Realistic Tattoo

For some finishing touches, add some blood drips and splatters around the ripped skin and on top of your tattoo. Making blood spots can done with custom brushes or using stock photos of fake blood and red paint on a white background. Finally, brush in some additional shadows, highlights, and adjust the color of the tattoo to finish off your composition.

Just under your shadows layer, make a new layer for lightly brushing in a red hue around the area of your "real" tattoo. This is to give the effect of the skin becoming irritated by the tattoo's transformation. To stretch the skin slightly, use the Smudge Tool with a low strength on the model's layer. Make short outward strokes where the skin would appear to be affected.

Press "d" and then "x" to change the foreground color to white and background color to black. Now copy your tattoo layer (Ctrl + J) and use the new layer to apply a Stamp filter, found in the Sketch filters menu. Play with the settings until you get your desired tattoo result. For the example below, the light/dark balance was set to 25 and the smoothness to 5. Another filter you may want to try is the Photocopy filter. Note: it helps to be working with larger images to maintain detail. Once your tattoo is ready, set the layer blending mode to Multiply, and turn down the opacity to about 90%.

Open your tattoo photo in Photoshop and use the Pen Tool (video tutorial) to outline the object from the background. Now right click on the canvas and choose "Make Selection". Copy the selection (Ctrl + C), open your model photo, and paste it into a new layer (Ctrl + Shift + N) on top of your subject. Position the tattoo to your liking.

Start out by sourcing your stock photography. You'll need a compelling subject with a fair amount of bare skin for tattooing. In this case, we'll use a model with plenty of uncovered area. While searching for the right photo of your desired tattoo, keep in mind the position and angle it will lay on the skin. For this tutorial we'll use a straight-on shot of a python.
