Use different shot types to help with the psychology of the image. Shot types might include wide shot, medium shot, extreme close up, dutch tilt, etc.
A wide shot is a shot that shows the subject within their surrounding environment. A wide shot tells the audience who is in the image and where the image is set.
A medium shot is a shot approximately from the waist up. A medium shot is used to emphasize both the subject and their surroundings by giving them an equal presence in the shot.
An extreme close up is shot frames a subject very closely, often so much so that the outer portions of the subject are cut off by the edges of the frame.
A dutch tilt is an angled camera shot where the horizon line isn’t parallel with the bottom of the frame, and vertical lines are at an angle to the side of the frame.
Lastly, snap your picture!
