Technical diagram in clean line art style, white background. A generic iPhone in profile view, representing the camera lens positioned at the top back corner. Directly in front of the lens, 3 cm away, is a whole apple fruit depicted as a simple outline or solid black shape with no interior color or shading (monochrome). A red double-ended arrow labeled "3 cm" shows the gap. Narrow blue cone lines (field of view) project from the lens, cropping tightly around a small section of the apple, which appears hugely magnified. Label in black: "Short distance → Narrow field → Large image". Colors: phone (light gray), lens (black), apple (solid black or outline, no color), lines (blue), arrow and distance (red). Mehr sehen
