Camera Settings Explained for Beginners (Master Guide)

Stepping into the world of photography can be an exciting and rewarding journey.

As a beginner, it’s essential to gain a solid understanding of the basic camera settings to unlock your creative potential and capture stunning visuals.

To capture a perfect shot, photographers need to balance three core camera settings: aperture, ISO, and shutter speed.

These settings, often referred to as the exposure triangle, work in tandem to determine the overall brightness and exposure of your photographs.

Apart from exposure, aperture and shutter speed also impart creative effects.

By mastering these settings, you will develop the ability to fine-tune your images, achieving the desired look and mood.

This master guide aims to explain the most crucial camera settings for beginners, making it easier for you to grasp their importance and learn how to adjust them effectively.

In the following sections, we will delve deeper into the exposure triangle, explore additional camera settings such as exposure compensation, and provide practical tips for applying these settings in various photography scenarios.

The Exposure Triangle

What are the 3 basic camera settings?

The Exposure Triangle consists of three key elements: Aperture, Shutter Speed, and ISO.

These elements work together to control the amount of light that reaches the camera’s sensor, ultimately determining the exposure of a photo.


Aperture refers to the size of the opening in your camera’s lens through which light passes.

It is measured in f-stops, with lower f-numbers representing larger openings and higher f-numbers representing smaller openings.

The aperture affects not only the amount of light that reaches the sensor but also the depth of field in your photo.

  • Larger aperture (lower f-number):
    • More light enters the camera.
    • Shallow depth of field (less of the scene in focus).
  • Smaller aperture (higher f-number):
    • Less light enters the camera.
    • Greater depth of field (more of the scene in focus).

Shutter Speed

Shutter speed is the amount of time the camera’s shutter is open and exposing the sensor to light.

It is typically measured in seconds or fractions of a second.

Faster shutter speeds help freeze motion, while slower speeds may result in motion blur.

  • Faster shutter speed:
    • Less light enters the camera.
    • Freezes motion in the scene.
  • Slower shutter speed:
    • More light enters the camera.
    • Can introduce motion blur if subjects are moving.


ISO represents your camera’s sensitivity to light.

A lower ISO value means the sensor is less sensitive to light, while a higher value means it is more sensitive.

Adjusting the ISO can help you achieve proper exposure in different lighting conditions.

However, increasing the ISO too much may result in noise or graininess in your photos.

  • Lower ISO:
    • Less sensitive to light.
    • Better image quality with less noise.
  • Higher ISO:
    • More sensitive to light.
    • Can result in more noise and grain in the image.

Focus and Depth of Field

What are the perfect camera settings?

Understanding Focus

Focus is the process of adjusting the camera lens to ensure that the subject appears sharp in the viewfinder and, subsequently, in the final image.

The primary element that influences focus is the aperture, which is the opening in the lens that controls the amount of light entering the camera.

Aperture is measured using f-stops, and a smaller f-stop number (e.g., f/1.8) represents a larger aperture and vice versa.

Depth of field (DOF) refers to the distance between the closest and farthest objects in a photo that appear acceptably sharp.

The main factors that affect DOF are aperture, focal length, and the distance between the camera and the subject.

A larger aperture (smaller f-number) results in a shallower depth of field, whereas a smaller aperture (larger f-number) results in a deeper depth of field.

Focus Modes

There are several focus modes to choose from, depending on your camera and the subject you’re photographing:

  1. Single-shot AF (AutoFocus) or One-Shot AF: This mode is suitable for still subjects, such as landscapes or portraits. The camera focuses once when you press the shutter halfway, locks the focus, and maintains it until the shutter is fully pressed.
  2. Continuous AF (C-AF) or AI Servo: This mode is designed for moving subjects, such as sports or wildlife. The camera continuously adjusts the focus as the subject moves when you press the shutter halfway.
  3. Automatic AF (A-AF) or AI Focus AF: In this mode, the camera automatically switches between single-shot and continuous AF depending on the subject’s movement.
  4. Manual Focus (MF): As the name suggests, this mode allows you to manually focus the lens by turning the focus ring, giving you complete control over the focus.

Choosing a Focus Point

The focus point is the area in the frame where the camera will focus.

