Camera Settings and Functions: Photography Terms You Need to Master

1. Aperture

Aperture refers to the opening in the lens through which light passes. It’s measured in f-stops (e.g., f/2.8, f/5.6, f/11).

A lower f-number means a wider aperture, allowing more light in and creating a shallower depth of field.

This setting affects both exposure and the amount of background blur in your images.

2. Shutter Speed

Shutter speed is when the camera’s shutter remains open, exposing the sensor to light.

It’s measured in seconds or fractions of a second (e.g., 1/1000, 1/60, 1″).

Faster shutter speeds freeze motion, while slower speeds can create motion blur or allow for low-light photography.

3. ISO

ISO determines the camera sensor’s sensitivity to light. Higher ISO values (e.g., 800, 1600, 3200) increase sensitivity, allowing you to shoot in darker conditions or with faster shutter speeds.

However, higher ISOs can also introduce more digital noise or grain to your images.

4. White Balance

White balance adjusts the color temperature of your image to represent colors under different lighting conditions accurately.

Options typically include Auto, Daylight, Cloudy, Shade, Tungsten, and Fluorescent.

Proper white balance ensures that white objects appear truly white in your photos.

5. Metering Modes

Metering modes determine how the camera measures the light in a scene to set the exposure. Common modes include:

Evaluative/Matrix: Analyzes the entire frame
Center-weighted: Emphasizes the center of the frame
Spot: Measures a small area, usually the center point

6. Focus Modes

Focus modes control how your camera focuses on subjects. Key modes include:

Single-shot AF: Focuses once when you half-press the shutter
Continuous AF: Continuously adjusts focus on moving subjects
Manual Focus: Allows you to focus manually using the lens ring

7. Exposure Compensation

Exposure compensation allows you to override the camera’s automatic exposure settings.

It’s measured in stops (e.g., +1, -2) and can intentionally make images brighter or darker than the camera’s suggested exposure.

8. Drive Modes

Drive modes determine how many photos are taken when you press the shutter button. Common options include:

Single shot: Takes one photo per shutter press
Continuous/Burst: Takes multiple photos in quick succession
Self-timer: Delays the shutter release by a set time

9. Image Quality and File Formats

This setting determines the file format and compression of your images. Options typically include:

RAW: Uncompressed, highest quality, largest file size
JPEG: Compressed, smaller file size, less editing flexibility
RAW + JPEG: Saves both formats simultaneously

10. Depth of Field Preview

This function allows you to see the actual depth of field that will be captured based on your current aperture setting.

It’s useful for precisely controlling which parts of your image will be in focus.

Final Thoughts

We’ve now looked at many important words used in photography.

At first, these words might have seemed hard to understand, but now you know what they mean and why they matter.

Each word we talked about helps you take better photos in some way. Don’t try to remember all these words at once.

As you take more photos, you’ll start using these ideas without thinking about it.

Try using what you’ve learned and see how your photos get better. Every good photographer started as a beginner, just like you.

If you keep trying and enjoy taking photos, you’ll get better and better.

Soon, you’ll be taking pictures that show exactly what you want them to. Have fun taking photos!
