I took this one with an aperture of 3.5. See how everything in the background is blurry.
This one has an aperture of 5.6. The background is getting a little more detail.
And this last one was set at 8.0, more detail. The smaller you make the aperture, the more detail you have in the background. The instructor said I should have went to a bigger number, than I had to remind him that I only have a point and shoot camera. 8.0 is as high as it goes.
And to illustrate shutter speed, I did this.....
The shutter on this one was real slow to show action. I believe around 1/20 of a second.
Then I sped the shutter up some to get this.
And finally, I speed it up to like 1/2000 of a second to stop all action. You can see I went outside. I was having a problem with lighting. When I would speed the shutter up, I would have to increase the ISO and decrease the aperture. I kept having problems with under-exposure. It was too dark. Guess I need to work on that!
Anyhoo, the assignment for next class is "texture". I have some thoughts about that already.
Oh, we also discussed the histogram last night. If you are interested in that, let me know. I will post a brief description on how to use it if you want.
