Upstairs Playroom - Photography Class Aperture Study
Nikon D90, 35mm 1.8 - shot in RAW
Tripod Mount, Manual, No Flash, ISO 250, SS 1/250, f/1.8
There is nothing particularly beautiful about this picture. It was one of a series of shots that I took for a homework assignment for my photography class. Of course, I misread the directions and shot in manual when we were supposed to be using aperture priority, but the end result isn't different, it just took a few seconds more to switch the settings.
But, I do like this picture because of what it does capture, intense effort from both girls (look at their necks), the pinwheel still in motion, and a soft, out-of-focus background.

Our assignment was to shoot at the highest, lowest & middle aperture for our lens. I would have liked to be outdoors, but had to go where my subjects were willing.
Wide Open @ f/1.8

After the first shot I opened the windows more, so that I had to double the shutter speed for proper exposure, which caused the motion to freeze as compared to my favorite shot above. I could have raised the ISO, and gotten a similar result - so many little things can change the mood even with the same exposure result.
Stoppedd Half-way @ f/6.3

I thought this would be my favorite setting because the motion would still be seen, but the background is still slightly blurred.
Just goes to show what a little difference in lighting can make - shooting in a slightly darker setting got a similar result wide open, but with a more OOF background, something I prefer when I'm indoors in a cluttered house.
Stopped all the way down @ f/22

here the movement made by Iva blowing is picked up by the longer exposure, but the background is very clear, even the reflection in the windows.
