Hello and good day gnirtS. Thank you for reaching out and for sharing this video you have filmed from the Cheow Lan lake in the Khao Sok area in Thailand. Just a friendly reminder that to please fly carefully and please be aware of your DJI drone's altitude when flying above water. When flying close to the water, the vision system of the said drone will turn off automatically, if the vision system is affected an accident might happen. Again you did an amazing video, please stay safe always and keep on flying.
but, are those colors natural or did you mess with the video in edit software?
Colours are natural. White Balance fixed on sunny, no post processing changes.
Its a limestone lake with lots of mud, silt and minerals (and more concentrated than usual due to the water level being 8m+ below normal due to drought).
