Siem Reap will see a nice weather (can be a little hot at midday) at this time of the year, evening will be cool (maybe down to 15-17ºC at night).
Bring your best camera with a few lenses and Flash cards, your laptop and a card reader… that’s it. Hopefully by now you are getting in the place in your mind and you are already researching on the internet what kind of story you will work on! Good! but we’ll be waiting for anyone trying to surprise us with something new.
