Weekly Picture Project: Week 5 (Exposure)

This week’s Picture Project letter was “E,” so we decided to focus on “Exposure,” with a little bonus time going to depth of field again. So, here is what I came up with:
In these first three pictures, I was basically trying to do a “good” exposure, an underexposure, and an overexposure. All were shot at f/22 and an ISO of 1600 (probably shouldn’t have set the ISO to automatic, but oh well):

“Good” exposure: 1/13th of a second

Underexposed: 1/40th of a second

Overexposed: 1/5th of a second
In these next four pictures, I just decided to narrow the depth of field by using a wider aperture (and a smaller f-stop number). I thought it would be interesting to focus on each bagel in turn. Each is shot at f/1.8, most for around 1/125th of a second:




I guess the following two aren’t anything special, but the first is taken at f/1.8, and the second is at f/22. I was still learning about exposure, so the ISO ratings are way different, so I kind of missed the mark on the results. As I said, though, at least I learned a bit, which is the point of the Picture Project:

f/1.8

f/22
I think these last three turned out a bit better. They were all shot at the same ISO, at least (100), and they show the results of an increasingly wide depth of field:

f/1.8; 1/4,000 sec.

f/6.3; 1/500 sec.

f/11; 1/160 sec.
For these three pictures, I guess it’s a matter of personal preference which looks better. I like the deeper blue sky in the latter two, but I like the narrow depth of focus in the first one, which helps some branches stand out, and lets others go blurry. However, there’s not really a central subject in these pictures, so maybe the last one is better, since it’s all in focus.
Any thoughts?
So, that’s it for now. Thanks for checking out the pictures!

  1. Oh- and the differences in the color of blue sky has to do with exposure, not just the DOF that is accomplished from the small f/stop. If you look at the branches the color shifts. If your exposure was the same they all should be the same color – the sky would be the same color too.

  2. @Brad – Yes, still just rocking away with the 50mm, and I love it. I guess I’m still curious to try out others, though.
    And that’s a good point about the sky. Hadn’t really considered that.
