Module 02
After this section you will be able to choose appropriate autofocus modes and focus points, and apply simple techniques to reduce camera shake and blur.
Most cameras and phones offer at least two primary autofocus modes: single-shot focus for still subjects and continuous focus for moving subjects.
Single-shot focus locks focus once you half‑press the shutter or tap the screen, making it ideal for portraits, landscapes, or still life scenes.
Continuous focus constantly updates as your subject moves, which is better for kids running, pets, or sports.
Focus area settings decide how many focus points the camera uses when it chooses what to focus on.
Wide-area or multi-point modes let the camera guess the subject, which can be fast but sometimes unpredictable.
Single-point or spot focus gives you more control; placing the point over a subject’s eye is a reliable habit for portraits.
Try this: Switch to a single focus point and move it over your subject’s eye or the main object before pressing the shutter.
Even perfect focus settings will not look sharp if the camera moves during the exposure, especially in low light.
A simple rule is to keep your shutter speed faster than the reciprocal of your focal length (for example 1/50 s for a 50 mm lens) when hand‑holding.
You can also brace your elbows against your body, lean against a wall, or use a tabletop or tripod to stabilize the camera.
This video reinforces how autofocus modes, focus areas, and stability work together to create consistently sharp photos.
