German passport photos are the same size and specs as the UK and France. All three call for two 35x45mm images taken on a light gray background with a head size of 32-36mm.
Because (like most of the planet), they're measured in millimeters, you're not likely to be able to get them from your local drug store or auto club. The measurements are very precise and must be custom cut and sized correctly in Photoshop to meet those requirements. In short, you really have to go to a professional photography studio that specializes in foreign passport photos.
Newsome's Studio of Photography, located at 10012 N. Dale Mabry Hwy, Suite 219, Tampa (Carrollwood), has been providing passport photos for foreign citizens for several years. Having successfully done passport photos for over 75 countries and counting, we've yet to find a country's specs we couldn't create.
By appointment only, please call 813-968-2810 and schedule your 10 minute appointment to update your foreign passport photos.
