First, download this image from the description.
Open in photoshop.
In this class, we will learn how to use lens blur for blurring the background and not effected the foreground.
Now we will use the pen tool to select this TV.
After that, we will click right and press “make selection”
Father radius will be 1 px. Hit ok.
Now select “quick selection tool” to save this selection.
Click the right button here to find out the “save selection” option.
Write a name for this selection.
Go to the channel’s panel and here you will see your saved selection is in here.
Now we will click here to make a new “alpha 1” layer.
Then we will select the gradian tool and draw it from the above to the bottom.
You can see our background is red marked and foreground is not.
That red side of this picture will help us to make it blur.
And the normal side will remain as normal.
Click CTRL+Right key or CMD+Right key here to reveal the selection of “alpha 1”.
Then hit CTRL+Shift+Right key or CMD+Shift+Right Key for merging the two selections into one.
Click outside of this layer option to remove the red mark from this layer. Then select the
“layer 0 copy” again.
Go to filter-blur-lens blur, Select the source must be “alpha 2”
You can see our shoe part is a blur but the TV is focused.
You change the focal area by using this “blur focal distance”
You can adjust how much blur you want in your background or foreground by this bar called “Radius”
You can use the tool called “set focal point” to point out that where you want to put the blur effect.
Like when I point in the background the shoe’s blur is gone but now the TV is blurred.
And same when I click on this TV, TV’s blur gone but the shoe is blurred again.
You can click invert to change the blur direction. You can test with your other option also.
Hit ok. Now you switch off your “layer 0 copy” to see the difference between before and after-effects.
CTRL+D or CMD+D for deselecting the selection.
You can see our TV is a little bit blurred to remove that we have created a mask.
Click on the mask icon to create a mask.
Make sure your foreground color is black.
Select the brush tool.
go to the channel’s panel and click CTRL+Right key or CMD+Right key
to select the “selection 1’s” selection.
Now you can remove the little blurriness from the TV by brushing on it.
