Aperture

Aperture is not that difficult to understand, think of it as the cameras eye. When you change the aperture on the camera, the light that comes into the picture changes. The aperture size of the flower is large because the background starts to blur out and has a little f-stop number. The smaller the number the less depth of field it has, for example F2 or F3. The picture of the large landscape has a smaller aperture because you can see it has a larger depth in field. Therefore its F-stop is a larger number like F20 or F22. What F-stop is, it’s the focal length divided by the diameter of the pupil. This ios measured by fractions and decimals.
