In several years of the last decade Bangkok was even the most visited city in the world!
Very nice to see that as a film photographer you are "safe" there concerning lab options: 18 labs, holy moly, that is quite a lot
I remember a photographer friend who visited Bangkok about two years ago and wanted his films be developed there: He found 10 labs at that time.
So it looks like the number of labs has almost doubled in a very short time.
Sign of a powerful film resurgence there.
