For the second creative Wednesday of the year, I decided to indulge in an exercise of exploring depth of field. Such an exercise should never be undertaken with a dull subject or at a dull location, so I made sure I didn’t make that mistake. Model: Tanya, location: Camperdown Memorial Rest Park. And here I am, on the third creative Wednesday of the year, processing and posting up these images for you – because I know you are the sort of person who might be interested in such shenanigans.

f/3.5, 1/30 sec, at 18mm, 100 ISO, on a Canon EOS 500D
Smallest depth of field achievable with my Canon EF-S 18-55 Lens. The hair is sharpest and the tree is blurry. Having said that, I wonder what would have happened if I tried going away from the subject until I achieved this same framing at 55mm. I know that would ‘compress’ the foreground against the background somewhat but would that look like a smaller depth of field than this? If you have anything to say about that, please do leave a comment below.

The same aperture but a slightly faster shutter reigned in those highlights somewhat and made the tree a smidgen more dramatic.
f/13, 1/6 sec, at 18mm, 100 ISO, on a Canon EOS 500D
I wish I’d taken another shot between f/3.5 and f/13 but here we go – we’ve closed our little friendly hole down to let less light in for a bit longer and voila, we have a larger depth of field. Just as they said we would! The background is a lot clearer now, and wants to be a bigger part of the story. At a sixth of a second the hair is blurred – yep, it was rather windy out there.
f/22, 1/2 sec, at 18mm, 100 ISO, on a Canon EOS 500D
And now all out – a longish half a second exposure at the smallest aperture this lens would do and the background is almost as clear as the foreground, giving us a large depth of field. There’s a lens flare thrown in just to help celebrate the day with a little more style.
So that was a quick exploration of depth of field and it was good fun. There are lots more photos from this day and location, so expect more posts.
One day I’d like to take some photos like these to explore depth of field on a micro scale.
