Is it better to use a photographic lamp or a hot shoe flash for indoor photography in a hotel?

It's best to bring a camera light. If it's inconvenient, turn it off and flash. .

As far as the pictures you provided are concerned, the hot boots are flashing enough, the background is mostly ambient light, which is warmer, the color temperature of the characters is basically correct, and the flash is full of light.

I don't know what equipment you use. .

Suggestion:

Canon 6D or 5D is equipped with 580 or 600 flashlights to accomplish this task. .

Nikon D700/D6 10/D800 can also be matched with SB800/SB900.

If you want more lighting effects, you can use more than two hot shoe lights, flashing lights to turn it off, reflector/umbrella and a small soft box to achieve the effect. The most important thing is to pay attention to the light ratio and parameter combination, give priority to portraits and give consideration to ambient light. After all, the main performance here is the environmental portrait. .

Good luck!
