Aperture and Depth of Field

During a recent visit to the lake, as the dog and I were strolling through the forest next door, I decided to play with the aperture settings on my camera. After settling on looking up a poplar tree for my experiment, I rested the camera body on the tree and aimed my 50mm macro lens up towards the sky.

First, I wanted a very narrow depth of field, so I set my f-stop quite low. This meant the aperture was wide open, letting lots of light in:

Then, to see how the same photo would look like with a wider depth of field, I opted for a larger f-stop. This meant the aperture was narrower, not letting in as much light.  I was having trouble focusing on the same spot as the last photo, so while it’s not a perfect compassion, it still works.

You can tell the difference in light by the shutter speed difference between the two shots.  I don’t know about you, but I kind of like the abstract nature of the first shot.

Pyro, by nature

For as long as I can remember, I’ve loved fire. I love the warmth it gives on a cool night, but mostly I love watching the flames dance. It was inevitable, really. The pyro gene is strong on my dad’s side, and I definitely inherited that trait! So it shouldn’t be surprising that the last time I went camping, I was inspired to take out my camera and try to capture the life and beauty of the flames.

I’ve tried taking pictures of fire before, but they never quite satisfied. They were too light, too dark – I couldn’t quite capture what I wanted.

I tried again the other weekend, this time very deliberately. I took a few pictures, looked at the results and adjusted. I even had a tripod! …except I couldn’t use it properly. I’d brilliantly forgotten the bit that attaches to the camera that attaches the camera to the tripod. D’oh! I was still able to use the tripod as a support, just not completely.

I started off with a slower shutter speed, 1 second.

The slow shutter speed blurred things a tad too much for my taste, so I sped it up. But, to compensate for the slower shutter speed, I had to decrease the f-stop (increase the aperture size) and bump up the ISO.

Focusing on a different part of the fire, I slowed the shutter speed down again. This time, I was quite pleased with the results!

One last picture, faster shutter speed. I think this one is my favourite 🙂
