We thought of bringing something grand for all the beginners and amateurs of photography out there. An article that can make an amateur know about the prime elements of photography and stuff inside his camera, paving way for his/her growth as a Photographer. It’s going to be a nightmare for any beginner to scroll around the priority modes with his DSLR, this article should get you fixed and should make you a pro in instance.
To begin with, all these three elements are important for making a picture, its more or less a combination of these 3 workings on an equal basis. But at times, we need to prioritize things, when we want to shoot a specific kind of a picture. That’s when all these priority options come into play. So before we jump into looking into these Priority options lets figure out what these terms actually mean.
Everything about Aperture, Shutter Speed and Exposure

Aperture is a hole or opening for the light to travel through it. In simple terms, Bigger the hole maximum the light flow. The aperture is also responsible for the sharpness of the image relative to the quantity of light admitted inside. Resulting in a sharper image with very shallow defocus and then there is the aperture stop which is responsible for determining the ray cone angle responsible to the bright spot. Aperture is measured in terms of f/stops. Starting from the brightest and going to the dimmest they could be anywhere between f/1 to f/22.
Now we know, what aperture stop does and this aperture stop is very important in determining the depth of field of an image. In combination with the alterations of shutter speed and exposure, we can regulate light into the sensor and so on.
A lens with a larger aperture is often called a Prime lens or fixed focal length lenses. They are very fast lenses that allow more light compared to the zoom lenses. So when you shoot in aperture priority more often when you use prime lenses, when you don’t want to care about your shutter speed, and you can still adjust your exposure on the go.

#2 Shutter Speed
The time given by you to the camera sensor for the amount of light for it to receive is called the Shutter Speed. In other words, the shutter speed is equal to the time the shutter remains open to click a picture. Faster shutter speed can freeze a moving object whereas a slow shutter speed can bring blur to your picture. Now let’s forget about aperture, logically lesser the shutter speed maximum the light entry into the sensor. Those fast action freezes or those blurry action shots are all due to shutter speed. Here there is no context to the aperture but again a combination with aperture can give you great results.
Imagine a huge tiger freezed while jumping over a deer with a great defocus background. This is where both aperture and shutter speed bond together and create magic. Also one should play safe with faster shutter speed since there is a high chance for the image to get underexposed.
Aside from the shutter speed, photographers should also think of the shutter count.
What the right one is depends on the camera type. Most entry to mid-range cameras have a 100,000 to 200,000 shutter count rating. On the other hand, professional-grade cameras have 400,000 to 500,000.
For many professional photographers, the shutter count makes up a huge part of a camera’s lifespan and value. It’s also an indication of how the user cares for the device.
A camera’s shutter wears out every time it’s opened and closed. Eventually, it will need replacement.
Furthermore, the camera’s internal memory stores the shutter count rating. Once your camera reaches its shutter count limit, the image quality diminishes.
Many photographers attempt to reset the shutter count using firmware. But this task requires some tech skills. You can determine how much your DSLR has left with a camera shutter count app.

OK. Now let’s speak about Exposure.
Exposure is the total amount of light allowed to enter the sensor, which is measured in terms of lux. Knowing how to manipulate this is a huge part of good photography.
Exposure is influenced by shutter speed, aperture, and the camera sensor’s light sensitivity. Adjusting these settings well can make a sunlit scene look moody or a dark room look bright. Most DSLR cameras are equipped with automatic exposure systems which automatically produce shots of optimal brightness.
Again exposure is solely dependent on shutter speed or aperture, even the physical formula says so.
- Exposure = Ev . t
- Hv is the luminous exposure (usually in lux seconds)
- Ev is the image-plane illuminance (usually in lux)
- t is the exposure time (in seconds)
At times every one of us click some burnt-out darks or the bleached out whites, which technically are called as underexposed or overexposed images.
So how do we know if an image is properly exposed, well watch out this section for some articles on zone system and its role in Photography.
