I needed to get Canadian passport pictures taken for my renewal application and was informed via yelp talk (thanks, Tiger W!) to go to this little photo shack across from UNLV. The owner/photographer is super nice and knew exactly what I needed when I said I wanted a Canadian passport pic. He reassured me that he has done them before, is a "recommended" passport photographer (by the Canadian consulate in LA), and has all the current specifications on hand. He was quick, thorough, and professional in his work and after about one hour (hung out in Einsteins Bagels while the pictures developed), he handed me the final product. Perfect. (Canadian) passport pictures are $25 for 2.
Much of their business is photo developing and restoration from old photos and from *gasp* film! If I had any old photos to save, I'd come here. As it is, I am very happy with the quality of my pictures and am less hesitant than normal to show them to the appropriate customs authorities because the pics make me look less like a fugitive and more like a person with a neutral facial expression. :)
