EnchantedTo try out aperture priority mode (P with the Nikon 5100) I've chosen to take photographs of flowers.
I used different aperture settings to achieve the effect of a blurred background while the flower is in proper focus, which worked best with a photograph of a buttercup blossom, because the background was far enough.
F/5.3, 1/200 sec, ISO-400
A second picture shows a pink tulip. Here the background is also blurred, but less. An additional effect here is that my camera was slightly tilted, so that corresponding to this the blurring distributes.
F/5.3, 1/250 sec, ISO-400
In a third photo, which is a photo of daisies in a meadow, the effect is not so distinguishable, but it is interesting to see that background and foreground is blurred and just the middle ground is in focus.

F/8, 1/100 sec, ISO-100
Next I've experimented with shutter speed priority (S with the Nikon 5100). I took two photographs of running tap water with different shutter speeds. The effect is that with low shutter speed the running water is blurred and with a high speed it appears frozen.
I had to set the ISO value rather high, which is the reason the frozen version with a shutter speed of 1/1600 became rather dark. I had to lighten it up with the photo editing software ViewNx2.
I will soon add more of the ways of my camera.
