You probably saw it somewhere else on the web, a piece of scotch tape holding a note? Do you want to know how to do it? Follow this simple tutorial and you will be able to create your own scotch tape in now time.
This example will explain how to make a piece of scotch tape on black background.
Create a new file in Photoshop. In the Channels palette create a new channel using "Create new channel" button located at the bottom of the Channel window.
On the new channel make a square selection using the Rectangular Marquee¹ tool. Fill the selection with white color using the Paint Bucket¹ tool.
Apply Mezzotint filter (Filter > Pixelate > Mezzotint) with value Coarse Dots three times to the channel with selection kept.
Apply Dust & Scratches filter (Filter > Noise > Dust & Scratches). Set Radius value to 8 and Threshold to 0. If these settings don't remove all the noise from inside the square, you will have to adjust values so all the noise is gone.
This will create rough edges for the future piece of scotch tape so it looks like it was cut off.
Make a selection using the Rectangular Marquee¹ tool the size of the scotch tape. Inverse selection (Ctrl+Shift+I). If background colour is not black, reset colors (Press 'D' and 'X'). Clear the selection (Press Delete). Press Ctrl+T to rotate the piece of tape to the required angle (hold the Shift key while rotating).
The channel for the piece of scotch tape is ready. The only thing left to do is bubbles of air inside the tape.
Load selection² from the channel with the piece of tape (Ctrl+Click on its icon in the Channels palette). Expand selection by 1 pixel (Select > Modify > Expand). Create a new channel and fill the selection with white using the Paint Bucket¹ tool.
Apply Mezzotint filter (Filter > Pixelate > Mezzotint) with value Coarse Dots to the channel which was created in step 5 with selection kept.
Remove active selection (Ctrl+D). Apply Gaussian Blur (Filter > Blur > Gaussian Blur) with value 0.4.
This is going to be bubbles inside the tape
Load selection² from the channel with the piece of tape (Ctrl+Click on its icon in the Channels palette) which was first created before. Create a new layer and fill the selection with white using the Paint Bucket¹ tool (background must be filled with black). Set the Blending Mode to Screen and Opacity to 15%.
Load selection² from the channel with the bubbles.
Inverse selection (Ctrl+Shift+I). Intersect selection² with the selection from the channel with the tape.
Create a new layer on top of the layer with the tape. Fill selection with the white using the Paint Bucket¹ tool. Set the Blending Mode to Screen and Opacity to 12%. And you are done!
You are probably wondering how was that intro image made on the white background? Just set tape Blending Mode to Multiply and Opacity to 15%. Change the Opacity of the bubbles layer to 50% and you have it on white background!
