A passport's photo page and most ID cards are laminated or have a glossy protective coating, which reflects light directly back into a camera or scanner far more than an ordinary sheet of paper does. This is why so many passport photos come out with a bright white patch obscuring exactly the part that matters — the photo, the name, or a security feature.
Why glare specifically happens on these documents
A glossy or laminated surface reflects light in a fairly direct, mirror-like way rather than scattering it the way matte paper does, which means any light source positioned at certain angles bounces straight back toward the camera lens as a bright, detail-obscuring patch. The fix is almost entirely about controlling the angle of light relative to the document and the camera, rather than anything about the camera or scanner settings themselves.
Steps to avoid glare when photographing
- Move away from any single, direct light source (a lamp, a bright window, an overhead light directly above the document).
- Use diffuse, indirect light instead — natural daylight from a window that is not in direct line with the document, or an overcast day's light, tends to work very well.
- Angle the document very slightly, rather than perfectly flat, if a specific light source is unavoidable, since even a small tilt can move the reflection out of the camera's direct line of sight.
- Take a few shots at slightly different angles and check each one, since the right angle can vary depending on your specific lighting setup.
Using a flatbed scanner instead of a camera
A flatbed scanner generally handles glossy documents better than a camera, since its light source and sensor are both fixed and calibrated together, reducing the kind of variable reflection a handheld camera in changing ambient light produces. If a flatbed scanner is available, it is often the more reliable option specifically for laminated ID documents.
What to do if glare still appears despite your best efforts
- Retake from a different angle rather than trying to fix glare after the fact in an editor, which rarely recovers detail that was genuinely washed out by direct reflection.
- Try a different light source or location entirely — moving to a room with different, softer lighting sometimes resolves a persistent glare problem that repeated attempts in the same spot could not.
- Use a polarising filter if you have access to one, either as a physical camera accessory or by photographing through polarised sunglasses at an angle, which can specifically cut reflected glare from glossy surfaces.
Combining a front and back scan into one document
Once you have clean, glare-free captures of both sides of an ID card, or the relevant passport pages, combine them into one ordered PDF with Image to PDF, following the general approach in our guide to turning a set of photos into one PDF, rather than submitting them as separate loose images.
Checking the result carefully before submitting
Before using a scanned ID for anything important, zoom in on every piece of text and the photo itself to confirm nothing important is still obscured, even partially, by residual glare or shadow. A document that looks acceptable at a glance can still have a security feature or a small but important detail washed out, which is worth catching before submission rather than after a rejection.
Compressing an ID scan appropriately
ID documents are often subject to specific file size requirements on the forms that request them, covered generally in our guides on image and photo compression targets. Compress only after confirming the scan is glare-free and legible, since compressing a flawed scan does not fix the underlying glare problem, only the file size.
A note on scanning multiple ID documents in one sitting
If you need to capture several ID documents at once — your own and a family member's, for a joint application, for instance — work through each one individually with its own careful lighting check, rather than trying to capture several at once or rushing through them under the same setup without verifying each result. A glare problem that affects one document does not necessarily affect another, particularly if lighting conditions shift even slightly between captures.
Frequently asked questions
Why does my passport photo page specifically have more glare than the rest of the document?
The photo page typically has a more pronounced laminate or protective coating than other pages, specifically to protect the photo and security features, which makes it more reflective.
Does phone camera flash help or hurt with this problem?
Flash generally makes glare worse on a glossy surface, since it is a direct, close light source aimed straight at the reflective material; avoid flash and use ambient or diffuse lighting instead.
Is a flatbed scanner always better than a phone camera for this?
It is often more reliable for glossy documents specifically, though a phone camera with careful lighting and angle can also produce a clean result.
Can I fix glare after the fact in a photo editor?
Rarely fully — glare that has genuinely washed out detail cannot be recovered, since that detail was never captured; retaking the photo with better lighting is the more reliable fix.
Should I remove an ID from its protective sleeve before scanning?
If a plastic sleeve or cover is adding its own additional reflection on top of the document's own lamination, removing it before scanning often helps.
Does this apply to other laminated documents too, not just passports and IDs?
Yes, the same glare principles apply to any laminated or glossy document, including some certificates and cards.
Is the combining tool free and private?
Yes. No sign-up, no watermark, and files are removed from the server automatically about an hour after processing.
