is the mechanical device that is used to form and record the rays of light (as reflected by the object or subject) on the film inside the light tight box or the camera.

Camera

a light tight (proof) box with a means of forming the image (Lens or Pinhole), with a means of holding sensitized material at one end (Film holder), and with a means of controlling the amount of light needed to affect the film at the other end (Shutter).

Camera

Essential Parts of a Basic camera

1. Viewfinder 2. Camera Body Or light-tight box 3. Film Holder 4. Lens 5. Shutter

it is used to determine what will be included or covered in the picture and serves as the viewing point for all cameras. This will show the entire scene coverage that can be recorded in the film inside the camera. It is usually attached to the top or side of the camera's viewing lens.

Viewfinder

it houses the various parts of the camera and protects the film from light except that which enters through the lens when a picture is taken.

Camera Body or Light-tight box

This refers to the basic parts of the camera that are located at the opposite side or end of the lens of a camera. It is necessary to hold the sensitized material firmly in the correct plane during exposure intervals.

Film Holder

it focuses the light rays from a subject into a reversed, upside-down image on the film at the back of the camera

Lens

it keeps light from the film until you are ready to take a picture.

shutter

Often known to be the “door of the camera”

Shutter

TWO MAIN SHUTTER MECHANISM

1. Focal Main shutter 2. Leaf shutter or diaphragm shutter

it is built into the camera body itself, just in front of the film. It consists of two overlapping curtains that form an adjustable slit or window. When the shutter is released, the window moves across the film, exposing the film as it moves.

Focal-Plane Shutter

It is a type of shutter where thin metal blades whip open, stay open for a fraction of a second, then whip closed again. These are normally built into the lens, though on a few cameras, they are behind the lens. This also forms an adjustable hole, or aperture.

Leaf Shutter

ESSENTIAL CAMERA ACCESSORIES

1. Tripod 2. Cable Release 3. Flash Unit 4. Light Meter 5. Extension Tube 6. Filter 7. Camera Grip 8. Lens Hood

This refers to a triple-leg device that is adjustable to any reasonable extension. This can be used to hold the camera when the camera is bulky or when using a shutter speed lower than one twenty-five of a second (1/25) to prevent the movement that will produce a blurred image in the photograph.

Tripod

This refers to camera accessories that are attached to the shutter release of the camera and used in releasing and closing the shutter to prevent accidental movement of the camera during the exposure period, especially when longer exposure is made

Cable Release

This refers to flash bulbs or electric flashes that synchronize with the opening and closing of shutters. This is very effective in augmenting the adverse lighting condition of the object(s) being photographed.

Flash Units

This refers to a device used in determining the intensity of light that strike the subject and affect the film inside the camera.

Light Meter

This refers to a device used in photographing a minute object. It is attached to the lens board of the camera, and the lens is attached to it when close-up photography is necessary.

Extension Tube

This refers to a transparent medium that transmits and absorbs different wavelength of lights usually made of glass or gelatine material placed in front of the camera lens.

Filter

This refers to a device used to hold the camera firmly so as to prevent the vibration or movement of the camera during the exposure period. It is attached to the body of the camera, and sometimes the flash unit is attached to it.

Camera Grip

This refers to a device used to eliminate some reflections of light which might destroy the image cast of the object(s), especially when the light is coming from the top or side position of the camera. It is usually mounted in front of the lens barrel.

Lens Hood

It has a simple design and construction, usually home-made. It consists of a box with a small aperture that functions as a lens at one end, with the image being projected onto the film at the other end

Pinhole Camera

Who invented Pin Hole Camera

Alhazen

It refers to anything in the format of 4x5 inches (102x127 mm) or larger.

Lager Format Camera

These cameras are most frequently used for commercial, architectural, or landscape photography.

Larger Format Camera

Who is the first person developed the 4x5 Camera

Daguerre

it comprises a flexible bellows that forms a light-tight seal between two adjustable standards, one of which holds a lens and the other a viewfinder or a photographic film holder

4x5 View Camera

It refers to the increased size of the negative film. In the 35-mm camera world, your negative is traditionally 24x36 mm.

Medium Format Camera

a type of camera with two objective lenses of the same focal length, one of the lenses is the photographic objective or “taking lens” (the lens that takes the picture), while the other is used for the viewfinder system, which is usually viewed from above at waist level.

Twin Lens Reflex(TLR) Camera

a type of camera with bellows that can be folded so that the camera occupies less space when not in use.

Folding Camera

Who invented 35 mm Camera

Oskar Barnack

it refers to cameras that produce a negative that is 35 mm. This type of camera is preferable when you need ease of movement and the ability to produce a larger number of images between loadings.

Small Format Camera

this type of camera was developed to overcome the problems with TLRs and compact cameras. The design avoids parallax error completely by using a single lens both for viewing and focusing.

Single-Lens Reflex Camera

a camera that is mechanically simple; the most common form is a cardboard or plastic box with a lens on one end and film on the other.

Box Camera

This camera has focusing mechanism allowing the photographer to measure the subject distance and take photographs that are in sharp focus.

Rangefinder Camera

Who developed the Polaroid Instant Camera?

Edwin H. Land

a still camera designed primarily for simple operation.

Point and Shoot Camera or Compact Camera

these cameras offer higher-end hardware, full manual controls, and better performance than average point-and-shoot cameras.

Advanced Point and shoot Camera

a camera that takes video or still photographs by recording images on an electronic image sensor

Digital Camera

a camera combining the parts of a single lens reflex camera and a digital camera back, replacing the photographic film

Digital Single Lens Reflex Camera

a compact camera that is airtight, so they can function above or below water.

Water Proof Camera

is the capturing of an image on film or digital sensor through the use of light

Exposure

What are the three factors needed for exposure

Aperture Shutter Speed ISO OTHERWISE KNOWN AS THE "EXPOSURE TRIANGLE"

The length of time a camera shutter is open to expose light to the camera sensor or film.

Shutter Speed

FUNCTIONS OF SHUTTER

1. Controller of Light 2. Controller of Motion

A hole within a lens, through which light travels into the camera body. The larger the hole, the more light passes to the camera sensor.

Aperture

FUNCTIONS OF APERTURE

1. Controller of Light 2. Controller od Depth of Field

keep the shutter open as long as the shutter release is held

Bulb

keep the shutter open until the shutter release is pressed again.

time

A hole within a lens, through which light travels into the camera body. The larger the hole, the more light passes to the camera sensor

Aperture

It also controls the depth of field, which is the portion of a scene that appears to be sharp

Aperture

is the area of acceptable sharpness in a photograph or the area from near to far in a scene that is acceptably sharp in a photograph.

Depth of Field

Is also defined as the distance from foreground to background that is in acceptable focus

Depth of Field

A way to brighten your photos if you can’t use a longer shutter speed or a wider aperture.

ISO

This means that changing one part of the relationship (the aperture or shutter speed) requires changing the other part of the relationship (the ISO), to maintain the exact exposure.