Most cameras allow you to select a specific focus point, giving you more control over composition and ensuring sharp focus on your desired subject.

To choose your focus point, follow these steps:

  1. Set your camera to an appropriate focus mode.
  2. Activate the focus point selection mode on your camera. This can usually be done by pressing a dedicated button or navigating the camera menu.
  3. Use the directional buttons or touch screen (if available) to select the desired focus point.
  4. Frame the subject so that it’s covered by the chosen focus point.
  5. Press the shutter button halfway to lock focus and then press it fully to take the photo.

Metering and Exposure Compensation

Metering Modes

Metering is the process by which your camera measures the light in a scene to determine the correct shutter speed, aperture, and ISO settings. This ensures that your photos have the right exposure, which is a balance between shadows, highlights, and mid-tones. There are typically three main metering modes in cameras:

  1. Matrix Metering (Nikon) / Evaluative Metering (Canon): This mode takes into account the entire scene and calculates the exposure based on a sophisticated algorithm. It’s suitable for general photography and works well in most situations.
  2. Center-Weighted Metering: Unlike matrix/evaluative metering, this mode focuses on the light in the center of the frame and gives less importance to the edges. It’s useful for portraits or when your subject is in the middle of the frame.
  3. Spot Metering: This mode considers only a small area (usually a circle) in the center of the frame to measure light. This precise metering can be helpful for high-contrast lighting situations or when you need to expose for a specific part of the image.

Exposure Compensation

Exposure compensation is a feature that allows you to adjust the brightness of your photos manually.

To use exposure compensation, look for a button or dial (usually labeled with a +/- symbol) on your camera.

Here’s how to adjust exposure compensation:

  • To make your photo brighter, increase the exposure compensation (for example, +1 or +2).
  • To make your photo darker, decrease the exposure compensation (for example, -1 or -2).


  • Exposure compensation doesn’t work in Manual mode, as you control the exposure settings directly in this mode.
  • Be aware of your camera’s sensor limitations. Overexposing or underexposing your images may result in loss of detail in highlights and shadows.

Shooting Modes

How can I setup my camera?

Let’s go over the basic shooting modes on your camera next, to help you better understand and control your photography.

Shooting modes encompass controls like aperture, shutter speed, and ISO, which contribute to the overall exposure and appearance of your photos.

Auto Mode

Auto Mode, usually marked in green on the camera, allows for fully automatic shooting, with the camera deciding all settings for you, such as aperture, shutter speed, and ISO.

In this mode, additional features like metering mode and white balance are also disabled.

This is a simple mode for beginners to capture images without having to worry about adjusting settings.

Aperture Priority Mode

Aperture Priority Mode (A or Av) allows you to set your desired aperture (f-stop), while the camera automatically adjusts the shutter speed to achieve proper exposure.

This mode is a great starting point for learning how to adjust depth of field in your images.

Depth of field affects the focus, sharpness, and background blur of your photos.

In Aperture Priority Mode, you can experiment with different aperture values to achieve desired effects:

  • Larger apertures (small f-stop number): The subject is in focus, while the background is blurred.
  • Smaller apertures (large f-stop number): Both the subject and background are in focus.

Shutter Priority Mode

Shutter Priority Mode (S or Tv) enables you to select a specific shutter speed, while the camera adjusts the aperture automatically to maintain proper exposure.

This mode is useful when you want to control motion in your images. With different shutter speeds, you can achieve different motion effects:

  • Fast shutter speed (e.g., 1/1000 sec): Freezes motion in crisp detail.
  • Slow shutter speed (e.g., 1/10 sec): Creates motion blur, conveying a sense of movement.

Manual Mode

Manual Mode (M) grants full control over aperture, shutter speed, and ISO settings.

In this mode, you make all the decisions to create the desired exposure for your images.

This mode is suitable for more advanced photographers who understand how these parameters interact and affect the final photograph.

By mastering Manual Mode, you can effectively tailor your camera settings to suit various lighting conditions and creative objectives.

Scene Modes and Drive Modes

There are two important camera settings for beginners: Scene Modes and Drive Modes.

These settings help beginners to capture high-quality photos in various shooting scenarios.

