Grant’s Museum houses the dissections used to illustrate Grant’s Atlas, one of the most well-regarded anatomical atlases in the world. This piece was based on one of the specimens in the museum and demonstrates the ability to fuse real specimens, which can be messy and ambiguous, with information from other sources to create a clear and understandable representation.

Sketching the Museum Specimen

Since photos are not allowed inside Grant’s Museum, I sketched the museum specimen in as much detail as possible. On tracing paper, I sketched the major shapes and copied the labels provided by the museum’s diagram of the specimen.

Shapes and Preliminary Shading

I conducted research to ensure my drawing from the specimen was clear and anatomically accurate. Then, using Adobe Illustrator, I blocked out the major shapes. Afterwards, I went back to the museum and positioned a lamp to illuminate the specimen from the upper left and roughly shaded the illustration.

 
An image showing the major structures blocked out using vector shapes. The pencil sketch is overlaid onto these shapes and preliminary greyscale shading is added digitally.
 

Rendering

Using the preliminary shading from real life observation as a guide, I began to properly shade the illustration. Highlights, cast shadow, and texture were added afterwards. I added more detail and contrast in the area under the cut, since the exposed anatomy was the main focus. Labels were added in Adobe Illustrator after the illustration was complete.
