In the evening I saw the camera crew posing for bikinis in the hotel, and I noticed that they were using fill lights to illuminate the characters, but the background was very dark. In theory, if taken in the evening or in blue light, the picture will be more beautiful and the background will not be as dark. However, perhaps due to time constraints, the photography team can only shoot on site, but this does not mean that their work can not be appreciated, after all, photography tastes vary from person to person.
