What is the relationship between aperture and depth of field in photography?

Aperture controls the amount of light entering the lens and affects depth of field. A wider aperture (lower f-stop) results in a shallower depth of field, blurring the background, while a narrower aperture (higher f-stop) increases depth of field, keeping more of the scene in focus.

Can you explain how to choose the right aperture for a portrait?

For portraits, a wider aperture (like f/1.8 or f/2.8) is often ideal. It creates a beautiful background blur, helping the subject stand out. However, ensure the eyes are in focus, as they are crucial for engaging portraits.

What are some common mistakes photographers make with aperture?

Common mistakes include using too narrow an aperture, which can lead to unwanted depth of field, or too wide, which may result in missed focus on the subject. It's also important to consider the lighting conditions when choosing aperture.

How does aperture affect exposure?

Aperture directly influences exposure; a wider aperture allows more light, resulting in a brighter image, while a narrower aperture lets in less light, making the image darker. Balancing aperture with shutter speed and ISO is key to proper exposure.
