These were all shot with similar lighting condx, but diffrent aperture and exposure settings. I prefer the first one to the other two, probably because the background is so out of focus that it really makes the subject flower stand out.
The other two seem too cluttered due to the presence of a lot of relatively in-focus background. Although cropping could eliminate some of that, they're really cases where a slightly different composition combined with an aperture change could have made a big difference.
This week's assignment was to put your camera into Aperture priority mode and take the exact same photo of an object varying only the aperture.
I rarely shoot in aperture priority mode but I have a setup on the camera to bracket a series of six shutter releases varying the aperture. When I sold my condo I used this to take indoor pictures and then used photoshop to combine the 6 photos and create a high dynamic range version of the various rooms so that both the view from the spacious windows and the interior of the rooms were properly exposed.
The aperture setting of the 21 photos in the stream are part of the file names and range from f1.6 to f16
Thanks Dave - your set not only demonstrates how depth of field varies with aperture, but also how one might want to use aperture to balance light sources - in this case flash vs. natural light.
Hi, Shawn Michael here. I know I have no business commenting on these past posts and all, seeing as I have just been lurking on the forum for the past six weeks or so, without participating. Having said that, re-reading the posts, my curiosity was peaked by Dave's comments about using "aperture" bracket sets to create HDR images. Now I'm really curious. How's that working out for you Dave? I'd love to see the resulting HDR images. I have only used EV bracket sets with fixed aperture and manual focus.
By the way, I must echo Eric's comments, an excellent demonstration on Depth of Field. I particularly like the way the chairs come into focus when viewed as a Slide Show.
Here's pictures of the similar plants with different DoF effects:

Also, which camera offers that bracket feature for HDR?
The Nikon D300 allows you to bracket a number of ways and even includes white balance as a feature to vary with bracketing.

I think I got the DoF but not sure I have tied it in with everything else.

You certainly achieved a narrow depth of field, resulting in an out-of-focus background. Hopefully it was intentional :)
If it doesn't seem intentional - I have missed alot!!
