If you don't have the financial ability to buy a big aperture lens, you can play with the blur filter in Photoshop. Lens blur Filter is a very interesting filter, it can well simulate the depth of the lens effect. Do the lens blur to do layer mask or channel mask, otherwise and other fuzzy no difference. Below use two scenery photograph examples to explain lens blur use method, sends up everybody to share.
Example one: This is a flower photo, the middle of the two flower clear, want to let that only bee flower clear, at this time can use "lens blur" to solve this depth of the problem.
Step One: Duplicate the layer, add the mask, and pull a black and white gradient on the mask
Step two: Activate the layer copy (i.e. select Layer Copy), select Filter/Blur/lens blur, adjust parameters. It is mainly two parameters, one is the fuzzy focal length, the other is the radius. The fuzzy focal length determines the position of the focus and the radius determines the size of the fuzzy value. You can modify the layer mask if you are not comfortable with the blurred position.
Example two: This Reed flower photo (of course, useless scrap, here just for example) when filming because of distance, the whole picture is clear, appear messy. To get a picture with the contrast of reality and reality, you can also consider using "lens blur" to solve this problem.
Step one: Copy the layer copy, open the channel panel, create a "alpha" channel, pull a gradient on the new channel
Step two: Activate RGB layer, select Filter/Blur/lens blur, select "Alpha 1" (Alpha 1) channel, adjust blur focal length and radius to fit
