What paper weight works best for tracing over a screen?

Tracing paper (40–60 gsm) is ideal and allows you to see through even at lower brightness. Standard copy paper (75–90 gsm) works at 70–100% brightness. Cardstock does not transmit enough light for reliable tracing. The lighter the paper, the lower you can set brightness and the less eye strain you will experience.

Will this damage my monitor or tablet?

No. Displaying a bright white image is safe for all display types. The only concern for OLED displays is extended static bright images contributing to gradual wear — for sessions over an hour, reduce brightness to 50% or below on OLED panels.

Can I use this on an iPad?

Yes — iPad Pro with ProMotion display at maximum brightness works very well. Enable the soft-fullscreen mode (the display fills the entire viewport) and use the brightness slider alongside your iPad's hardware brightness control for maximum output.

What is the purpose of the color temperature setting?

Warm white (amber-tinted) is easier on the eyes for long work sessions and gives a softer, more pleasant ambiance. Cool white (blue-tinted daylight) provides better contrast for seeing fine lines through paper. Most artists prefer warm for sketching, cool for technical work.

How does the lock mode work?

Lock mode prevents the fullscreen API from exiting and disables all click/touch events on the canvas. This stops accidental exits when you reach over the screen to adjust paper or rest your hands while thinking. A floating unlock button remains visible at all times.

Can I import an image to trace over?

This tool is a pure light source — it displays a uniform white background. To trace a specific image, open the image in another window, position it, and use the Digital Lightbox for its backlight function. For overlay tracing directly on a reference image, consider a drawing app like Procreate or Adobe Fresco.

Digital Lightbox

Turn your monitor or tablet into a bright light panel for tracing, photography, and animation.

What it does

Precision Brightness Control

Slider from 0 to 100% — critical for dark-room tracing where full brightness causes eye strain through thin paper. Most artists find 30–60% comfortable for extended sessions.

Color Temperature Adjustment

Warm white (2700K) is softer and easier on the eyes for long sessions. Cool white (6500K) gives more contrast for seeing fine details through thick paper.

Grid Overlay

Toggle a faint grid at 10mm, 20mm, or 50mm density for proportion reference while tracing. The grid appears as a subtle light gray overlay over the white background.

Lock Mode

Prevents the fullscreen from exiting when you accidentally move the cursor to the edge or tap the screen while repositioning paper. Unlocks with a dedicated button press.

Tablet Optimized

On iPad and Android tablets, the tool enters soft-fullscreen covering the full viewport. The high-brightness white and touch lock make it particularly effective on bright tablets like iPad Pro.

How to use Digital Lightbox

1
Open the tool
Navigate to devzone.tools/tools/digital-lightbox.
2
Set brightness
Adjust the brightness slider to a comfortable level for your paper weight and room lighting. Start around 50%.
3
Set color temperature
Choose warm white for extended sessions, cool white for fine detail work on thick paper.
4
Enable grid (optional)
Toggle the grid overlay and choose 10mm, 20mm, or 50mm density for proportion reference.
5
Enter fullscreen and trace
Click "Go Fullscreen" or press F. Enable lock mode to prevent accidental exits, then place your paper and begin tracing.

When to use this

Traditional art tracing

Place thin paper (75 gsm or lighter) over your tablet or monitor, reduce brightness to 40–60%, and trace reference images, character designs, or lettering guides without a physical light table.

Animation key-framing

Animators working with physical paper use a lightbox to trace key frames and create in-betweens. A large monitor at 50% brightness works for this workflow when a physical lightbox is not available.

Checking photo negatives

Film photographers hold negatives or slides up to the screen for a quick backlight inspection of exposure and focus before committing to a print or scan.

Architectural and technical drawing

Trace floor plans, elevations, or technical drawings layer by layer, using the grid overlay to maintain scale and proportion.

Tattoo stencil preparation

Tattoo artists use lightboxes to trace custom designs onto transfer paper. A tablet displaying the digital lightbox replaces a physical light table in a mobile setup.

Screen as Light Table: Tips for Better Results

The key to effective monitor tracing is paper choice and brightness calibration. Very thin tracing paper at 50% brightness gives the best combination of visibility and eye comfort. Position the monitor flat (or use a monitor stand with tilt) so paper lies flush against the screen — even a few millimeters of gap introduces blur from the parallax between the screen and your tracing surface.

For longer sessions, reduce brightness gradually as your eyes adapt to the darkness. What seems too dim initially often becomes comfortable after 5–10 minutes of dark adaptation.
