You actually have a choice. You can go to the drug store or your local auto club office and have your US Passport photo made, or you can go to Newsome's Studio in Carrollwood (North Tampa).
Be aware though, that there will be differences. For instance, the cameras and lighting used by non-professional photographers will vary greatly. They are largely very simply "point and shoot" cameras using "auto" settings that produce a low resolution image. The lenses on those cameras cannot be manually focused, and if the settings have any manual availability at all, the operator likely has little to no experience with it, meaning if your image looks orange, they may not know how to fix it by changing the settings on the camera (yes, this is a very common problem).
At Newsome's Studio, you're being photographed by a 30+ year professional who uses only the very best photography equipment, camera, and lighting available. Face it folks, you're going to be looking at that image for 10 years... TEN YEARS! Get it done right. Go to Newsome's Studio at 10012 N. Dale Mabry Hwy, Suite 219, Tampa.
