I went to Thailand with my friends last year. It was such an amazing trip!
Here I'd like to share one of my favorite shots during the trip: The night cityscape of Bangkok City from Baiyoke Hotel (84th floor I think)
Equipmentt: Sony A7rII + 25mm f2 Batis
The photo was shot as 8 different shots with same settings, combined and merged together using Photoshop to create a photo with nice light trail while keeping aperture as a reasonable stop. I didn't bring my tripod, so that I use the lens cap to raise the body, pointing down the lens to the city.
I don't remember exactly the aperture, but I'd go with 5.6 or 8. I will share more about the difference between​ using one small aperture vs many larger apertures for a light-trail photography.
Thank you very much.
