Playing with Exposure

By:Chandramouli Singh BJ&MC-2D

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

Exposure

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.

Things necessary for long exposure photography:SLR/DSLR CameraTripodGood CompositionRemote for shutter release (in some

special cases)

How To ??

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

photography.

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.

Surreal Landscapes

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.

Light Painting

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

Traffic Trails

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.

Star Trails

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.

Star Trails

Also called deep sky imagingIn 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
