The smaller the f-number, the bigger the aperture (big opening) and the less depth of field (blown out background). The bigger the f-number, the smaller the aperture (smaller opening with clearer background) and the greater depth of field. What is the relationship between f-number and aperture size?
1) As the f-number decreases, the aperture size increases
2) As the f-number decreases, the aperture size decreases
3) As the f-number increases, the aperture size increases
4) As the f-number increases, the aperture size decreases
