"Bokeh" refers to the quality of the out-of-focus areas in a photograph, derived from a Japanese word meaning “blur” or “haze.” It is assessed by the aesthetic softness and appeal of these areas. Light points are often rendered into blurred orbs. Ideal bokeh is smooth and visually pleasing, with no harsh edges or distracting shapes, focusing attention on the main subject while blurring the background and sometimes the foreground.
In photography, bokeh is employed to produce a visually appealing background that highlights the primary subject, commonly in portrait, macro, and wildlife photography, where a shallow depth of field blurs distractions. In cinema, bokeh adds depth and atmosphere, directing the viewer’s focus within the frame and enhancing the scene's emotional and narrative impact.
ChatGPT understands the term “bokeh” well, so in most cases all you need to do is include it as part of your prompt to get a good effect. Here are the prompts used for these samples:

• a photograph illustrating the concept of bokeh, featuring a sharply focused portrait of a person in the foreground with a softly blurred background, emphasizing the portrait as the primary subject.
• an image illustrating bokeh in an action scene from a fantasy film, with a close-up of the heroine in sharp focus against a blurred background of a magic castle, capturing the intensity and emotion of the moment.
