I wanted to refer to a post I had previously written on depth of field for my other blog but rather than just provide a link to my other blog, I wanted to keep everything in one place for this course so have copied and pasted the text/photographs verbatim [Posted on https://misselisabethuk.wordpress.com/ on 3 October 2015]:
“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
Shot 2 – using an f stop of 5.6
Shot 3 – using an f stop of 11
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…”
On reflection, with 5 months having past since I posted the above on my other blog, I still think they are a great example of how depth of field changes with a change in f number / f-stop.
Looking past the technical and now more to the composition what strikes me is that the colours work particularly well together, the red/green of the leaves against the red/neutral tones of the brick wall. My preference even now is for a shallow depth of field, I like this look in what probably is more of a portrait style image granted.
It’s also nice to look back at work you have previously produced with a sense of knowing that this is the right path…
