How to use the Loomis Head construction for tilted-angle reference photos

Why most artists give up on Loomis at tilted angles

The original Drawing the Head and Hands diagrams almost all show the head at eye level. Loomis demonstrates rotation around the vertical axis — the head turning left and right — beautifully, with the brow line traveling around the sphere as a circle. Pitch and roll get one or two pages of treatment and then it's on to features and lighting.

So when you have a reference where the model is looking down at their phone, or laughing with their head thrown back, or a child being photographed from above, the rote method falls apart. You draw a vertical sphere, drop a vertical centerline, and the proportions are immediately wrong. The chin lands where the lips should be. The ears float off the side of the cranium.

The fix isn't a different method. It's the same Loomis construction, with three adjustments to the order of operations.

Adjustment 1 — Re-orient the centerline before you draw the sphere

The default Loomis workflow is: draw the sphere, slice the side planes, drop a vertical centerline, then build out features along that centerline. This works at eye level because the centerline is vertical regardless.

For a tilted head, reverse it. Look at the reference. Find the line from the crown of the skull to the chin. That's the centerline of the head — in 3D, it's the axis the sphere rotates around. Sketch that line first, at the angle it actually appears in the reference. Then build the sphere centered on that axis.

This sounds trivial. It's the single biggest fix. Most failed Loomis attempts at tilted angles fail because the artist drew a vertical-axis sphere by reflex and then tried to deform features off it. You can't recover from that.

Adjustment 2 — Foreshorten the brow-line ellipse

At eye level, the brow line is a horizontal circle around the sphere — it reads as a straight line cutting through the silhouette. The instant the head pitches forward or back, that horizontal circle becomes an ellipse from the viewer's perspective.

The minor axis of the ellipse shortens proportionally to the cosine of the pitch angle. Pitched 30° forward (chin tucked), the ellipse is about 87% as tall as the original circle was wide. Pitched 60° (looking sharply down), it's 50%. Pitched 90° (top of head facing camera), the brow line collapses to a single line cutting horizontally across the cranium.

Drawing this ellipse correctly is the second adjustment. The instinct is to leave the brow line as a curved horizontal — but that gives you a head that's pitched in the silhouette but still facing the camera head-on in its features. The eyes will land too high or too low.

Adjustment 3 — Re-derive the jaw landmark after the tilt

Loomis's jaw point — the chin — sits at a fixed proportional distance below the sphere along the centerline. At eye level: drop straight down by ~1/3 of the sphere radius beyond the bottom of the sphere, you're at the chin.

For tilted heads, the distance stays the same but the direction changes. The chin sits along the new (tilted) centerline at the same proportional offset from the sphere's center. So if you tilted the centerline 40° forward, the chin moves 40° forward of straight-down — toward the camera if the head is pitched toward you, away from the camera if pitched away.

If you re-derive this each time instead of dropping straight down, the lower jaw, lips, and chin land correctly. Skip this and the whole lower third of the face is wrong.

Putting it together: live with the tool

The fastest way to internalize this is to overlay the construction on a real reference. The Loomis Head tool lets you load a reference photo and adjust the sphere's axis interactively — re-orient the centerline first, watch the brow-line ellipse foreshorten in real time, drop the jaw along the new axis. After a few dozen references you'll do it by reflex.

Common references where this matters most

• Babies and toddlers photographed from standing adult eye height — almost always 20–40° pitched forward.
• Phones. Anyone looking at a phone is pitched 15–30° forward.
• Laughter — head thrown back 20–45° pitched backward.
• Sleep — head on a pillow, often pitched sideways (roll) and backward (pitch).
• Renaissance Madonnas — almost universally bowed in tender contemplation, ~15° forward.

These are the reference categories where the eye-level Loomis fails most visibly. They're also the categories that most modern artists draw most often — so getting this right matters disproportionately.
