Basics of photography (Part -3)...
"As most of us live in a world of democracy, this means that almost every country has its own democracy. Democracy now operates on its four pillars (legislature, executive, judiciary, media), just as photography operates on three pillars (hole, hole, shutter-speed, ISO). Now, as a photographer, it's your job to master these three basics, because photography works on these three basics."
(NOTE: If you are new to this blog, then before reading this article, do check the previous articles.)
In the previous articles of this series, we have discussed the following things, do check them out :
So, let's discuss the three main pillars of photography in detail, they are as follows:
1) APERTURE :
The hole is the most important column than the other two because it adds different dimensions to your images by focusing on the subject and obscuring the background or foreground, the first thing being. Another thing is that it can bring the whole image into focus. So basically it controls the depth of field.
Now, depth of field is nothing but how much image is in focus is the depth of field of that image. Now consider that a hole is a hole made in a lens that controls the amount of light entering the camera. The bigger the whole, the more light is entering. Small means full, low access.
Now, how is this hole expressed? Hence it is expressed in terms of 'f-stops or f-numbers'. F-stops are numbers that tell you the full diameter. 'Small means hole, big means whole and big means hole, small means whole'. If you increase the F-stops, it means you are reducing the hole (diameter of the hole) and vice versa.
Now, how is this hole expressed? Hence it is expressed in terms of 'f-stops or f-numbers'. F-stops are numbers that tell you the full diameter. 'Small means hole, big means whole and big means hole, small means whole'. If you increase the F-stops, it means you are reducing the hole (diameter of the hole) and vice versa.
2) SHUTTER SPEED :
Now, what is the first shutter? So imagine that your eyelid is the camera sensor and your eyelid is the shutter of your eye. So when your camera doesn't fly, your camera shutter is closed so that no light can come in and apply to the camera sensor. Exactly what happens when you press the shutter button, your shutter opens so the light comes in and hits the camera sensor and after the sensor enters the light and captures all the details, the shutter closes and the image is captured.
Now, shutter speed is how long the shutter is opened to collect information through the light. So by adjusting the shutter speed, you are basically adjusting how long your shutter will open.
Now how is this shutter speed expressed? So it is expressed in seconds, mostly in seconds. Such as - 10sec, 5sec, 1sec, etc; in seconds and 1 / 2sec, 1 / 100sec, 1 / 1000sec, etc. Now, what is 1/100sec, which means 1/100th of a second. '1/10 seconds <10 seconds'.
3) ISO :
ISO is a very important pillar of photography, as it will control the quality of your image. But now what does this ISO mean? ISO is nothing but the sensitivity of your camera's image sensor.
Now what does this sensitivity mean? Sensitivity basically controls the amount of light required. For example, if the sensitivity of the sensor is low, the amount of light required is high and if the sensitivity of the sensor is high, the amount of light required is low. And this sensitivity is controlled by ISO.
Now how is this ISO expressed / represented? In our cameras, it is basically represented by numbers. Such as - 100, 200, 400, 800, etc. So now ISO is the complete opposite of the hole, here as you increase the number you increase the ISO (sensitivity) and the amount of light required is less. As you reduce the number, you are reducing the ISO (sensitivity) and the amount of light required will be higher.
