Final answer:
Janice has used the depth of field technique in photography to create an appealing image by blurring the background and focusing on the subject.
Step-by-step explanation:
Janice has used the technique of using a shallow depth of field in photography to make certain areas out-of-focus and blurry. This artistic technique emphasizes the subject by blurring the background and any potentially distracting elements. It is often achieved by using a larger aperture setting on the camera, which results in a narrower depth of field, allowing the subject to be in sharp focus while the foreground and background become out of focus.
This can also be accompanied by changing the shooting angle or zooming in to further minimize distractions and unwanted elements in the photograph. Such practices align with the artistic principles of framing and composition, where unwanted artifacts or distracting details are either used artistically or eliminated to enhance the visual storytelling of the image.
