Aperture examples

Below are 2 shots showing different aperture settings taken from my set of test shots the top one is taken at an aperture setting of f3.5 (large aperture) and the bottom one at a setting of f14. The two main differences in the photographs are as follows.

1. The bottom photo is darker than the top one this is because the shutter speed on both photos is set the same 1/20th second so as the bottom photograph has a smaller aperture than the top one this means not s much light has got into the lens and onto the sensor
2. The writing on the "Black Grouse" bottle is out of focus on the top picture (big aperture) but it is in focus on the bottom picture (small aperture) this is because the depth of field is smaller for the bigger aperture.
