Costco scans all 35mm film and prints chemically.
Penn Camera, Tysons Corner Virgina, prints optically but cannot raise the enlarger head to crop out the Hasselblad film back film clamp bite out of the print.
Samys Camera, Los Angeles and Southern California, prints optically and can raise the enlarger head to crop on request.
Golden Color, Los Angeles, http://goldencolor.com/ 9020 West Olympic Blvd Beverly Hills CA, optically prints and can print VERY LARGE PRINTS including 8"x10". When I want a 24"x36" print from 35mm, I go to them.
