How to Trace a Drawing With Your Phone
You do not need a light box, a printer or tracing paper. A phone can do the same job in two different ways, and which one you pick depends on whether you want to draw on the screen or on real paper.
Short answer: put the picture on your phone screen and draw over it with the screen as a guide, or hold the phone over a sheet of paper and use the camera overlay so the lines appear on the page while you copy them by hand.
Method 1 — the screen as a guide
This is the closest thing to a classic light box. You open a sketch, place a thin sheet of paper against the screen, and the bright lines show through so you can follow them. In Line2Art this mode is called Trace it.
- Open a sketch from the gallery.
- Tap Trace it.
- Turn the screen brightness up and lay thin paper over it.
- Follow the visible lines with a pencil, then lift the paper and finish the details.
Works best with thin paper, simple line art and a phone or tablet you do not mind pressing on. Use light pressure — a pencil, not a ballpoint.
Method 2 — the camera overlay on paper
Here the phone stays above the paper and shows you the camera picture with the sketch laid on top of it. You see your own hand, your own pencil and the sketch in the same frame, and you copy what you see. This is the Draw with camera mode, and it is the one to use when you want a full-size drawing on a real sheet.
- Prop the phone above the paper — a stand, a stack of books, or a clamp all work.
- Point the camera at the sheet and pick a sketch.
- Adjust opacity, size and rotation until the lines sit where you want them.
- Lock the image so it stops moving, then draw what you see on the screen.
The overlay has opacity, brightness, contrast, edge blur, flip, rotate and zoom controls, so you can make the guide as faint or as strong as you need.
Which one should you use?
- Small drawing, thin paper, no setup — use the screen as a guide.
- Full-size drawing, thick paper, sketchbook — use the camera overlay.
- You want to learn, not just copy — use step by step mode, which reveals the drawing in stages instead of all at once.
Tips that actually help
- Keep the phone still. Most bad traces are camera shake, not bad drawing.
- Lower the overlay opacity as you go, so you end up looking at your own lines.
- Start with shapes that have few lines. Simple line art traces far better than shaded art.
- Do not trace the whole thing. Trace the proportions, then draw the details freehand — that is where the practice happens.
