Starting photography as a student is exciting, but it can also be confusing. Aperture, shutter speed, ISO, and exposure are just some of the terms banded about, which make it easy to feel lost when you’re a beginner. That’s why we’ve created this step by step guide, which is packed with tips and tricks to help you understand how a camera works, and how to take better photos.
This is one of our student-focused articles, which cover the essentials of photography and content creation, explaining some of the common jargon that you come across all of the time. If you’re just getting into cameras you might also want to check out our student guide to camera equipment, which covers the different types of cameras, sensors, and lens terms in photography.
In this guide we focus on how photography works so you’ll get an understanding of the key ingredients, including aperture and shutter speed so you can improve your skills more quickly.
So let’s begin with the first feature you’ll need to understand…
Aperture is one of the first things to get to grips with when learning how to use a camera. It refers to the opening inside the lens that controls how much light reaches the sensor, or film if you’re shooting analogue. You’ll see aperture shown as f-numbers (like f/2.8, f/5.6, f/11), and while it might seem backwards at first, the smaller the f-number, the wider the aperture.
A wide aperture like f/1.8 lets in more light and creates a shallow depth of field, which means only a small part of the image is in focus, which is ideal for portraits with a blurry background to draw attention to the subject. A narrow aperture like f/16 lets in less light and gives you more depth of field, keeping more of the scene in focus, which is more useful for landscapes and that type of subject.
You don’t need to memorise the aperture scale straight away, but it helps to know that each step (f/2.8 to f/4, or f/8 to f/11) lets in half as much light as the one before it. Once you’ve got the hang of that, you’ll start to see how aperture affects both brightness and focus in your photos.
Next, we’ll look at how shutter speed works with aperture to control exposure and motion.
Shutter speed controls how long your camera’s shutter stays open when you take a photo. A fast shutter speed (like 1/1000s) freezes action, which is great for sports, wildlife or any fast moving action. A slower shutter speed (like 1/30s or even 1 second) lets in more light, but can blur movement. Slow shutter speeds can be used creatively, or you can avoid it by shooting from a tripod.
You’ll usually see shutter speeds shown in fractions of a second, such as 1/200, 1/60, 1/4, or in whole seconds when you get into long exposures. Just like aperture, each step doubles or halves the amount of light coming in, so 1/125s lets in twice as much light as 1/250s for example.
For handheld shooting try to keep your shutter speed equal to or even a bit faster than your focal length. For example, use 1/50s or a little faster with a 50mm lens to avoid any camera shake. In-body image stabilisation can help reduce shake, but it’s still good practice to be aware of your shutter speed, especially if using a high resolution digital camera.
Examples of using shutter speed creatively include when you want to freeze a splash of water, or if you want to show movement in waterfalls or light trails at night, then shoot much slower from a tripod.
It’s worth experimenting with shutter speed to see how it affects different subjects, so try a few speeds out for each shot until you discover the speeds, which you most like for a given situation.
Now that we’ve covered aperture and shutter speed, let’s look at some other photography terms that are useful to understand when starting out.
Once you start learning photography, you’ll quickly notice there’s a lot of terminology, and while some of it is useful, some may be confusing at first. You don’t need to memorise every technical term straight away, but it can really help to get familiar with the ones you hear most often in college, on YouTube, or when chatting with other hobbyists.
Here are a few of the most common photography terms:
There are lots more terms worth knowing as you progress, and we’ve covered a more comprehensive list in our Photography Terms Explained guide if you want to dive deeper. In the meantime let’s look at some of the basics you need to know when starting out on your photography journey.
Once you understand the basics of how your camera works, the next step is to get out and start using it! The best way to improve is with practice, not by owning the most expensive gear. Here are five tips to help build confidence and start enjoying photography from day one:
For more tips on building your skills and avoiding common beginner mistakes, check out our Best Photography Tips for Beginners article, which goes into more detail.
Learning photography as a student doesn’t have to feel complicated. With a bit of time and regular practice you’ll start to understand how aperture, shutter speed and ISO work together, which will lead to taking photos that you’re proud of.
When you’re ready to pick up your first camera or lens, our used photography equipment section is packed with budget-friendly options, which have all been checked and tested by our specialist team. Whether shooting for a college project or just for fun, you’ll find the right gear to get started, and grow your skills from there.
