Select the foreground and background

Step 5: To tell the Afterfocus app about the area which we need to focus on, we select the first tool also called focus selector or foreground selector.

Select this tool and draw lines around your image as shown in the below-given screenshot.  As we are using the smart focus mode, so just draw a few lines which help the app to automatically recognize the focus area.

Step 6: In this step, we will select the background that needs to be a blur. Select the third tool which is background blur it uses the black colours line. To separate the focus area, draw the line at the background of the image as shown in the screenshot.  Remember, the red area is our focus area.

If you have drawn wrong lines then you can use the eraser tool to erase them. Use two fingers for pinch-zoom to select the area at the edges.

Once you selected both the areas, tap on the NEXT button is given above of the app.

Step 7:  Finally, we have separated the focus area and background area. Now, its time to add some effects.

AfterFocus App offers three types of blur: Lens Blur, Motion Blur, and Zoom Blur.

  • The Lens Blur gives you standard blur ground effect which you can see at the below-given image in this step.
  • The Motion blur provides an effect of motion in the blur.
  • The last one Zoom Blur gives an illusion of a zooming effect in the background blur.

We are using right now the Lens blur option.  Under each blur option, you will see two other options: Blur and Feather.

Blur: The Blur option uses to increase the intensity of the background blur.

Feather: If you have some edges of your focus subject those do not appear sharp or feels separate from the background, you can use Feather. It will smooth the edges.

Step 8:  The second effect is the Aperture under which you can set the Bokeh effect for your image. You will get the different type of pre-defined bokeh effects such as circle, pentagon, heart and more. In the given screenshot, you can see the image background light after applying the heart bokeh effect, shows the heart shape. You can also set the intensity of the bokeh using the slider.

Step 10:  The last option in the Afterfocus app is Effect.

You will get four effects under this option: Vignetting, Color Mask, Sticker, and Sharpen. You can use them according to your requirement. The Vignetting will apply some shadows around the background as you can see in the sample image given below.

The Color Mask will separate the background and foreground colour. Sticker allows to some funny things and the Sharpen tool will enhance the clarity.
