Scalar
Photograph to finished piece

From the image in your head, or on your screen, to the exact piece in your hands.

Any photo, sketch, or concept image becomes a working reference sized to your exact scale. No tedious math. No wasted materials. Just the first brushstroke, the first piece of foam, the first seam, sized right from the start.

How it works

Five steps, photograph to finished piece.

  1. A photograph of a balcony opened as a reference
    Step 1

    Your image

    Start with the photo, landscape or sketch you want to make. Drop it in from your phone, camera or screen grab.

  2. Setting a known length and output ratio so the reference scales to the working size
    Step 2

    Your size

    Mark one length you already know, then tell it the size you're working at. Every number after that is real.

  3. Lines, arcs and angles measured across the reference photo
    Step 3

    Mapped

    Lines, arcs, angles, circles and curves, measured across the reference and labelled at the size you'll draw them.

  4. The same proportions carried into a coloured-pencil drawing in progress
    Step 4

    Create

    Carry the proportions straight onto the page, canvas, fabric or panel. No guessing, no redrawing.

  5. The finished coloured-pencil artwork
    Step 5

    Finished piece

    The image you loved, made by hand at true size, and it lands right the first time.

Everything the transformation needs

  • Work at the size you're making it

    Scale any reference up or down to true output dimensions. Set one known length and every other measurement recalculates, so a photo becomes a full-size pattern, panel or canvas.

  • Capture the shapes that matter

    Line, arc, rectangle, circle, angle and freehand curve. Trace a three-point arc around a curved edge or read an angle straight off the image, precision measurement for the parts that aren't straight.

  • Straighten what the camera skewed

    Four-point perspective correction flattens an off-angle photo before you measure, so a scene shot from the side still gives you angles and proportions you can trust.

  • Wherever you're making it

    Desktop for close measuring, iPad and Apple Pencil for drawing by hand, phone for a quick reference shot on site. Same project, same accuracy, any device.
