Aperture depth-of-field comparison reference board

Create a vertical cinematic comparison board showing the same young boy in five stacked horizontal panels, similar to a professional cinematography reference sheet. Each panel shows the same subject, same location, same lighting, same wardrobe, but different aperture depth of field. Panel 1: f/16, deep focus, background clearly visible, subject and environment both sharp. Panel 2: f/11, slight background softness, subject sharp, realistic depth. Panel 3: f/5.6, moderate depth of field, subject sharp, background softly blurred. Panel 4: f/4.0, strong cinematic background blur, subject separated from environment. Panel 5: f/1.2, extremely shallow depth of field, only eyes and face sharp, creamy bokeh background. Use a clean director-style layout inspired by professional cinematography shot reference boards. Add bold aperture labels on the left or right side of each panel: f/16, f/11, f/5.6, f/4.0, f/1.2. Cinematic realistic look, soft natural light, premium camera test aesthetic, consistent subject, consistent framing, no extra text except aperture labels. Aspect ratio 3:4.
