My World – Photography 101 Continued – Depth of Field

20180204-122123-3

Our second lesson in our photography class was learning about depth of field and how you increase it by increasing the Fstop at the decreases the aperture which reduces the light hitting the sensor which means you have to increase the iso setting of the camera which makes for more graininess in the photo. It’s all connected in photography, there is no free lunch!!

Anyway I had all week to do the homework assignment which consisted of setting up objects in a line and then decreasing the Fstop from f22 down to f5.6 to illustrate how the depth of field works.  The teacher said that a shallow depth of field works well with portraits, especially those outside, where one wants to “fog” the background to focus on the subject.

So anyway, I waited to do my homework until Sunday when we had a cold front hitting Oklahoma. I decided to use chess pieces for my objects but that did not work well as the wind kept knocking them over.  So as we say in the oil and gas industry I decided to plug back and perforate, in other words proceed to plan b.

I moved the table up closer to the house to protect it from the wind and used a chess board and pieces from my late father-in-law that were a lot heavier. So the above is at f22 and I am focusing on the 3rd pawn from this end. So I shot the same scene at f16, f11, f8, and f5.6, the lowest fstop that my camera with the lens I was using.

So I am still focused on the third pawn and you can see that the rook closest to us might be a might bit fuzzier (we use “might bit” in Oklahoma without irony) and the pieces on the far end are quite a bit fuzzier.  I am sparing you the intermediate photos.

So anyway, next class is Monday night and we will be talking about freezing action with shutter speeds.

I’m still just a lowly picture taker but I’m enjoying myself.
