For those beginning photography, exposure is key to capturing a great image.
Learning how exposure works will help you to take control of your camera and take better photos. Aperture, shutter speed, ISO are the elements that combine to create an exposure.
As you’ll soon learn, these elements have an effect on more than just the exposure. They also cause alterations in depth of field, motion blur, and digital noise.
Once you understand how each one works, you can start diving into manual mode. This is where you take control back from your camera.
The exposure triangle is a great way to remember the three settings. When combined, they control the amount of light captured from any given scene.
This will help you to understand that changing one setting will necessitate a change in the others. That is if you are photographing the same scene with the same exact lighting conditions.
Read here for all the information you need on the exposure triangle.
Exposure happens in three steps. We will start with the aperture. This is the hole inside the lens, through which the light passes.
It’s similar to the pupil of your eye: the wider the aperture, the more light is allowed in and vice versa. Simple? Not quite.
As the aperture widens, the f/number gets lower and more light is allowed into the camera. This is great for low light but be aware that it’s going to make the depth of field very shallow – not ideal when taking landscapes.
So there’s a bit of give and take and I go into full detail about that in this post. The aperture is the preferred setting to set first, as it directly influences how much of your scene is in focus. But, if you are looking to create motion blur, then it is second to the shutter speed.
Exposure will be much easier if you can memorize the f/stop scale.
The scale is as follows: f/1.4, f/2, f/2.8, f/4, f/5.6, f/8, f/11, f/16, f/22.
Once the light has passed through the aperture of the lens, it reaches the shutter. Now you need to decide how much of that light you’re going to allow into the camera.
Ordinarily, you only want a very small fraction of a second (for example 1/250) to prevent motion blur. However, different shutter speeds complement different situations.
Anything from really fast (1/4000) for sports photography to really slow (30 seconds) for night photography. It all depends on what you’re shooting and how much light you have available to you.
Knowing how your shutter speed works is a key element in the basics of photography.
Once the light has passed through the aperture and been filtered by the shutter speed, it reaches the sensor. This is where we decide how to set the ISO.
As you turn the ISO number up, you increase the exposure. But, at the same time, the image quality decreases. There will be more digital noise or “grain”.
So you have to decide upon your priorities in terms of exposure vs grain.
For example, I would reduce the image quality if it meant that I could prevent motion blur in my photo. There’s no possible way to fix that in post-production (yet, at least).
Once you’ve understood aperture, shutter speed and ISO, you need to learn how each of these elements of exposure work together.
For all those basics of photography, exposure is the most important.
If you don’t have this down, composition and framing become a moot point in beginner photography.
In this post, you will learn about the ‘stop’ based system for measuring exposure. But, more importantly, how to prioritize the aperture, shutter speed, and ISO for the best photo.
Understanding Your Camera
Digital photography for beginners can be confusing. Exposure isn’t as simple as learning about aperture, shutter speed, and ISO. You also have to learn about how your camera looks at light.
Metering modes are there to tell your camera how you want it to look at a scene.
The photo below was taken on spot metering mode but, if you were to take the same photo using evaluative mode, you would end up with a completely different exposure.
This is also covered in my free video training. If you’re looking for an article that explains digital, including Canon, metering modes, here it is.
Understanding this basic photography point may just be the key to understanding why your photos are coming out underexposed or overexposed.
The histogram shows you a mathematical review of an exposure after the photo has been taken. It essentially tells you how evenly exposed a photo is.
LCD screens aren’t very good at showing you this information through their display of the image. This is because they are affected by the ambient lighting conditions you’re in and the brightness of the screen itself.
That’s why the histogram is such a powerful tool to utilize in beginning photography correctly.
Full-Auto, Program, Aperture Priority, Shutter Speed Priority or Manual Mode. How do you work out which one you should be using?
There’s also a lot of misconceptions about which mode to use under which conditions. On top of a lot of bias towards not using manual mode.
When you understand what exactly each mode does, the one that will be suitable for your situation becomes a lot clearer. This is also covered in my free video training.
When you’re shooting in low light, you invariably have to widen your aperture to allow enough light into the lens. But this has one rather a major side effect. A shallow depth of field.
This can be used very creatively (often to excess) but it’s not the only possibility. There are many situations, such as landscapes, where you’ll want to be using a narrower aperture so that the whole scene remains in focus.
This tutorial walks you through everything you need to know about choosing the right aperture (and therefore the depth of field) for the right situation.
