Basic photography

When we take photos in manual mode,camera gives us a lot room to adjust by ourselves. Aperture,shutter speed and ISO are three major elements,we don't change ISO too much,because we like sharp,high resolution pictures always.

Here is a quick example of different ISO setting in same object. 

Aperture is like a pupil of camera, the number of it stands for  distance to edge of the lens, therefore, the smaller number is the wider it open, vice versa.The aperture not only decide how much amount light come into camera, but also influence the depth you want between a main object and background in your photo.

Following pictures illustrate how aperture works. 

                                       

 Besides, shutter speed is another interesting component of taking a photo. The picture under show us that slower shutter speed can capture more than one frame of the movements,which means special blurry effects of sports,lights and so on can be achieved.

 The basic third rule also need to be taken in to consideration when we think about composing the picture, that will upgrade the quality of photos.
