What is Photography? Unveiling the Art of Photography through the Lens

We’re going to learn about the art and science behind capturing images in this article. Discover what photography really is and how you can take professional photos.

What is photography?

Photography is a process involving capturing light rays on a recording medium that’s sensitive to light. When you combine film or a digital CCD with those light rays, they create visuals that we can see. It has two categories:

The science of setting:

This part focuses on the technical side of things, and there’s not one photographer out there who doesn’t need this part. It’s all about finding the perfect balance between your camera and recording media so pictures come out as well as possible.


Eye-catching photographs aren’t created through chance or luck. They are made by people who have mastered the art of creativity when it comes to photography.

Traditional methods used film to record media back then, which included chemical procedures.
Digital photos dominate contemporary times, though, but don’t worry; you still need to know how both types work at a fundamental level.

When using a camera, you’ll always find yourself looking through a lens, which is an optical element.

Its main job is to focus incoming light rays so they produce sharp images on whatever recording medium there is. The lens does more than sharpen images; it also determines how much light gets bent. Understanding lenses is half the battle in understanding photography.

Just like any other art, photography needs practice. And knowing your camera well and your photo composition

Here are the three main things you have to learn:

1. Shutter Speed
2. Aperture
3. Iso  

Shutter Speed

The speed at which the shutter opens and then closes is known as the shutter speed. This is measured in seconds or fractions of it (1 s, 1/2 s, 1/250 s, 1/500 s, 1/800 s, and so on). How long your image sensor is exposed to light depends on how long you set the shutter speed. The faster the shutter speed, the shorter the image sensor is exposed to light; the slower the shutter speed, the longer the image sensor is exposed to light.

Different effects can be seen when capturing something that’s moving at different speeds on the shutter. Slow ones bring out two types of blur: subject movement and camera shack. On the other hand, a fast shutter speed makes your subject freeze in place. The harder it is to capture a subject without making them blurry and freeze motion, this camera shake becomes less noticeable.

Slower shutter speeds, on the other hand, are more suited to imply motion, such as that of moving objects or flowing water. If you want to “freeze” or suggest motion, you may manipulate this by adjusting the shutter speed.

Fractions are used to represent speeds greater than one second, such as 1/125, 1/250, 1/400, and 1/800. Some cameras omit the numerator, resulting in “1/400” becoming “400,” “1/250” being “250,” etc. When the speed is less than one second, a double prime symbol is added to the value, such as 1.6″.


Aperture is the most crucial of the three photographic fundamentals, the others being shutter speed and ISO.

What is aperture?

The opening in a lens through which light enters the camera is known as an aperture. If you merely consider how your eyes function, the concept is simple to grasp. The size of your pupil is controlled by the iris in your eyes, which expands or contracts when you travel between bright and dark situations.

The “pupil” of your lens is referred to as the aperture in photography. To allow more or less light to reach your camera sensor, you can increase or decrease the size of the aperture. The nine blades create a diaphragm to stop all light except that which passes through the center from passing.

How Aperture Affects Depth of Field

The depth of field is an important aspect of the aperture. Your image can gain dimension by using the aperture to adjust the depth of field. Aperture can create a lovely shallow-focus effect with a blurred background. On the other hand, you can get a sharp image from the nearby foreground to the far-off horizon.

The amount of your photo that is sharp from front to back is known as the depth of field. In some pictures, the background is totally out of focus due to a “thin” or “shallow” depth of field (referred to as bokeh). Other photographs feature a “large” or “deep” depth of field, in which the background and foreground are sharply defined.

Always remember that the choice of aperture is crucial. To get a shallow focus impression, use a wide aperture. This will assist you in diverting the viewer’s attention away from the crowded background and toward the subject. You would not be able to successfully isolate your subject from the background if you selected a much lower aperture, like f11.

There is a simple way to remember this relationship: a large aperture causes a lot of blur in the front and background. When you wish to isolate the subject of a portrait or generic photograph of an object, this is frequently beneficial. The foreground objects you use to frame your subject sometimes appear blurry in relation to the subject.

A small aperture, on the other hand, produces a small amount of background blur, which is often suitable for some photography, like landscape and architectural photography.

How Aperture Affects Exposure

Your image exposure, or brightness, is one of the most crucial factors. The brightness of your image changes as a result of changes in the overall amount of light that enters your camera sensor.

