Aperature Challenge – Aperature Priority

I’ve started work on my challenge, trying to demonstrate with photos what happens with Aperature Priority (Av on my Canon camera).
Very briefly, when in Av mode, you as the user set the aperature while the camera takes care of the rest.  In these examples in this post, I set the ISO to 100, but you can leave it to auto ISO mode if you wish.  It was a bright sunny day, so I also set the White Balance to Daylight.
I’ve taken a series of images to try and demonstrate what happens when the aperature changes from a large hole, letting in lots of light, to a small hole letting in a small amount of light.

So in general, if you increase the exposure by one f stop (by that, confusingly it means make the number smaller!) you will double the exposure.
Hopefully you can also see from the examples what I mean by depth of field.  This generally means what parts of the photo are within focus, and obviously depending on what you’re trying to achieve, depends on whether it’s acceptable.
In my rather terrible subject matter pics, I wanted the foreground in focus and the background to change from blurred to sharper.  It works great with flowers pics, if you have a crisp flower and a nicely blurred background.  My table below should summarise what happens in the series of photos.

This was just a brief little forray into my Aperature challenge to prove I’ve not forgotten it.  I’ll be back!
