It helps to have something to steady the camera on, and that becomes part of the challenge, too. Usually I'm walking and have to make do with whatever happens to be available: a table, against a pole, leaning on a building or just setting the camera down on a motor scooter seat and hoping the owner doesn't think I'm up to no good. Maybe I'll break down and buy a simple tripod there one of these times.
Here are a few time lapse night photos, casually grouped together as "friends having a late night meal". The top image is a view of people eating outside a 7-Eleven below the Chong Nonsi BTS station, sort of across the street from the Om Yim Lodge.
Below are folks sitting at the metal tables of a sidewalk eatery on Second Road in Pattaya, somewhere along about midnight one night. Below that is an image of friends having dinner beneath the festive lights in Pattaya at the now-closed Amor Restaurant, where I've enjoyed several leisurely dinners myself.
