This photo shows a wide aperture as the plant that is close to the camera is in focus whereas the objects in the background are blurred. This has been done to draw the focus to the plant. To create a wide aperture I went into the settings of the DSLR camera I was using and selected an aperture level that I liked.
This photo of water coming out of a drinking fountain demonstrates a fast shutter speed so that you can see the movement of the water and the shapes it creates. Different shutter speeds are used to create different effects when there is movement. A slow shutter speed will not capture all the details of a moving object and will have a motion blur because of this. To change the shutter speed I went into the settings on the camera I used and increased the shutter speed.
This photo shows a low ISO. This means that the camera is less sensitive to the light which creates a darker image. I lowered the ISO by going into the camera settings.
This photo has had a tilt shift applied to it in Photoshop. The tilt shift effect makes the people and objects it has been applied to look smaller and further away than the people and objects a tilt shift has not been added to in the photo. There were many steps to creating this effect.
First I selected the image and went into quick mask mode. Then I applied a vertical gradient to create the effect in the image below.
After this I exited quick mask mode and applied a lens blur by going to filter in the toolbar at the top and then selecting blur and then lens blur. then I adjusted the blur.
Then I changed the saturation of the image to complete the effect by pressing Ctrl + U on the keyboard.
