Do you aspire to taking portrait images? Many times, an apprentice photographer makes a mistake by setting the camera in portrait mode and then clicking immediately.
However, this will not give you top quality images and you will not get much satisfaction.
Whether you use a DSLR or Digital camera, you probably have portrait mode in the camera settings.
By setting the camera in automatic portrait mode, you get the flexibility of clicking the images in portrait mode. Even a person who is not at all familiar with the camera and its setting can take portrait images this way.
