Anatomical Heart

No client on this one. I had a booking coming up that wanted heavy stipple shading on an anatomical heart, on a bicep, and I hadn't used that exact dot density on a curved surface before. So the piece got made twice: once on practice skin, and then once on a person.

Stipple shading looks simple and really isn't. Dot spacing that reads as a smooth gradient when it's fresh will close up into solid black once it's healed, and how much it closes depends on depth, voltage, needle taper and how that person's skin behaves. Four variables, all interacting with each other. Guess wrong on a client and you get either a flat grey blob or a gradient that fades away entirely. Practice skin doesn't heal so it can't tell you everything, but it will tell you exactly what your dot spacing and depth consistency look like at speed, and that's most of the problem solved.

I ran the same heart four times across two sheets with different setups: a 3RL, a 5RL, a 9-round shader and a 3-round liner used as a stippler, each at two voltages. Then I photographed all eight at the same distance and light and blew them up side by side. The 3RL at lower voltage won by a mile. The others either closed up or looked a bit mechanical. The study took longer than the client tattoo it was preparing for, which is usually how this goes and is completely worth it. Practice skin is the cheapest thing in the studio and permanent mistakes are by far the most expensive.
