I have seen most of people seen capturing some interesting things. They keep just clicking the scenes, materials, portraits, etc. The reason is that today's mobile phones are having inbuilt digital camera. But these mobile camera has not much functionalities compared to the digital camera. We can capture the moments without learning anything, but we can capture MORE with some learning of digital photography.
The word digital photography says the image clicked will be stored in digital form. The scene infront of camera lens is a collection of colors in its pattern. The camera has the sensor to recognize the color. The sensor has pixels which store 1 dot of color. These collection of pixels create the whole image and store it to storage, i.e. memory card.
The digital camera doesn't just record colors which is infront of lens, but today's cameras having a large number of functionalities. We can create a stunning images of just simple things if we can understand and use properly these functionalities. I am going to show you some basic but important functionalities of digital cameras.
EXPOSURE
At night, when you are going to sleep, you turn all the lights off. At that time you are not able to see anything in room. After just 15-20 minutes, you feel that more you can see.
The camera sensor is the light collector. If the scene is under-light(low light), you can collect more light with extending exposure. Generally the exposure is measured in seconds. So 2sec exposure will be brighter than 1sec exposure. For daylight, exposures range from 1/100 to 1/2000. Exposure is also known as shutter speed. Slower the shutter speed means longer the exposure.
Extending the exposure is not always good idea. When you want to capture moving things, like bike, car, bird etc, the slower shutter speed will cause motion blur in resulting image.
F VALUE
It is also known as aperture. Aperture is the open area of lens during clik. Lower the aperture, less light will enter into camera. So image will be darker. But the benefit of smaller aperture is it will make image more sharp. The term depth of field comes to the picture.
Consider, if you capturing a friend's portrait having a tree in background. If you keep wide aperture as f/3.5 and your friend is on focus, the background tree will be blured. Now if you set aperture as f/16, the tree will be less blured. In f/16 the image will be darker, that can be managed by setting exposure or ISO values.
ISO
It the standard values of light sensitivity. More the ISO value, more the light will be sensed, and resulting image will be brighter. In daytime, generally iso100 is enough. I use iso800 and iso1600 for capturing astronomical images. One drawback of iso is that, more iso gives more noise. So iso1600 will give a huge amount of noise.
