Welcome! I Will teach you the fastest way on faking "Depth of field"
This is the easiest and fastest technique I know, so I am sharing this .
What is "Depth of field"?
Depth of field is the blurred part in an image which defines how far the object from the from the focused object by blurring it.
I use Adobe Photoshop Cs3. Photoshop Cs3 up will do the job.
It took me only 26 seconds to finish the project However, you can be Faster or slower than me depending on your photoshop experience.
Step 1: Open and Duplicate Layer
1. Open your image by pressing CTRL + O then select your image
2. Duplicate layer by right clicking on the layer and press Duplicate
Step 2: Blurring
1. Apply the Gaussian blur. Go to Filter >Blur >Gaussian Blur.
After applying blur, you'll see all parts are blurred.
2. A window with a blur preview will pop up after applying blur. Now, set the radius to 2.7
Step 3: Masking
Let us apply a layer mask
By Going to the lower Layers panel there is a Square with a Circle Icon Click that and it will add something on your layer
Step 4: Putting the Depth of Field
We are removing the blur from our subject that we want to focus.
First, set the foreground color to BLACK and the background color to WHITE
Then, Press the Gradient tool by Pressing G (NOTE: If you press G and it switched on Paint bucket Right click on it and press GRADIENT TOOL).
With the gradient tool, Press and drag it where you want to FOCUS.
You can Experiment with different angles and different line sizes to get the best effect.
Step 5: SAVE IT!
Press CTRL + SHIFT + S then Choose your file name and File format then press SAVE
