49. How do I know my sensor size?
    • You can typically find information about your camera’s sensor size in the camera’s specifications, manual, or by searching online for your specific camera model.
50. What happens to your picture if the aperture is too narrow?
    • If the aperture is too narrow (higher f-number), less light enters the camera, which can result in underexposed images and reduced depth of field.
51. What happens to your picture if the aperture is too wide?
    • If the aperture is too wide (lower f-number), more light enters the camera, which can result in overexposed images and a shallower depth of field.
52. Is it better to have higher or lower aperture?
    • The choice of aperture depends on your creative and exposure needs. A lower aperture (wider opening) provides a shallower depth of field and is useful for background blur (bokeh), while a higher aperture (narrower opening) increases depth of field.
