Focal length matters
Lens shape and material determine how strongly light is bent.
Real images can be projected
A camera lens forms an image on a sensor or film.
Magnification changes apparent size
Optical systems trade field of view, brightness and detail in different ways.
Resolution is not just magnification
Making an image larger does not automatically reveal information that was never resolved.
