Before I venture on to reproducing by myself my watercolor paintings and printing my photographs, and hopefully it will happen soon, I'd like to share with you the printing lab in Chungmuro. I have been using their services for years now, I love the quality and how they have a lot of selections for archival prints, they print film, and yes, mat and framing too. Nice and friendly staff is a plus!
PHOTOPIA in Chungmuro. Exit 5. Turn right on the alley with a brick wall (Astoria Hotel is on the left across the street). Walk straight past 3 streets. Turn left on the 3rd street, Photopia is on your left side. Don't be confused of the yellow photopia sign on the right side, that's the old one.
I hope these photos will help.
If you are coming from Humphreys and taking a train, I suggest Pyeongtaek - Seoul. From there you can just transfer to Metro- only 3 stops and my subway app says 3 minutes to get there. Can't beat that! :)
