Depth of field…

As my regular readers will know I have recently taken up photography (visit my website at http://www.misselisabeth.co.uk for more pictures).

Being new to this medium I have been playing around with different settings to see the different effects I can come up with and thought this was a good illustration of how depth of field works/looks….

I used a Canon 70D body with a 17mm to 50mm Sigma lens for these shots, not sure about all the technicalities of both the camera and lens yet but I have managed to get some pretty good shots so far.

This was a trailing plant I found overhanging a lovely rustic looking wall in the Little Venice area of Paddington (which I will go back to at some point and do some model shots as it makes for a fantastic background).

Shot 1 – using an f stop of 2.8

f/2.8  1/80 sec. 50mm ISO 100

f/2.8  1/80 sec. 50mm ISO 100

Shot 2 – using an f stop of 5.6

f/5.6  1/20 sec. 50mm ISO 100

f/5.6 1/20 sec. 50mm ISO 100

Shot 3 – using an f stop of 11

f/11  1/20 sec. 50mm ISO 100

f/11 1/20 sec. 50mm ISO 100

Notes (more for new photographers):

  • the higher the f stop the bigger the ‘depth of field’ = basically more of the picture is in focus
  • f stop numbers seem to work in reverse; a lower f stop means a larger aperture (opening/diameter in the )
  • more info about f stops can be found here
  • landscapes are usually taken using a high f-stop (22) so as much as possible is in focus
Hope this has helped to explain the effects of f stops and depth of field.  Please feel free to leave me comments or questions.  In the meantime have a lovely weekend…
