2.  It is the amount of light entering the camera that is
received by a photographic film or an image
sensor.
 Exposure is mainly determined by two things:
 Shutter Speed: Speed of shutter opening to expose
sensor or film to the light.
 Aperture: An opening that controls the amount of light

3.  There are many ways in which we can play
around with exposure to get some surreal,
out of the world photographs.
 Long exposure is used by photographers to
click such photos.

4.  Things necessary for long exposure photography:
 SLR/DSLR Camera
 Tripod
 Good Composition
 Remote for shutter release (in some special
cases)

5. Coming in the next slides are the various
types of shots that are taken through
long exposure photography.

6.  This type of photographs contain either water or
moving clouds.
 Exposure of around 10-30 seconds, depending
upon the situation gives the smooth texture to
water and sky.

10.  This is another fancy photographic technique in which
painting with light is done.
 Camera is set on tripod at a completely dark place with
minimum aperture and long shutter speed of around
20-30 seconds.
 Then, after the shutter is released, using any point
source of light one can perform tricks, draw something
etc.

14.  This is most common usage of long exposure
photography where camera captures the moving
lights coming from vehicles on the road.

18.  This is perhaps one of the most difficult things to
do in long exposure photography and requires a lot
of patience.
 The rotation of earth makes us feel that sun,
moon, stars and other planets move.
 We can capture their motion through this
technique.
 For taking star trails we need an automatic shutter
release remote.

19.  We set the shutter speed to 30 seconds and then
just take pictures one after another for minimum
of half an hour. People also do for more longer
time to get better results
 Then comes the editing part, on some image
editing software like Adobe Photoshop, all these
images are superimposed and edited to get the
desired image.

23.  Also called deep sky imaging
 In this, photos of distant stars and planets are
taken through normal DSLRs using long exposure
 Though it does not need much of extra equipment
but surely needs some knowledge of astronomy
