means "to write" so literally, photography means writing with light
Natural Light (sunlight) and Artificial Light (flashes/studio lights)
yes ; it means to write with light.
The word "photography" comes from the Greek words photoswhich means "light" and graphe' which means "drawing" or "writing," giving us "drawing with light."
im only in 8th grade but in 6th grade i took a photography class [i went to a college program school thing] and if you expose the films to light [besides the red light] the film gets ruined and when you print it out everything is either mostly all white or mostly all black.
Silver Iodine
When someone talks about exposure in photography, they're talking about the level of light in an image. A photograph can be overexposed (too much light), underexposed (not enough light) or well exposed (the light is just right).
professer J. shulze mixes chalk, nitric acid, and silver in a flask; notices darkening on side of flask exposed to sunlight. Accidental creation of the first photo-sensitive compound.
Iodine is used in photography as a component of the silver iodide emulsion that coats light-sensitive film or photographic paper. When exposed to light, the silver iodide undergoes a chemical reaction that forms an image, capturing the light and creating a photograph.
Photochromic refers to a type of lens that darkens when exposed to UV light and clears up when not exposed. These lenses are commonly used in eyeglasses and sunglasses to provide protection from sunlight.
The discovery that silver nitrate changes when exposed to light was first made by Thomas Wedgwood in the early 19th century. He observed the light-sensitive properties of silver nitrate when experimenting with photography.

The flash in photography is significant because it provides additional light to illuminate a scene or subject, especially in low-light conditions. This helps to capture clear and well-exposed images by reducing motion blur and enhancing details.
Light sensitive paper is a type of photographic paper that changes color when exposed to light. It contains light-sensitive chemicals that react to light by darkening in areas exposed to light, creating a visible image. This process is used in traditional darkroom photography to create prints from film negatives.
An incident light meter can be used in photography to measure the amount of light falling on a subject. By pointing the meter towards the light source, it can provide an accurate reading of the light intensity, allowing the photographer to adjust their camera settings accordingly for a well-exposed photograph.
The umbra is the darkens area of an eclipse where there is no light at all.
He invented the calotype which is basically a piece of paper conered in silver iodide, and when exposed to the light the silver reacts and darkens, its a negative picture. this allows people to produce pictures in bulk and copy them and such. so basically he helped further develop photography , other processes and such.
