In this tutorial we are going to make a “Floating Tab”. It is basically a technique of using drop shadow on objects to give them a FLOATING look. Ok, so lets start now.
Create a new document and draw a tab of 250 x 35 pixels. Dimensions may vary according to the requirements.
Now fill that rectangle with any color of your choice.
Now create another layer, but make sure the new layer should be UNDER the tab’s layer. Means the tab layer should be UP and the new layer at bottom.
Now take the polygonal lasso tool and draw shape like this,
Now change the opacity to 32%. This is the final result I came up with
I hope you too will come up with the result you expected.
