The Netherlands have photo requirements that differ from those required by the Belgium authorities. Each time I have to renew a passport it is always a big gamble to get proper pictures. On many occasions I had to reschedule because the pictures made by a Belgian professional photographer was considered inappropriate. Apparently the Dutch instructions aren't detailed enough for a foreign photographer to make good pictures.
Currently I simply drive to the Netherlands to make those pictures there, but that is not really convenient, and I can imagine that Dutch citizens abroad are facing similar problems.
Are there standardised instructions on international passport pictures or a listing of foreign photographers, that can result in proper foreign (e.g. Dutch) passport pictures?
