There are a few things you need before starting to Photoshop a tattoo. First, you will need a Tattooed person or model. Second, you will need some basic Tattoo tools. Third, you will need to create a file called “Tattoo_File.jpg.” Finally, you will need to save the file as “Tattoo_File.psd.” To start Photoshop, open the File menu and select “New” from the resulting list. Then, select “Tattoo” from the resulting list and click on the “Create” button. Next, choose your desired size for your tattoo and click on the “Create” button again. Next, choose your desired color for your tattoo and click on the “Create” button again. Finally, choose your desired shape for your tattoo and click on the “Create” button again. When finished creating your tattoo, press OK to close Photoshop and return to the Tattoo_File screen. Now that everything is set up correctly, it’s time to start editing!
