Most rejected home-made photos fail on the background rather than the crop, and usually for one of two reasons: a shadow behind the head, or too little contrast between hair and wall. The required colour is not the same everywhere, since the UK asks for light grey or cream and China for white, so check your own document before you shoot.
A plain, evenly lit, light background with nothing on it. That much is common to nearly every authority. The exact colour is not: the United States asks for white or off-white, the United Kingdom for light grey or cream, China for white specifically, and Canada accepts white or another light colour.
Check your own document rather than assuming white, because the country that wants grey will not accept white and the country that wants white will not accept grey.
| Background problem | Why it fails |
|---|---|
| Shadow behind the head | Reads as a second outline and hides the true edge of the head |
| Textured or patterned wall | Wallpaper grain and brickwork both count as detail behind the subject |
| Coloured wall | Most authorities specify a light neutral; a tinted wall shifts skin tone too |
| Objects in frame | Light switches, picture frames and door edges are all objects |
| Low contrast with hair or clothing | Light hair on a white wall leaves no detectable head outline |
The background rule is really a contrast rule. A white shirt against a white wall makes the shoulders vanish, which looks like a badly composed photo even though the background itself was fine. Wear something darker than the wall.
It is tempting and it is a bad idea. Background replacement leaves artefacts around hair that are obvious at document review size, and several authorities refuse digitally altered photos outright. Re-shoot against a better wall instead.
It varies by country. Plain white or off-white is the most common, but the UK asks for light grey or cream, and some authorities accept any plain light colour. Check the requirement for your document rather than assuming white.
No. A shadow behind the head is one of the most common rejection reasons. Stand well away from the wall, an arm length or more, so the light falling on you does not cast onto it.
Yes, if it is plain, evenly lit and free of texture. Watch for skirting boards, light switches, wallpaper grain and colour cast from nearby walls, all of which show up more in a photo than they do to the eye.
Avoid it. Background replacement is an edit to the image, it usually leaves artefacts around hair, and several authorities explicitly refuse digitally altered photos.
Something that contrasts with it. Light or white clothing against a white wall can make your shoulders disappear, which reads as a poorly composed photo.
