Is it possible to take a photo for a British license at home?
I decided to take photos at home to avoid wasting time in a studio, but I faced many small problems. Everything seemed simple: I found a light wall, put my phone on, and turned on the timer. But when I checked the shot, it turned out that the background was slightly uneven, the shadow from the chin was still visible, and the face was too dark. I redid it several times but wasn't sure the result would work. Ultimately, I decided to use a service that automatically edits the photo and adjusts it to the requirements of https://photogov.net/documents/gb-driving-photo/. You upload an image; it removes the background, corrects the head size, and formats the file. It was easier than having to do the retouching manually.
In fact, it is quite realistic to take a photo for a driver's license at home, if you follow a few simple rules. The main thing is to find a good source of natural light (a window in the daytime, but not in direct sunlight), use a tripod or an assistant, and make sure that the background is really homogeneous. The problem with colors is also important: for example, warm lamp light can give a yellowish tint to the skin, and this is already a risk to get rejected. You can check the size and framing of the photo in online tools, or even better, compare it with samples on the DVLA website before uploading it.