When it comes to covering all of the basics of photography, depth of field is very important.
White balance is something I wish I’d learned more about much sooner than I did. I look back on some photos now and wonder what I was thinking.
The white balance changes the color cast of the entire photo. It is responsible for the overall warmth. It can determine whether your photo appears blue or orange, cold or warm.
Auto white balance doesn’t tend to do a particularly good job, particularly with tungsten light. The sooner you learn about this basic photography idea, the more accurate your photos will look.
This is also covered in my free video training.
Have you ever wondered what the ‘mm’ on your lens actually means? Or why people use longer focal lengths for portraits?
It’s all discussed in this tutorial. The focal length affects more than just the ‘zoom’. It also influences the perspective.
I cover which focal length you would want to use in different situations. As well as their possible side effects.
It’s a really worthy read and one of my favorite tutorials to date.
A lot of you may not realize but, unless you spend about $2000 on your camera, you’re more than likely to be shooting on a crop sensor.
This means that your sensor is much smaller than professional SLR cameras, essentially cropping your image. The crop factor has a range of effects on your photos.
It creates a narrower viewing angle and will influence your lens purchases in the future. For those beginner photographers, research what lenses will help your field of photography first.
Polarizing filters only allow light into the lens from a certain direction. This results in the removal of glare and reflections from non-metallic objects.
Water and glass are the most affected, as well as haze from the sky. Cutting out these reflections and anomalies will make for more naturally saturated colors.
Not only does this look great but it cannot be replicated in post-production, hence it’s so important to understand.
For beginning photography, I will walk you through the 10 step process of taking professionally sharp photos.
It covers everything from choosing the right aperture and shutter speed to shooting in RAW.
It’s pretty easy to make just a few small mistakes which will result in less sharp images. That’s why we cover all ten, in order of importance.
What can I say about the nifty fifty? What’s not to love?
For those of you who are beginner photographers, when I talk about the nifty fifty, I’m referring to the 50mm f/1.8 prime lens. This can be picked up very cheap for most digital SLRs.
It’s a great introduction to buying better quality lenses and an excellent way of getting to grips with aperture.
The article linked is a review and guide. I wrote it because I recommend this lens as the first upgrade for every beginner photographer to make.
It’s easy to use and, for the price, will yield some excellent results.
It’s important to understand exposure. But, if you can’t get to grips with basic composition, you’ll struggle to take really good photos.
I’m not saying that you have to follow every compositional rule. But it helps to learn these rules so they can help guide you in taking better photos.
This is probably the first compositional rule that any beginner photographer comes across. And that’s for a very good reason: it’s simple and it works.
The basic premise is that you divide your camera’s frame into thirds. By planting key objects on these lines, the composition of the image works better.
This is a tool that consistently works, but it is easy to overuse it. If you’ve not learned much about photography yet, it’s a great way of dramatically improving your photos.
It will help to make them more interesting.
Visual weight differs in size or weight as we know it. It’s all about what we’re drawn to when we look at a photo.
When you understand visual weight, you’ll start to understand how people look at photos and how you can position certain elements in a frame to direct the viewer’s attention to where you want them to look.
It’s not so much a tool or a rule, but an understanding.
Shapes are very important in Photography. Triangles are in almost everything we see in one way or another, it’s just a case of distinguishing and knowing what to do with them.
Triangles make great compositional tools as they’re easy to make and manipulate, and are remarkably common. These are a great way to use the simplest and most basic photography compositions.
They are also perfect for combining different compositional techniques. These include lines and paths, to create a more interesting part of a photograph.
You can even use them to make a photo feel more stable or unstable.
If you take photos of people, you’re taking photos with eye lines. It’s important to understand the effect that eye lines have on how we view a photo.
Eye-lines are the direction your subject’s eyes are pointed in. The negative space in front of the subject’s face is known as ‘lead room‘.
These have the ability to focus our attention on a particular part of the photo. They also produce tension and other photographic elements.
Although they’re not physical lines, they can be used as such to produce different elements. These will help make triangles and vertical lines.
Balance in a photo affects how we feel when we look at it. An unbalanced photo can make us feel uneasy, whereas a balanced photo will make us feel more relaxed.
It really doesn’t matter whether you choose to make the photo balanced or unbalanced. But you should understand why you’ve chosen one or the other.
Both affect your photos in different ways.
Again, it’s one of those situations where the more you know, the easier it will be to produce the desired effect.
