Sign Your Name on a Photograph Using Adobe Photoshop or Photoshop Elements
Creating a Signature
To begin with, create a signature using Photoshop. Write your name / company name / logo and apply whatever blending options you wish to. Make sure that there is no background layer. It needs to be transparent (which is displayed as a checkered canvas in Photoshop). Save it as a Photoshop document (.PSD) File.
Add Signature to a Photograph
Open the photograph in Photoshop. Click on File --> Place and open the Signature file created earlier. Hit Enter to exit the Place menu and then use the Move tool to drag the Signature to your preferred location. (I usually prefer to add the signature to the bottom right.)
Convert Signature to a User Defined Brush
There is however, one disadvantage to the above method. The signature size needs to match the image size in order to provide good results. To circumvent this, one can make use of brushes in Photoshop. After creating a signature, navigate to Edit --> Define Brush Preset in Photoshop to save the signature as a Brush. This brush can be applied onto photographs as and when required and the brush size can be used to resize the signature in order to suit the photograph.
Note: The above series of actions can be performed in Photoshop Elements also with similar results.
