Plain white, evenly lit, no shadow behind the head. That is the entire Cambodia eVisa photo background rule — and you can hit it with a phone and a white wall in your living room, no studio required.
A plain white or very light off-white background, evenly lit, with no shadow behind your head, no gradient, no pattern, no furniture, and no other people in the frame. The face must be fully visible and centered with a neutral expression. The most common reason an American photo gets flagged is not the wall color — it is a shadow cast on the wall behind the head from overhead or angled light. You fix that by standing a foot or two off the wall and lighting your face from a side window. A phone photo against a white interior wall in daylight meets the rule every time when you follow a short routine. No studio or booth is required.
Plain white, evenly lit, nothing behind your head. That is the whole Cambodia eVisa photo background rule, and it is simpler than most US travelers assume. The photo is just one piece of the wider Cambodia visa for US citizens process, and the background is the piece that flags the most applications. There is no special shade of white to match, no studio backdrop to buy, and no need to leave your house. What trips Americans up is rarely the wall itself — it is the shadow that artificial or overhead light throws onto the wall behind the head, which the upload validator reads as a gray or patterned background and bounces.
A clean photo background does two jobs at once. It lets the system isolate your face and the edges of your head against an even field, and it gives the Cambodian Immigration officer at the kiosk a clear match between the printed PDF and the person standing in front of them. A busy, dim, or shadowed background breaks both of those, which is why the background is checked as strictly as the expression and the framing.
This guide covers exactly what counts as an acceptable background, the shadow problem that flags most American photos and how to eliminate it, the no-studio window-light method step by step, and what to do if your photo still gets flagged. If you want the full specification beyond the background — size, expression, glasses, file format — start with our Cambodia eVisa photo requirements guide and use this page as the deep dive on background and lighting.
The background needs to be a single, uniform, light field behind your head and shoulders. Plain white is the target. A very light off-white or pale neutral gray reads fine in practice, but pure white is the safest choice because it leaves no room for the validator to call the field too dark. The key word is uniform: the whole area behind your head must be one even tone, top to bottom and side to side.
Background is only one of the things the system checks, and a flagged photo often has more than one issue at once — a shadow plus a slight smile, say. If your photo keeps coming back, our guide to the most common Cambodia photo rejection reasons walks through every flag in the order the system applies them so you can clear them all in a single retake.
Here is the thing most US travelers miss: the wall can be perfectly white and the photo still gets flagged, because of the shadow your own head casts onto it. When light hits you from above or from one hard angle, your head blocks it and drops a dark patch onto the wall directly behind you. The validator does not know that patch is a shadow. It just sees that the background is no longer one even tone, and it calls it non-uniform.
This is why the ceiling light in your kitchen or the lamp on your desk is the enemy. A single overhead bulb sits above and slightly behind you, which is the exact geometry that produces the worst head shadow. The harder and more direct the light, the sharper and darker the shadow. Late-evening photos lit by a single warm bulb are the most common flag we see from American applicants, and they are almost always taken under a ceiling fixture.
There are two levers that kill the shadow, and you use them together. First, get off the wall. Standing pressed against it guarantees the shadow lands right behind your head; standing a foot or two away pushes the shadow down and out of the frame, and lets the wall stay evenly lit on its own. Second, light your face from the side, not from above. Soft daylight coming through a window beside you wraps around your face and leaves the wall behind you clean.
If you are shooting on an iPhone, there are a couple of camera settings that make the shadow problem worse — Portrait mode and the front camera both work against you here. Our iPhone photo guide for the Cambodia eVisa covers the exact capture settings, and the broader phone-photo walkthrough shows the whole routine if you are on Android or just want the full sequence.
You do not need a photo studio, a booth at the drugstore, or any gear beyond a phone. A white wall, a window, and a few minutes is the setup most American applicants use, and it produces a clean compliant background every time when you follow the routine below. Plan it for mid-morning or mid-afternoon on a bright day, when daylight is strong but not yet warm and orange.
Before you upload, check the frame on a bright screen. Is the wall behind your head one even white, corner to corner, with no shadow patch and nothing poking into the frame? Is your face evenly lit, with no dark side? If yes, you have a compliant background. If the wall looks gray, the room was too dim — wait for better light or move closer to the window. If there is a shadow, step further off the wall and move the light more to your side.
Save the result as a JPEG under 2 MB, 600x600 pixels or larger, cropped square with your head centered and a little headroom above the hair. Modern iPhone and Android cameras shoot well above that resolution, so you may need to crop to a square in the Photos app before upload. Do not run a filter, a beauty mode, or any smoothing — the system rejects heavily edited photos because they no longer show natural skin texture.
Most US applicants have a usable white wall somewhere at home. A few situations need a small adjustment, and none of them require a studio.
No white wall in the apartment? A closed white door, the back of a white closet, or a roll of white craft paper taped flat to any wall all work. A white bedsheet pinned tight so it has no wrinkles is the classic fallback — just make sure it is pulled flat, because folds throw their own little shadows that the validator reads as pattern. For very young kids, lay a white sheet on the floor and shoot straight down with the child on their back; our guide to baby and child photos for the Cambodia eVisa covers the whole approach, since every minor needs their own photo on their own application.
Wearing a white or very light shirt against a white wall can blur the line between your shoulders and the background, which occasionally confuses the edge detection. If your photo gets flagged and the background looks clean to you, try again in a darker top — navy, charcoal, or any solid mid-tone — so your shoulders read as a clear edge against the white.
Glasses, hats, and head coverings are an expression-and-framing issue rather than a background one, but they come up constantly alongside background flags. Take glasses off entirely, even thin frames, because the lenses catch the window light and throw glare. Remove any hat. Head coverings worn for religious reasons are accepted, as long as your full face from the bottom of the chin to the top of the forehead stays visible and unshadowed.
A flagged background photo is a minor, fixable event, not a rejection of your trip. You get an email that tells you exactly what to re-upload — almost always a fresh photo against a brighter, shadow-free white wall. There is no extra charge to fix it. Free resubmission is part of the all-in price, so you are never penalized for needing a second go at the upload.
Reply quickly with the corrected photo and the 3-business-day approval clock keeps running rather than restarting from scratch. The fastest path is to read the flag, take the new shot using the window-light routine above, and re-upload the same day. Most background flags are cleared in a single retake once you know it was the shadow and not the wall.
When you are confident your photo and background are clean, you can apply for your Cambodia eVisa and move on to the rest of the application. The Tourist eVisa is $80 USD all-in and the Business eVisa is $90 USD all-in, both approved in 3 business days and delivered as a printable PDF by email. Keep a simple photo checklist open while you shoot so you clear every flag — background, expression, framing, and file — in one pass.
