When a non-artist looks at the elaborate illustration in the last section, the obvious question is "How do you work out all of the details?" For example, how do you decide what will be in the background? How do you decide how each person will be standing? How do you decide on things like facial expressions and arm positions? Hair? Shoes? Hoods? Belts? Weapons? Accessories? These are all details you have to understand before you can start painting.
In the case of the Tolkien illustrations, many of the basic notions and some of the details come from the word-pictures that Tolkien paints. For example, in Chapter 1 of "The Lord of the Rings", Tolkien paints a picture of Gandalf:
In the forward to the book, Tolkien paints a picture of hobbit architecture:
The Hildebrandt brothers spent a lot of time interpreting these descriptions and experimenting with various representations.
In addition, Tolkien gave some instruction into the appearance of things after he wrote his books. For example, in a letter to the Houghton Mifflin company in 1938, Tolkien elaborated on the appearance of hobbits:
This type of word-picture gives the Hildebrandt brothers guidance. So, for example, in a painting that shows Gandalf meeting Bilbo, Gandalf has a pointy blue hat and a long beard, while Bilbo sits in front of a house with round windows and a round door. Bilbo is the right size, has hairy feet and pointy ears.
However, the brothers also have some liberty as illustrators. Tim notes, "When reading Tolkien's text, Greg and I questioned what it would look like if Gandalf's eyebrows stuck out past his hat. We decided not to follow his text literally because his description of Gandalf's eyebrows would have made them almost a foot long."
Given this guidance, there are still thousands of questions for an illustrator to work out. Most importantly, what is the illustration trying to say? What scene does it capture? Who is in the scene? What are they doing? How do they feel? And then there are a myriad of tiny details. For example:
- Where will the "camera" be? Will it be at eye level with one of the characters? Slightly above? Slightly below? Very low, to increase the drama of the shot, or very high to show a broad perspective? Will the camera be close or far away? The illustrator had to figure all of this out in order to establish the horizon line in a painting.
- Where will the light be coming from? One source, two sources? Is it a point source or diffuse? Are there leaves dappling the light (as in the illustration above)?
- What is the light source? Sunlight? Moonlight? Candlelight? Fire light?
- What is happening in the sky? Blue? Grey? Puffy clouds? Heavy overcast?
- What time of day or night is it in the illustration?
- What is the location? Is it an interior scene or an exterior scene?
- As well as all sorts of other details. For example, fences (new, old, freshly painted or not?), wheelbarrows, flowers, grass (freshly mown, grazed, untouched?)
The Hildebrandt brothers initially work out decisions like these in thumbnail sketches, also known as rough sketches. These are quick, small, rough drawings that allow the illustrator to experiment, try different ideas and work out details in a few minutes.
Tim makes two points about thumbnails:
- "Whenever we started working on a new character, we did dozens of drawings. These were quick sketches done without the use of models. Character studies defined movement and personality."
- "According to Howard Pyle, the grandfather of American illustration, you should sketch a scene fifty different ways and imagine yourself as a part of it, not just as an observer. We have been doing this since childhood."
Having worked out the basics in a series of thumbnails, the next step is a rough comprehensive sketch, or in brief, a rough comp. The drawing technique is still quick and rough, normally done in pencil, and it is larger. But the idea is to include all of the elements of the final illustration and see how they all fit together. The rough comp normally goes to the art director who commissioned the work, for his or her approval.
