Blur: Bonus Feature!

So, this serves as a “little” addition to last night’s post about blur. Here, I’m focusing specifically on the effect of aperture on background blur. Remember that the same idea applies to foreground blur, as well.

I put together this little animation to demonstrate the effects of aperture changes, as well as how I compensated for the changes in light.


Notice that, aside from the first change, each change in aperture requires half as much time to compensate in light (that’s called a stop, again, another blog). Also, notice how the foreground plant stays sharp throughout, the mid ground plant comes into focus around f/8, and the log in the background isn’t really sharp until f/22.

The foreground plant was about 2 feet (0.7m) in front of me, the midground plant about 3 feet (1m) in front of me, and the log laying behind them something like 8-10 feet (3m) back.

In the next animation, you’ll see what happens when you don’t compensate for the change in aperture.


It got so much darker that I had to add a box to make sure the text was legible… Which I probably should have done for the first animation…

The Hunt for… Blur?

This weekend’s, and my very first blog post on my very own website starts out like I’m certain many of them will in the near future – assignments. I am a student of photography, so it’s only natural that the majority of my assignments are of a photographic nature. I think it’s only fair that I share some of what I’m being taught along the way. Note, I don’t say “what I’m learning” since I’ve actually been doing many of these things for years. So much that a few of them come as second nature, which is the case with today’s topic. Creative blur.

Long exposure and motion photography are by far my favorite types, so I always love the opportunity to explore them more, and in different ways. My digital photography assignment for this weekend allowed such an opportunity, although my execution may have been a bit restrained due to my film photography assignment, which focused on people. Portraits are easily my least favorite type of photography, but that blog will come another day, probably as I attempt to play catch-up with earlier work of mine on this site.

So, let’s dig into the good stuff.
