Ready to create and place your own tattoo? Well now I'll teach you how you can do this in a very simple way.
Start opening a new 300 px x 300 px new document with transparent background.
With the "Elliptical Marquee Tool" draw a perfect circle on the stage (holding "Shift" while you drawing). Fill with black (Edit - Fill).
With the "Right arrow key" move the selection to the right until you have an half moon then hit "Del" on your keyboard.
Now duplicate the layer and with the help of the transform command (Edit - Transform / or / Ctrl-T) compose your tattoo.
This is mine:
Well now merge down all the layer (Ctrl+E) and then, Ctrl + click on the layer to select the tattoo.
Edit - Copy.
Your tatoo is ready, now we'll see how to perfectly place it on a photo.
Place the tattoo into a photo.
Open your photo and go to "Edit - Paste".
Ctrl-T to perfectly resize and rotate the tattoo.
Open now the "Blending options" panel to the tattoo's layer and set:
Set the layer opacity to 80% and the layer mode to "Overlay".
