While camera settings are important for technical aspects of the photograph, they do not directly influence the capture of expressions.

Focal length determines the field of view and compression, which are crucial for framing and isolating the subject in a portrait.

Rembrandt lighting involves placing the light source at a 45-degree angle to the subject's face, creating a distinctive triangle of light and shadow.

The rule of thirds involves dividing the frame into thirds both horizontally and vertically, creating nine equal sections. Placing key elements along these lines or their intersections can enhance the composition and visual interest.

Candid portraits aim to capture the subject's natural expressions and emotions, often without their awareness, while posed portraits involve directing and controlling the subject's pose and expression.

Harsh lighting is generally avoided in portrait photography as it can create unflattering shadows and detract from the subject's emotions.

Establishing a rapport with the subject helps them feel more comfortable and relaxed, leading to more natural and expressive portraits.

Reflectors are used to bounce light back onto the subject's face, reducing shadows and creating a more even and flattering lighting.

The Dutch angle, which involves tilting the camera, is not commonly used in portrait photography as it can create a sense of unease or disorientation.

Candid shots often capture more genuine and natural smiles compared to posed shots where the subject is consciously trying to smile.

In portrait photography, the background should generally be simple and uncluttered to avoid drawing attention away from the subject.

Split lighting is not a common portrait lighting pattern as it creates a harsh and unflattering shadow across the subject's face.

Using a wide aperture creates a shallow depth of field, which blurs the background and draws attention to the subject's eyes.

Softboxes are used to create a soft, diffused light that reduces harsh shadows and produces a more flattering and natural look.

Adding filters and effects is generally not considered a common editing technique in portrait photography, as it can detract from the natural look of the image.
