Depth of Field

Depth of Field

Most cameras will show you the settings you are or have used when taking pictures

You can check what fstop , speed and iso in the viewfinder , live view or image metadata

The follows examples are to help explain in pictures what effect these three controls have

For this example you need a picture that has three or four at different distances away , such as items with a garden. The idea is to vary the depth of field varying where the focus point is  with different aperture settings (av) It is best carried out using a tripod.

1           Take a control picture using full Auto and write down the settings the camera used

2             Now using Manual mode change the camera to these settings and take it again It should look the same

. Now do steps 3,4,5  and write down the settings after each

3             Change the aperture(fstop) and take a picture where nearest  is in focus

4             Change the aperture(fstop) and take a picture where second   item is in focus

5             Change the aperture(fstop) and take a picture where the third  item (furthest away) is in focus

6             Change the aperture(fstop) and take a picture where fourth (furthest away ) is in focus

Record your settings in the table below
