What is the Exposure Triangle ???

We can control the Exposure with these three elements .

1-ISO       2- Aperture   3- SHUTTER SPEED

ISO – Measure the sensitivity of digital camera to the light . So what does sensitivity mean?  low sensitivity means that the sensor has to be exposed to light for a longer period of time than a sensor with a high sensitivity in order to properly expose the image. it is always a better idea to go with low sensitivity or low number of ISO. as you crank up the ISO level the chances are more that you are introducing noise to your image .

Aperture – The size of the opening in the ires of the lens. Aperture is the hole within a lens the more you open the hole the more light travels into the camera body, it is easier to understand the concept if you think about our eyes. our eyes works same. The pupil is refer to as aperture in photography. The amount of light that enters the retina which works just like the camera sensor
Note: When we change the aperture we change the dept of field as well it is better to keep that in mind.Aperture is measured using F-stops
the size of circles defines the size of the lens aperture the larger the f-number, the smaller the aperture.

SHUTTERSPEED – is the amount of time that the shutters of the window are open. The longer you leave them open the more light comes in.and shutter speed also controls the amount of blur in image for example . with longer shutter speed you always need tripod or monopod to prevent from shake otherwise the image become shaky or blurred .

Time-laps photography

 

Time laps photography has become extremely popular over the past several years Time-lapse is where a camera takes a sequence of images of a subject with an interval of time between each image. The interval can be anything from less than a second to a day or more. the interesting thing is that you are able to shoot even at very long exposure. And another advantage is that you are able to render your final sequence at very high quality even more than 20K  .

Rule of thirds

The rule of thirds is a powerful compositional technique for making photos more interesting and dynamic . It can be applied to any subject to improve the composition and balance of your images.as you can see in our example.When framing your image, place your subject on one of the lines or intersections created by the thirds.Image

Multiple exposure

A multiple exposure , simply put, is the superimposition of two or more images on top of each other . In the days of film, this was achieved by taking one picture and then, without advancing the film strip, taking another picture right on top of it. Today even digital cameras allow you to shoot multiple exposures.

In order to click a double exposure all you have to do is turn the the multiple exposure feature on, and click two or more shots are allowed on your camera.

for A high-key double exposure with a human subject as in our example , the background of your first shot should be as close to with as possible . this can be done by shooting with the sky filling up the background . For the second shot we bumped up the exposure compensation and took a picture of leaves for this image.
