Fashion photography is typically not considered a type of portrait photography, as it focuses on clothing and accessories rather than the person being photographed.

The rule of thirds is a compositional guideline that divides the frame into thirds, both horizontally and vertically. Placing the subject along these lines or at their intersections can create a more visually appealing image.

Hard light creates strong shadows and highlights, which can add drama and depth to a portrait. It is often used to create a chiaroscuro effect, where the light and dark areas of the image are sharply contrasted.

Having the subject look away from the camera can create a more natural and relaxed expression. It can also help to draw the viewer's attention to the subject's eyes, which are often the most expressive part of the face.

A 200mm lens is typically too long for portrait photography, as it can compress the subject's features and make them look unnatural. It is more commonly used for wildlife or sports photography.

Candid portraits are best captured when the subject is unaware of the camera. This can be done by waiting for the subject to relax and forget about the camera, or by using a long lens to photograph the subject from a distance.

Abstract backgrounds are not typically used in portrait photography, as they can distract from the subject. It is more common to use a simple, neutral background, such as a wall or a piece of fabric.

Cropping the image is the most important step in editing a portrait, as it can help to improve the composition and focus the viewer's attention on the subject. It is also important to adjust the exposure and white balance to ensure that the image is properly lit and has accurate colors.

Fisheye lenses are not typically used in portrait photography, as they can distort the subject's features and make them look unnatural. They are more commonly used for landscape or architectural photography.

The best way to learn portrait photography is to practice. This can be done by photographing friends, family, or even yourself. The more you practice, the better you will become at capturing beautiful and memorable portraits.
