CAMERAi) TYPES OF CAMERA

ii) CAMERA FUNCTION

Prepared by :Muhammad Asri bin Azuddin

WHAT IS CAMERA?• A camera is an optical instrument for recording images,

which may be stored locally, transmitted to another location, or both.

• The images may be individual still photographs or sequences of images constituting videos or movies.

• The word camera comes from camera obscura, which means "dark chamber“.

• The modern photographic camera evolved from the camera obscura. The functioning of the camera is very similar to the functioning of the human eye.

CAMERA OBSCURA

TYPES OF CAMERA

1)PINHOLE CAMERA2)VIEW CAMERA

3)TWIN LENS REFLEX CAMERA (TLR)4)VIEW FINDER CAMERA

5)SINGLE LENS REFLEX CAMERA (SLR)

1) PINHOLE CAMERA

• A pinhole camera, a variation of Camera obscura.

• A simple camera without a lens and with a single small aperture, a pinhole – effectively a light-proof box with a small hole in one side.

• Light from a scene passes through this single point and projects an inverted image on the opposite side of the box.

1) PINHOLE CAMERA

ADVANTAGES

1.Very in expensive2.Easy to make3.Artistic impression4.Maximum depth of field

1) PINHOLE CAMERA

DISADVANTAGES

1.No control2.Long exposures3.Can not view what the camera sees

2) VIEW CAMERA

• The view camera is a type of camera first developed in the era of the daguerreotype (1840s-'50s) and still in use today, though with many refinements.

• 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.

2) VIEW CAMERA

Movement

2) VIEW CAMERA

ADVANTAGES1.Allow for perspective and distortion control of landscape and architecture.2.Large film size allows for very large prints.3. Variety of special use attachments.4.Directly viewing of the image.5.Wide selection of lenses.

2) VIEW CAMERA

DISADVANTAGES•Lots of control •Very large and heavy camera•Most models require the use of tripod•Image difficult to see on viewing glass•Takes time to set up and use

3) TWIN LENS REFLEX CAMERA (TLR)

• A twin-lens reflex camera (TLR) is 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.

3) TWIN LENS REFLEX CAMERA (TLR)

ADVANTAGES1.Larger film size for high quality enlargement2.Image always visible in viewfinder

3) TWIN LENS REFLEX CAMERA (TLR)

DISADVANTAGES1.Lots of control2.Large size camera3.Many models do not have interchangeable lenses4.Parallax error

4) VIEW FINDER /RANGE FINDER CAMERA

• A rangefinder camera is a camera fitted with a rangefinder: a range-finding focusing mechanism allowing the photographer to measure the subject distance and take photographs that are in sharp focus.

4) VIEW FINDER /RANGE FINDER CAMERA

ADVANTAGES 1.Easy to use2.Focus free3.Small compact camera

4) VIEW FINDER /RANGE FINDER CAMERA

DISADVANTAGES1.Few control2.Low picture quality 3.Parallax error

5) SINGLE LENS REFLEX CAMERA (SLR)

• A single-lens reflex camera (SLR) typically uses a mirror and prism system that permits the photographer to view through the lens and see exactly what will be captured.

5) SINGLE LENS REFLEX CAMERA (SLR)

ADVANTAGES1.No parallax error2.Variety of interchangeable lens3.Variety of controlled adjustment4.Wide range of shutter speed

5) SINGLE LENS REFLEX CAMERA (SLR)

DISADVANTAGES1.Frequently have complicated controls2.Larger size camera3.Shutter and mirror system tend to be noisy
