<aside> ⏱️ How long the shutter remains open
</aside>
Shutter speed refers to the length of time that the camera's sensor is exposed to light when taking a photo. A faster shutter speed means that the sensor is exposed to light for a shorter period of time, while a slower shutter speed means that the sensor is exposed to light for a longer period of time. Shutter speed is measured in fractions of a second, such as 1/1000 or 1/30. Some cameras will have an additional ‘B’ setting just after the maximum 1 second exposure mark. On this setting, the shutter will remain open for as long as the button is pressed.
<aside> 📏 Which distance to focus on
</aside>
Camera focus refers to the part of the image that is in sharp detail. The focus is adjusted by moving the lens back and forth until the subject appears sharp. Some cameras have autofocus features that can automatically adjust focus based on the subject being photographed.
<aside> 🌊 size of shutter opening / depth of field

Aperture refers to the size of the opening in the lens that allows light to pass through to the camera's sensor. The size of the aperture is measured in f-stops, with smaller f-stop numbers indicating a larger aperture opening and more light being allowed in. A larger aperture opening results in a shallower depth of field, meaning that only a small part of the image will be in focus while the rest will be blurred. Conversely, a smaller aperture opening results in a deeper depth of field, meaning that more of the image will be in focus.
