One of the easiest ways to amp up the wow factor in your travel photos is to fill the frame with your main subject. Draw the viewer’s eye to the subject of your photo by getting closer or zooming in on the part that matters.
The subject of an image is identified as the object or idea that the photograph is about. It is the primary point of interest that draws a viewer’s eye to the image. Subject matter may be subjective or clearly objective.
