Editors

Interactive editors for working over your photo: the Sphere Editor gives you an adjustable Loomis ball, and Manual Grid lets you build your own proportional grid. They work side by side — more are on the way.

Sphere Editor gives you an editable Loomis sphere, seeded from the detected head pose so it starts aligned to the face. Turn it on to replace the static Loomis overlay (they are mutually exclusive; the previous state is restored when you turn it off).

On photos with the head tilted far up or down the automatic fit is unreliable, and the upload shows an amber notice saying so. The photo still processes — drag the sphere onto the face here to correct it.

OTurn the Sphere Editor on / off (same as the SPHERE button).
Drag inside ballOrbit — rotate the head: yaw ±90° (full profile), pitch ±70°.
White dotMove the sphere.
Gold squareResize the sphere.
Red squareRoll — drag left / right to tilt the sphere in the screen plane (±90°). Rides the rim as it turns.
Blue squareAbove the center line — drag left / right to shift its top (same as the Center L/R slider).
Green squareBelow the chin line — drag left / right to shift its bottom (same as the Chin L/R slider).
Drag outsidePan the image.
ElementsToggle visibility of each line (interface, skull, shadow, hair, brow, nose, chin, center, jaw, dot lines).
;Dot lines — dashed rings through the brow→nose divisions, parallel to the brow line. Off by default; same as the DOT LINES element.
InterfaceHides every handle and turns off orbit — the construction stays, dragging just pans the image.
Pose slidersFine-tune yaw, pitch, roll and the center / chin line offsets. Drag with the mouse or step with arrow keys.
Undo / Redo / ResetStep through edits; Reset returns to the detected pose.
Line OpacityFade all sphere lines from full to invisible.

Manual Grid is a different way to draw: instead of following a construction, you box the head in and let the grid carry the proportions. Mark two horizontal lines — usually the top of the skull and the bottom of the chin — then two vertical ones down the sides. Each pair is split into quarters automatically, giving a 4×4 grid you can copy square by square onto paper.

Where you put the side lines is a matter of taste: the hair silhouette or the skull contour both work, as long as you stay consistent. Press Y to subdivide when you need more reference — 4×4, then 8×8, then 16×16, then back off. Pair it with Tone Levels to read the values inside each square while you shade — and press / (or the # button) for a swatch column of those values to compare against.

H / VPlace a horizontal / vertical line. Two clicks make a pair; the grid appears once both pairs are down.
Tilted / LevelLine angle: follow the head tilt, or run square to the page. Locks once the first line is placed.
YSubdivide the finished grid: 8×8, then 16×16, then off.
B / NUndo / redo the last pair.
✕Clear the grid and close the editor (Escape does the same).

Tone MethodAuto places the steps where the photo's own tones cluster, so every step carries detail — the safe default. Grid spaces them evenly across black to white regardless of the photo. One is active at a time, and neither runs while the stepper is Off.
Tone BiasGrid only (−80 to +120). Shifts the photo along the steps before they are applied, like exposure: push it up and the light areas blow out to white until only a line drawing is left, pull it down and the darks sink into a single black mass.
Tone # (or /)Swatch column — draws a stack of squares down the top left corner of the photo, one per tonal step, darkest first, in the exact greys the steps are painted with. Hold a square against an area of the photo to read which value it is. Only the steps actually on the image are listed: Brightness and Contrast run before the tone pass and can flatten several steps away entirely, so a 6-step setting may really be 2 — the column shortens and the stepper reads 2/6 in amber to say so.

Loomis & Reilly head construction lines from a photo

Loomism is a free tool that overlays Andrew Loomis and Frank Reilly method head construction lines directly onto a face photo. Upload a portrait and it detects the facial landmarks, estimates head pose, and draws the construction guides automatically — no manual grid alignment, no signup. It runs online in your browser — there is no app to download and no install — so you can use the Loomis method on a photo straight away. Use it as a drawing reference to study proportions, check your own portraits, and learn to draw heads from any angle. The full user manual walks through every feature step by step, and is also available as a PDF download.

Loomis method from a photo

The Loomis method builds the head from a ball-and-plane construction: a cranium sphere with a flat side plane, divided by the brow line, hairline, nose line, jaw line and a vertical center line. Loomism fits this Loomis head construction to your reference photo so the brow, hairline and nose lines curve correctly with the head's pitch — front, three-quarter, side profile, tilted up or tilted down. Because the fit is automatic, you get the Loomis head construction step by step on your own reference instead of copying a diagram — the same drawing works from every angle. The center line is subdivided along two spans (brow→nose and nose→chin) with quarter and third division ticks, so you can check the vertical placement of the eyes, nose and mouth against Loomis's proportions.

Reilly method rhythm overlay

The Reilly method abstracts the head into rhythmic curves — the facial ovals, eye, brow and nose construction, cranial arcs and undercheek rhythm — that capture flow and likeness. Where Loomis nails the structure, the Reilly abstraction brings the portrait to life. Loomism draws the Reilly rhythms on the same photo so you can study both — a fast way to bring Reilly abstraction into your head drawing practice without redrawing the layout by hand.

Loomis vs Reilly — what's the difference?

The Loomis method is about structure and proportion: a simple ball-and-plane head a beginner can place in seconds. The Reilly method is about rhythm and likeness: flowing lines layered over that structure. They complement each other, and Loomism lets you overlay Loomis, Reilly, or both together on a single reference image. Artists often compare these two with the Asaro head, a planar model for studying light and shadow; Loomis and Reilly are about construction and rhythm, while the Asaro head is about planes.

Facial proportions checker

The proportions overlay measures the classic drawing rules — the rule of thirds, five-eye-width spacing, alignment lines and ratio measurements (height/width, eye/face, nose/eye, mouth/nose) — so you can check whether a portrait's facial proportions are accurate against the reference photo.

Frequently asked questions

What is the Loomis method?

A head-drawing technique by Andrew Loomis that constructs the head from a ball (the cranium sphere) and a flat side plane, divided with brow, hairline, nose and jaw lines, to draw a face from any angle.

Can I use the Loomis method directly on a photo?

Yes — Loomism detects facial landmarks and head pose automatically, so the Loomis and Reilly construction lines align to your photo without placing a grid by hand.

Is Loomism free?

Yes. It runs in your browser with no signup. Upload a face photo and download or print the Loomis, Reilly and proportion overlays.

Is there a Loomis method app?

Loomism is a free Loomis method app that runs online in your browser — there is nothing to download and no APK to install. Open it on desktop or mobile, upload a face photo, and the Loomis head construction lines are drawn on it automatically.

Can I use the Loomis method on a side profile?

Yes. Loomism estimates head pose, so the construction lines fit a side profile, a three-quarter view or a front view. The brow, nose and jaw lines curve with the head's pitch, which is what makes the Loomis method work from every angle.

How do I draw a head from any angle step by step?

Start with the ball and plane: a cranium sphere with a flat side plane, then place the centre line, brow line, nose line and jaw line. Loomism shows this step by step on your own reference photo, so you can copy the construction onto paper instead of guessing the proportions.
