i want to do a shooting (fashion) in a professional equipped photostudio in bangkok?

the search didnt bring up something.

does anyone has an idea where i can find such a location?

Try Siam Studio or Bangkok Studio. You should be able to google them. But I must warn you, renting a professional studio with all equipment (real electricity burners, those lamps!) is not going to be cheap. Figure a minimum of 20,000 Baht and up for a day. Alternatively, try one of the many bridal shops you see around. They often do have a smallish studio in the back and might be willing to rent it out. And if you still can't find a suitable place, call the PR department of one of the large advertising agencies (Leo Burnett, etc.). They should be able to give you some recommendations, perhaps even a freelance photographer with his/her own studio.

wow, thank you misterwhisper for that very helpful answer. as 20.000 is a little bit much i will try one of the small photo shops. why didnt i have the idea by myself?

The smaller photo shops around usually have a room or area they use for photos and you can ask to rent, I have used one in the past for 2000 baht for an afternoon.

CREATE IMAGE STUDIO on subsoi 1 off Pridi (soi) 14, Sukhumvit 71; Phra Khanong has a number of different sized professional level studios for rent. Sorry, I don't know the rates.

Pridi 14 is the first right after passing JUSCO supermarket on Suk. 71.
