How to Take Beautiful Pictures in Your Own Backyard
You don’t have to travel to an exotic locale or take hours to find the right picture. You can take beautiful pictures right now in your own backyard.

Exposure is how much light there is in your image. Exposure is determined by three settings: aperture, shutter speed, and ISO. Properly exposing your images will get you more detail and stronger color. You need to understand these elements to consistently take good pictures on purpose.
For a visual representation of how the three exposure settings work, see the exposure triangle below.
Next, we’ll go over a quick written refresher of Aperture, Shutter Speed, and ISO.
Aperture refers to a hole inside a camera lens that opens and closes letting in more or less light. Aperture controls two things: Depth of field and exposure.
A higher aperture such as f/16 lets in less light and has a wide depth of field (everything in focus).
A lower aperture such as f/1.4 lets in more light and has a shallow depth of field (very little in focus).
A shutter is an object that sits in front of the camera sensor and allows light to reach the sensor for a predetermined amount of time. That predetermined amount of time is called shutter speed. Shutter speed affects two things: Motion blur and exposure.
A faster shutter speed such as 1/1000s lets in less light and has almost no motion blur.
A slower shutter speed such as 1/2s lets in more light and has lots of motion blur.
ISO is not really a part of exposure, because it does not affect how much light reaches the sensor (the definition of exposure). It kind of is though, because it affects how bright or dark the final image looks.
What is ISO? In modern digital cameras, ISO is the amount of amplification that is applied to the light entering the sensor. ISO affects two things: Noise and exposure.
A low ISO such as 200 results in a darker image and almost no noise.
A high ISO such as 12800 results in a brighter image and lots of noise.
You understand the settings, but how do you know what the exposure will look like before you take the photo?
Modern digital cameras give you the option to view the exposure your camera thinks your photo will have based on your chosen settings. This is shown on the back-LCD monitor. You can see this by turning on the “live exposure view” setting. For Canon DSLR cameras, this is turned on by pressing the “live view” button on the back of the camera. Check your manual to see how to turn live view on for your camera.
The “Zebra Pattern” setting is a great addition to live view. With this turned on, overexposed areas will be covered with moving black and white stripes on the back-LCD screen. Not all cameras have this setting and they may be called different things based on your brand of camera.
Another way you can check exposure before taking a photo is the histogram. Once turned on in your camera’s settings, you can see the histogram on your back-LCD screen. It’s only visible when in live view mode. The histogram gives you detailed information about how your image is exposed.
Histograms tells you how many pixels in your image have a certain brightness or tone. A tonally balanced image will have a shape like the one below with lots of mid tones, some light, and some dark tones. If the shape of the histogram is skewed to the left, the image is composed of lots of dark tones and is likely underexposed. If the shape is skewed to the right, there are lots of light tones and the image is likely overexposed.
The histogram is more accurate than live exposure view for the exposure of the whole image, but live exposure view may be helpful for making sure a specific part of the image is exposed correctly. Use the histogram to check the exposure and balance of your image together with the live exposure view for the best exposure results.
You now know what all the settings do and how different exposure modes work, but you may be asking yourself “How do I actually properly expose an image?”. A valid question. There’s a difference between knowing what every setting is and knowing what to do with them. To answer that question, I’ll go into some exposure guidelines for popular types of photography.
Cameras have a few different ways that these exposure settings can be chosen. These ways are called exposure modes. Exposure modes are made to make certain types of photography easier by automatically setting some, or all exposure settings.
The ones you need to know are: Auto, Aperture Priority, Shutter Priority, Manual, and Bulb. The letter or symbol for each given mode is different based on the brand of camera. Check your manual to see what it is for your camera. The graphic below shows the basics of each mode.
Let’s go a little deeper on these modes. When the camera chooses a setting itself, it does it through metering. Metering is basically a sensor inside the camera that decides what the correct exposure is based on what it sees. The sensor can be confused and is not always right.
In my opinion, this should only be used if you don’t know a picture is coming and have no time to set the settings yourself. You give up creative freedom with depth of field and don’t get to use exposure creatively. You also have no control over noise.
This setting is great if you want control over depth of field and noise, but don’t want to deal with finding the correct brightness. The downside is metering isn’t perfect and leaves no room for creativity or personal preference. This mode may also choose a shutter speed that is too long for being handheld resulting in a blurry image.
If you need control over shutter speed and don’t care about depth of field or noise, this is the mode for you. This mode is useful if photographing a moving subject where you need control over shutter speed to get a sharp image, but there isn’t time to change other settings. This scenario should be rare.
You should almost always be on manual mode. This mode gives you control over all three aspects of exposure, giving you the most control over your final product. As you become better acquainted with aperture, shutter speed, and ISO, controlling all three settings not only feels easy, but necessary to get exactly what you want from a photo.
This mode should be used when you want a shutter speed longer than what your camera normally allows (usually 30s). Bulb is like manual in that you choose all three settings, but shutter speed is determined either by a second press of the shutter button, or a remote shutter switch.