Scene Modes

What is the +/- setting on a camera?

Scene Modes are designed to help beginners quickly set up their camera for specific shooting situations.

These modes automatically adjust the camera settings for optimum results in a given scenario.

Some of the most common Scene Modes include:

  • Portrait: This mode softens the background, focuses on the subject, and enhances skin tones for a pleasant portrait appearance.
  • Landscape: Ideal for capturing scenes like mountains and fields, this mode enhances colors and details for a picturesque landscape shot.
  • Sports: Camera will increase ISO and use a fast shutter speed to capture sharp images of fast-moving subjects, such as athletes or animals in motion.
  • Close-up: Designed for capturing images of small objects, this mode adjusts the camera’s focus and depth of field for sharp and detailed macro photography.
  • Waterfall: This mode maintains a slow shutter speed to capture silky smooth water movement in waterfall scenes while maintaining sharpness in the surrounding landscape.

Drive Modes

Drive Modes determine how the camera takes photos in terms of timing and number of shots.

These modes help a photographer capture the perfect shot depending on the subject and situation. Some common Drive Modes include:

  • Single Shot: The camera takes one photo each time the shutter button is pressed. Suitable for stationary subjects and general photography.
  • Continuous Shooting: Also known as burst mode, the camera takes multiple photos in quick succession when the shutter button is held down, helpful for capturing fast-moving subjects.
  • Self-timer: Allows the photographer to set a delay, usually 2 or 10 seconds, before the shutter is released. Useful for group photos, self-portraits or when trying to avoid camera shake.
  • Interval Timer: The camera takes photos at pre-defined intervals, ideal for time-lapse photography or capturing rapid changes in a scene.

Effects of Light and Motion

Capturing Motion

The ability to capture motion in photography largely depends on the shutter speed.

Shutter speed refers to the amount of time that the camera’s shutter opens to let light pass onto the sensor, and it’s crucial for achieving the right exposure.

It’s measured in seconds and fractions of a second (e.g., 1/250, 1/500, 1/1000).

  • Fast shutter speeds (e.g., 1/1000): Use these for adequately freezing fast-moving subjects, reducing the chances of motion blur.
  • Slow shutter speeds (e.g., 1/30): These are better for capturing intentional motion blur in subjects, emphasizing movement or creating artistic effects.

However, using slow shutter speeds can introduce camera shake if you’re not careful.

To prevent this, consider using a tripod for stability, or follow the reciprocal rule.

This rule suggests that your shutter speed should be no slower than the reciprocal of your lens’s focal length (e.g., 1/50 for a 50mm lens).

How do I set the best camera settings?

Low Light Photography

Low light photography can be challenging, as it often requires striking a balance between sensitivity to light and image quality.

The key setting affecting this balance is the ISO.

ISO determines the camera sensor’s sensitivity to light, with higher values allowing the sensor to capture more light.

  • High ISO (e.g., 1600, 3200): This increases the sensor’s sensitivity to light, making it suitable for low light situations. However, it can also introduce grain or noise in the final image, which might reduce overall image quality.
  • Low ISO (e.g., 100, 200): Use low ISO values to maintain image quality, but it might not be sufficient for capturing images in low light without other adjustments (e.g., slower shutter speed or wider aperture).
ISO SettingLight SensitivityPotential for Grain/Noise
Low (100)LowLow
Medium (800)MediumMedium
High (3200)HighHigh

To further improve low light photography, adjusting the aperture can help. Aperture is the size of the opening within your lens that allows light to pass through to the camera sensor.

Wider apertures (lower f-numbers, e.g., f/1.8) let in more light, making them ideal for low light situations.

A combination of aperture, shutter speed, and ISO adjustments can lead to better low light photographs.

However, it’s always essential to consider the potential trade-offs, such as grain, noise, and blur.

Image Quality and File Formats

When it comes to photography, understanding image quality and file formats is essential for beginners.

This section will provide you with an overview of these concepts, making it easier to make the right choice for your photographs.

Resolution and Image Quality

Resolution refers to the number of pixels in an image, often described in actual pixel dimensions (e.g., 7952×5304) or as Large, Medium, Small (L, M, S).

