Landscape orientation is horizontal, while portrait orientation is vertical. The subject of your photo will depend on the subject and the message you want to communicate. Landscape orientation is often used for broad, sweeping scenes, while portrait orientation is more intimate and can be used to capture tall subjects.

Photographers began to embrace its social, political and aesthetic potential, experimenting with light, perspective and developing, as well as new subjects and abstraction. Coupled with movements in painting, sculpture and architecture, these works became known as 'modernist photography'.

A portrait is the likeness or representation of someone whether through sculpture, painting, photograph or other artistic media. A picture is a photograph. If a portrait sounds like it has more depth than a picture, it's because it usually does have more depth and tends to offer a story better than a picture does.