An image will be brighter because a large aperture (wide opening) lets in more light. On the other hand, a tiny aperture results in a darker image.

You should usually choose a big aperture in low-light conditions, such as indoors or at night, to collect as much light as you can. This is also the cause of your pupil’s dilation as it becomes darker

What Are F-Stop and F-Number?

We have described Aperture so far only in broad terms, such as large and small. However, it can also be stated as an “f-number” or “f-stop”, which is a number with the letter “f” preceding it, such as f/4.

You have probably already seen this on your camera. Your aperture will appear like this on your LCD screen or viewfinder: f/1.8, f/4.5, f/11, and so on. Some cameras write the f-stops without the slash, such as f1.8, f4.5, f11, and so on.

Small vs. Large Aperture

Note This: Large numbers correspond to small apertures, while small numbers correspond to large apertures. For instance, f/2.0 is substantially larger than f/4 and f/11. Since we are used to larger numbers representing larger values, most people find this awkward. But this is a fundamental truth of photography.

Setting the Camera’s Aperture

There are two settings that work if you want to choose your camera’s aperture manually for a photo (which is something we highly encourage). These modes are aperture-priority mode and manual mode. On most cameras, manual mode is denoted by the letter “M,” while aperture-priority mode is denoted by “A” or “Av.” These are often located on your camera’s top dial. When shooting in aperture-priority mode, you choose the desired aperture, and the camera chooses the shutter speed for you.

Lenses’ Minimum and Maximum Aperture

The maximum size or minimum size of the aperture for each lens is fixed. The maximum and minimum apertures of your lens should be listed in the specifications on your lens denoted as 1:2.8G. The maximum aperture, which indicates how much light the lens can capture at its utmost (essentially, how dark of an area you can take shots in), will be the most significant for every lens.

A “fast” lens is one with a maximum aperture of f/0.8 or f/1.4 because it allows more light to pass through than, a “slow” lens with a maximum aperture of f/4.5. Large aperture lenses typically cost more.

The minimum aperture, in comparison, is less crucial because practically all contemporary lenses can offer at least f/16 as a minimum. For daily photography, you hardly ever need anything smaller than that.

As you zoom in and out with some zoom lenses, the maximum aperture may change. For instance, a large aperture like an f/3.5-5.6 AF-P lens steadily decreases from f/3.5 at the wide end to barely f/5.6 at the longer focal lengths. More expensive zoom Lenses like f/2.8, often maintain a fixed maximum aperture throughout their zoom range. Another advantage of prime lenses over zoom lenses is that they often have greater maximum apertures.

A lens’s maximum aperture is so crucial that it is mentioned in the name of the lens. When written with a colon rather than a slash, it conveys the same meaning as 1:1.7G.


When you choose a small aperture like f/32 you are likely to struggle with diffraction. Because you squeeze too much light that enters your lens. It ultimately causes interference with itself, blurriness, and considerably less sharp images.

Given how crucial aperture is, it shouldn’t come as a surprise that at Photography Life, we typically shoot in manual or aperture-priority mode. Almost never do we want the camera to choose the aperture for us. It’s just too crucial, and it’s one of those fundamental settings that any photographer beginner or expert needs to be aware of in order to capture the greatest pictures possible.


It’s always preferable if you practice more and more, Put your new skills to use by looking for something spectacular to photograph. You’ll learn more the more pictures you take.


1. What does manual mode mean and do I have to learn it?

Manual mode means that the camera gives you complete control over the exposure settings, allowing you to manually set the aperture and shutter speed to any value you like. This mode is typically employed when the camera struggles to determine the proper exposure under challenging lighting conditions and is the most recommended mode by professional photographers.

2. What are the 3 most important things in photography?

These are the three most important things in photography

*Technical part of photography

* Creative part of photography

*  Photography composition

3. What are the elements of a good photo?

Sometimes it’s good to pull back from larger conversations on creativity to focus on the composition’s most basic components. This can be categorized into two primary groups: objects and their connections. These are the fundamental components of creativity. These are Points, shapes, lines, texture, colors, tones, distance, balance, Space, and Patterns. Despite the fact that there are more than 10 elements of composition, these are the ones that photographers should be most familiar with.