The higher the resolution, the more detail the photograph will capture.

  • Aperture: It affects depth of field. Use f/1.8-f/5.6 in low light or for a narrower depth of field, and f/8-f/16 for a wider DoF.
  • Shutter Speed: It determines how long the camera’s sensor is exposed to light. Adjust it from 30 seconds to 1/4000th of a second, depending on the scene.
  • ISO: It measures the camera’s sensitivity to light. Choose 100-3200 for entry-level cameras or 100-6400 for more advanced models.

Keep in mind that higher ISO values can introduce noise in your photos, slightly reducing image quality.

Remember to adjust your camera’s white balance to Auto to ensure accurate colors in your images.

File Formats

There are several common file formats used in photography, including JPEG, RAW, and HEIF.

Choosing the right format can make a difference in image quality and file size.

  • JPEG: A widely used format that offers a good balance between image quality and file size. It uses lossy compression, which can result in image degradation if the file is heavily compressed.
  • RAW: This format contains unprocessed image data and provides maximum control over image quality. However, RAW files are larger and require post-processing using specific software.
  • HEIF: A relatively new format that offers similar or increased quality compared to JPEG with smaller file sizes. It’s perfect for rapid image transfer and efficient storage.

Other Camera Settings

In addition to the basic camera settings like ISO, aperture, and shutter speed, there are other settings that can help you achieve creative control and flexibility in your photography.

What are the 3 camera settings that set exposure?

Image Stabilization

Image stabilization is a feature found in many DSLR and mirrorless cameras, which helps reduce the amount of camera shake and blur in your photos.

This is especially useful when shooting at slower shutter speeds or using longer focal length lenses.

Usually, you can enable or disable this feature in your camera settings.

Some cameras may have specific modes for different types of stabilization, such as normal or panning.


The f-stop, often referred to as the aperture value, controls the size of the aperture (the opening in the lens that lets light in).

A lower f-stop (e.g., f/1.8) creates a larger aperture, allowing more light in and creating a shallow depth of field.

This is great for creating blur, or bokeh, in the background of your images.

On the other hand, a higher f-stop (e.g., f/16) creates a smaller aperture, letting in less light and providing a wider depth of field.

This is useful for landscape photography where you want the entire scene to be in focus.

Metering Modes

Metering modes are used to determine how your camera evaluates and measures the light in a scene.

Some common metering modes include:

  • Matrix or Evaluative: Measures light across the entire frame, often the best general-purpose option.
  • Spot: Measures light in a small, single area of the frame, ideal when your subject is backlit or significantly brighter or darker than surrounding areas.
  • Center-Weighted: Measures light in the center of the frame and partially takes into account the surrounding areas, often useful for portraits.

Cheat Sheets

Cheat sheets are a handy way to quickly reference various camera settings based on different shooting situations.

They usually include recommended settings for different types of photography, such as portrait, landscape, action, and low light.

It’s a good idea to find a cheat sheet that suits your camera model or create your own to help you remember ideal settings for certain scenes.

Tips for Beginners

As beginner photographers, it’s essential to develop an understanding of the fundamental camera settings that will help you capture outstanding images.

Below are some practical tips that will aid you in mastering these settings.

  1. Start with Auto mode: It’s perfectly fine to start with your camera’s Auto mode when you’re still learning. This mode automatically balances ISO, aperture, and shutter speed for general shooting situations. As you become more comfortable with your camera, you can gradually transition to manual settings to gain full control.
  2. Learn the exposure triangle: The three main settings that contribute to the brightness or exposure of your photo are ISO, aperture, and shutter speed. Familiarize yourself with each component and how they interact with each other. This knowledge will allow you to take creative control over your shots.
  3. Shoot in RAW format: While it might require more storage space, shooting in RAW format will give you greater flexibility during post-processing. RAW images retain more detail and dynamic range compared to JPEG files, allowing for finer adjustments in editing software.
  4. Use Aperture and Shutter Priority modes: Aperture Priority (A/Tv) and Shutter Priority (S) modes allow you to control one setting while the camera automatically adjusts the other. These modes can help bridge the gap between Auto and Manual settings by providing some creative control while ensuring proper exposure.
