3 Camera PartsCamera Parts

4 SLR CameraSLR Camera  SLR stands for single-lens reflex.

5 Lenses  Two types of lenses  convex  concave  An SLR uses a convex lens

6 Inverted ImageInverted Image  When light passes through the camera lens, the image is upside- down, or inverted.

7 Focal LengthFocal Length  The farther away the lens from the object, the larger the image.  The closer the lens to the object, the smaller the image.

8 The FocusThe Focus  How clear or blurry an image is depends on the focus.

9 Light  Light travels at 186,292 miles per second.  Primary source is sun ~ natural light.  A wave that travels in a straight line.

10 Light  When light waves encounter an object, they may be reflected or refracted.

11 Light  Reflection : when light waves bounce off an object.  When light passes through an object, the speed of light changes and the waves are refracted.

12 Refraction

13 Light through glassLight through glass  When a glass allows enough light through it to see an object clearly, the glass is transparent.  When light can barely pass through a glass, the glass is translucent.  When light cannot pass through a glass, the glass is opaque.

14 Light through lensLight through lens  When light passes through a prism, it breaks down into the electromagnetic spectrum.  This breakdown of light into different wavelengths produces bands of visible light.


16 Light  White light is the combination of all the colors  Black is the absence of colors or the absence of light

17 Picture formationPicture formation  Cameras can use the media of film, which requires a chemical process to form a picture.  Or the camera uses an electrical current to form a digital picture.

18 Sensors  Digital pictures are formed by electrical semiconductors also known as sensors

19 Film NegativeFilm Negative  A negative is where lighter areas appear darker and darker areas appear lighter – which is then converted into a positive image in printing.

20 Colors  The 3 colors which combine to produce all colors:  Red  Blue  Yellow

21 Grains  The pictures produced on film are made of grains, which are circles of color

22 Pixels  Digital pictures are made of pixels, which are made of squares.  The amount of colors in the squares is called saturation.  If a digital picture is blurry/out-of-focus, it is called pixilation.

23 Iris  The hole that lets light into a camera is called an iris.

24 Shutter  The curtain that goes up and down in a camera is called the shutter.  Controls the focus and the light/exposure.

25 Aperture  The part that controls the size of the hole in the camera is the aperture.  It is like the iris of the eye.

26 Focus  To lock the focus, press the shutter button half way down.

27 Pentaprism  A camera uses a kind of prism called a pentaprism.

28 Rule of ThirdsRule of Thirds  The main principal that controls where a subject is found in the frame is called the rule of thirds.  This principal states that you divide your picture into nine equal parts.  There are two vertical lines and two horizontal lines.  The intersection of these lines are called the vertices.


30 Flash  You should be 6 to 10 feet - or 10 footsteps - away from an object for your flash to be effective.  Using a flash outside eliminates shadows in the pictures.
