How to light a whiteboard so the photo actually reads.
Short answer
Use diffuse ambient overhead light. Turn off the camera flash. Position yourself so no single light source is directly behind you — that's the primary cause of whiteboard glare. If the room has windows, shoot parallel to the glass, not with the window behind you. Flat, even light from overhead is your best friend.
## Why lighting matters more than camera quality
A whiteboard is a high-gloss reflective surface. Every light source in the room is a potential glare blob in your photo. The camera's resolution doesn't matter if half the board is washed out by a reflection.
## The rules
Rule 1: No flash. Flash fires from the same axis as your camera lens, directly at the board, creating a perfect mirror reflection in the center. Always off.
Rule 2: Diffuse is better than direct. Fluorescent or LED panels flush with the ceiling are ideal — they cast light across the whole room without a single bright point. Spotlights or desk lamps create hotspots.
Rule 3: Light the board from the side, not the front. If you have a moveable lamp, position it 45 degrees to the side of the board, aimed at the board surface. This creates even light across the board without reflecting directly into your lens.
Rule 4: Kill the window behind you. Shooting with a window at your back turns you into a light source pointed at a mirror. Shoot with the window to your side or at a right angle. If the window is unavoidable, close the blinds or block it with your body.
## Specific room types
Standard fluorescent conference room: Leave all the lights on, move to be square-on to the board, and shoot. This is the easiest scenario — even light, no drama.
Modern office with lots of glass and indirect LED strips: Great setup. LED strips are diffuse by nature. Watch for ceiling LED reflections on the board — stepping a half-step left or right often kills them.
Classroom with overhead projector: The projector wash will hit the board if you shoot while it's on. Either turn off the projector or shoot at an angle that avoids the projection zone.
Dim meeting room: Turn on every light in the room. If it's still dim, move a standing lamp to the side of the board and aim it at the board surface from an angle, not from behind you.
## How BoardSnap handles the result
Even well-lit boards sometimes have minor glare. BoardSnap AI is designed to read through moderate reflection artifacts — it interprets content rather than doing raw OCR, so a bright patch doesn't erase what it knows was there. But the better your lighting, the better the output.
Frequently asked
Can I use my iPhone's flashlight (torch) to light a whiteboard?
No — the torch is too close to the lens axis, creating the same problem as flash. Use room lighting positioned off-axis instead.
Does HDR mode help whiteboard photos?
HDR is designed for scenes with both very bright and very dark areas. A whiteboard scene is usually uniformly lit — HDR can actually over-process it. Use standard Photo mode for best results.
