1
Is an electromagnetic energy that travels in a form of a wave with the speed of 186, 000 miles per second.
LIGHT
2
A light tight box designed to block unwanted or unnecessary light from reaching the sensitized material.
CAMERA
3
Is the light gathering mechanism of the camera that collect the reflected light coming from the object to form the image.
LENS
4
Composed of a highly sensitized chemical compound which is capable of being transformed into an image through the action of light and with some chemical processes.
SENSITIZED MATERIALS
5
Is the process necessary for reducing silver halides into a form so as a latent image and a positive image be made resulting to what we called Photograph.
CHEMICAL PROCESS
6
Is defined as an electromagnetic energy with the speed of 186,00 miles per second. Its wave travel is said to be characterized in certain extent based on velocity, wavelength and frequency of the number of vibration of the wave per second.
LIGHT
7
Is a form of energy, commonly refers to electromagnetic radiation that can be detected by human eye.
LIGHT
8
Of visible light as measured in nanometers (nm) where 1 nm = 1 billionth of a meter (10-9 meters). ✓ The wavelenght of visible light is between 400-700 nm. ✓ The combined effect of the complete range of radiation between 400-700 nm appears as white light to human eye.
THE WAVELENGTH
9
Is the type of light that produces different sensation when reach the human eye. It is the of light, which is capable of exciting the retina of the human eye. (400-700 millimicron or nanometer)
VISIBLE LIGHT
10
Lights in which their wavelength are either too short or too long to excite the retina human eye i.e. X-ray, Ultra-violet and Infra-red lights.
INVISIBLE LIGHT
11
This is electromagnetic energy having wavelength that range from 1-30 millimicrons. Object, is opaque (light cannot pass through ex. metal, wall, etc.) as seen by the naked can be penetrated rays
XRAYS
12
Ranges from about 200 to 400 millimicrons wavelength. This ray of light is also invisible like the infrared. Its position falls between X-ray and Visible wavelength. Designed to photograph fingerprints in multi colored background, documents that are altered, decipherment of erase writing and developing invisible writings
ULTRAVIOLET RAYS
13
Produces different sensations when they strike the human eye. The color of the different objects are usually mixture of light, of various wavelenght, and not a special color.
VISIBLE LIGHT
14
Is not a color or any kind of red. It is invisible ray and detected by the skin as
INFRARED RAYS
15
It is the deflection or bouncing back of light when it hits a surface.
REFLECTION
16
Is the angle between a light ray and the normal when the ray leaves the surface
ANGLE OF REFLECTION
17
Is the angle between a light ray and the normal when the ray Hits the surface
ANGLE OF INCIDENCE
18
The bending of light when passing from one medium to another.
REFRACTION
19
The bending of light when it hits a sharp edge of an opaque object. It is also described as the apparent bending of waves around small obstacles and the spreading out of waves past small openings.
DIFFRACTION
20
The nature of light to be absorbed in the process of dark sufaces. Example: Wearing a black shirt on a sunny day makes you feel hotter because the dark fabric absorbs more light (and heat).
ABSORPTION
21
Is when the light hits a transparent glass which would allow the light to pass through medium
TRANSMISSION
22
A lighting condition wherein objects in open space cast a deep on uniform shadow.
BRIGHT LIGHT
23
A lighting condition wherein the objects in open space cast a transparent shadow
HAZY LIGHT
24
A lighting condition wherein the objects in open space cast no shadow
DULL LIGHT
25
Can be used to enhance or replace natural light, such as during hazy or dull outdoor conditions.
ARTIFICIAL LIGHT
26
These lights provide a steady stream of illumination, making them suitable for situations where constant lighting is needed.
CONTINUOUS DURATION
27
Tube-shaped lamps coated with fluorescent powder. They emit a consistent, diffused light.// DIFFUSED LIGHT USED IN HOMES
FLUORESCENT LAMPS
28
Bulbs with a filament inside that glows when electricity passes through it. These produce a warm, yellow light.// HOUSEHOLD LIGHTING
INCANDESCENT LAMPS
29
High-intensity bulbs designed to provide powerful, focused light. They are used in studio settings.
PHOTOFLOOD LAMPS
30
These lights are used for brief, intense bursts of illumination, typically for capturing fast-moving subjects or creating specific effects.
SHORT DURATION
31
Produce light through a chemical reaction. They are no longer widely used but were once common for quick, bright flashes.
FLASH BULB
32
Produce light using a high-voltage electrical discharge through a gas-filled bulb.
ELECTRONIC FLASH
33
A cube with multiple flash bulbs for broad, even lighting.// MOSTLY OBSOLETE
STROBE CUBE
34
A flash that automatically fires in sync with the main flash of the camera or another flash unit.// ADDITIONAL LIGHT
SLAVE UNIT OR SLAVE FLASH
35
A circular light that surrounds the camera lens, providing even illumination with minimal shadows.// MACRO PHOTOGRAPHY
RING LIGHT
36
Additional flash units that can be attached to a camera or used separately to provide extra lighting.
ACCESSORY FLASH UNIT
37
Requires the photographer to manually set the exposure based on the distance and light Conditions.// Provides full control
MANUAL FLASH
38
Uses sensors to adjust light output based on the distance to the subject. Automatically adjusts the flash duration and intensity.// CONTROL AMOUNT OF LIGHT
AUTOMATIC FLASH
39
A flash unit integrated into the camera body.// CONVENIENT FOR QUICK
BUILT-IN FLASH UNIT
40
A flash unit that is placed away from the camera to create more dynamic lighting effects. The shutter speed that is compatible with the flash to ensure that the entire image is evenly// ALLOWS MORE CREATIVE
