  1. 1. (f-number) is a unit that measures the size of the aperture. A lower f-stop means a wider opening and more light; a higher f-stop means a smaller opening and less light.
  2. 5. is the amount of light that reaches your camera’s sensor, determining how bright or dark your photo is.
  3. 7. Mode (Time Value or Shutter Priority) is a semi-automatic mode where the photographer sets the shutter speed, and the camera automatically selects the aperture.
  4. 8. Triangle is a visual model showing the relationship between ISO, Aperture, and Shutter Speed — the three settings that work together to control exposure.
  5. 10. means the photo is too bright due to too much light hitting the sensor.
  6. 11. is the opening in the lens that lets in light. It's measured in f-stops (like f/1.8 or f/16) and affects both exposure and depth of field.
  7. 13. means the photo is too dark due to too little light hitting the sensor.
  8. 14. refers to the camera sensor's sensitivity to light. A higher ISO makes the sensor more sensitive, resulting in brighter images, but can introduce more noise or grain.

  1. 2. Speed is the amount of time the camera's shutter stays open to allow light to hit the sensor. It’s measured in seconds or fractions of a second, such as 1/500s or 1".
  2. 3. (of Light) are units of measurement used to quantify changes in exposure. Changing a setting by one stop either doubles or halves the amount of light.
  3. 4. of Field is the range of distance in a photo that appears sharp and in focus. A shallow depth of field results in a blurry background, while a deep depth of field keeps more of the scene in focus.
  4. 6. Compensation is a feature that allows photographers to increase or decrease the exposure value when using automatic or semi-automatic modes.
  5. 9. (or Grain) is visual distortion that looks like specks or static in a photo, often seen in images taken at high ISO or in low-light conditions.
  6. 11. Mode (Aperture Value or Aperture Priority) is a semi-automatic mode where the photographer sets the aperture, and the camera automatically adjusts the shutter speed.
  7. 12. Blur is the streaking or blurring of moving subjects caused by slow shutter speeds. It can be used creatively or avoided by increasing shutter speed.
