So in my community college photography class, I’m supposed to be learning how to control depth of field by adjusting shutter aperture (f-stop) and speed.\u00a0 Depth of field, we’re told, is the range of distance \twithin the subject that is acceptably sharp.\u00a0 The higher the f-stop, the longer the range of focus; the lower the shorter.\u00a0 Just to make things confusing, higher f-stop numbers equal smaller shutter apertures, and vice-versa.<\/p>\n

We spent the morning at an outdoor African market, taking photos of pretty things at different depths of field:<\/p>\n

\"depth<\/a>
Longer depth of field (f 8.0)<\/figcaption><\/figure>\n
\"\"<\/a>
Shorter depth of field (f 2.8)<\/figcaption><\/figure>\n

The idea’s that in the upper photo both the close and more distant objects will be in focus; in the lower photo, only the close objects.<\/p>\n

I dunno, I’m not seeing it so much, perhaps because I’m using a point & shoot digital camera with a limited shutter aperture range (2.8 to 8.0).\u00a0 The other students in my class are using fancy-ass digital SLRs with more range; perhaps depth of field will show up better in their homework photos.<\/p>\n

Oops, I take that back.\u00a0 If you click on the photos, then click again, they’ll blow up and you can see the difference.\u00a0 Hot damn, I’m now a\u00a0 master of depth of field, an American sensei<\/em> of still photography.\u00a0 Tremble in my presence, minions!<\/p>\n","protected":false},"excerpt":{"rendered":"
