I'm going to be undertaking a portraiture project when I'm in Thailand in a few weeks, and though I will be shooting only for myself, I may in the future choose to use the images in a commercial sense.
What do fellow portraitists do about model releases when you go travelling? And, do you have a specific form you use (and would be willing to share)?
I also prefer portraiture over other topics while travelling. But never bother with release forms. Come to think of it, I don't bother with them at home either. In addition to the language challenge, there is also the need to get the adults' consent when photographing children. If the image captures a large crowd, the problem ballons. Last but not least, asking for release forms may raise unwarranted curiosity/suspicion or request for payments, etc.
Having said that, I recall the following book includes sample release forms. Perhaps even in different languages. But don't hold me to it.
