The document discusses different types of lighting used in photography and film production. It describes the key light, fill light, and backlight, which are the three main lights used to illuminate a subject from different angles and provide depth. The key light acts as the main light, the fill light reduces shadows, and the backlight provides subtle highlighting. Together these lights can make a subject appear three-dimensional. The document also explains other types of lighting like general, task, accent, and street lighting used in different contexts.

3. It is usually the strongest and
has the most influence on the
look of the scene.
The key light is placed to one side of the camera/subject so
that this side is well lit and the other has some shadow.
It provides excellent modelling by highlighting the shape and
contours of the subject.
It provides hard light, like that from the sun on a clear day: a
bright light with hard-edged shadows.

4. It is used to fill the shadows created by the key. The fill will
usually be softer and less bright than the key and casts soft
indistinct shadows.
Its light can be likened to
indirect sunlight or reflected
light from the environment.
It is sometimes referred to as the 'highlight' as it is often used
to give a sheen or highlight to an actor's hair.

5. Rather than providing direct lighting (which the key and fill
give), its purpose is purely for modelling – to provide definition
and subtle highlights around the subject's outlines.
This helps separate the subject from the background and give
a three-dimensional look.

6. key light only
the key light has been placed to
the right of the camera and has
created very sharp shadows.
It looks okay – is identifiably an apple – but doesn't show
any real depth.

7. The fill light is usually
on the opposite side
of the camera from
the key, so in this
case it is on the left.
As it should be a soft light (created by use of filters or diffusers)
the effect is similar to the key except the shadows are less
defined. The apple looks flat and artificial.
fill light only

8. Using both key and fill gives that all important depth so that
the image looks more three-dimensional.
key + fill

9. The backlight provides very subtle highlighting to the
apple, most of which is in darkness.

10. Beautiful! A
complete view of
the apple.
a fourth light could be used at the back to remove the
remaining shadows.

12. Is also known as Ambient lighting; is the overall light inside
working plane. This is the lighting that light the main whole
area moderately. This type is commonly seen in markets &
small shops.
The arrangement is typical and lighting level is uniform in all
areas. Overall uniformity can be easily achieved by using
General lighting.

14. Can be relate with task light where
we need to highlight a specific small
working area with controllable beam.

15. It needs to be glare-free. Effective
task lighting enhances visual clarity
and keeps the eye from getting tired.
Several strategies can be apply to
achieve task lighting some are below:
1. Localized avg. lighting, where lamp supplies both ambient
light & task light
2. Freely adjustable task light
3. Asymmetric task light to avoid the glare factor.

16. Lighting that call attention or adds interest to a particular
object or usual feature of interest in a room. Highlight
emphasizes illumination with a strong light; backlight
illuminates from behind in order to embrace depth or to
separate the object from the background.

17. Most commonly seen in branded retail shops.
Can be achieved by several ways by using
different types of lanterns.

18. Candlelight and firelight is also a part of natural light. The
quality of sunlight will depend on the time of the day and the
season within the year. Where as candlelight/firelight is the
light that moveable.

20. A lamp designed to project or diffuse a comparatively uniform
level of illumination over a large area.

21. The main purpose of the street
light is to provide adequate
illumination of the street and its
surrounding to the driver point
of view.

23. Spotlights are most commonly used in
concerts, musicals and large scale
presentations where highlighting a
specific mobile individual is critical.
Spotlights are sometimes located
overhead on catwalks.

25. Lighting provide by adjustable spotlights mounted a long
narrow, ceiling-or-wall-mounted metal track through which
currents is conducted.

26. Light strip is now a day most commonly used to illuminate sign
boards by applying on the corner of it.

27. A luminaire having a trough-shaped reflector holding one or
more fluorescent lamps.

28. A lighting fixture suspended from a ceiling or wall by a flexible
cord, by which it can be released or lowered.

31. Most lamps direct light
downward, with the exception
of a torchiere, which is a floor
map that directs its light
upward.
Lamps are often used as task
lights, particularly for reading,
but can also provide ambient
light.
