Buildings are illuminated at night to enhance their features and shapes. Nighttime is great to photograph buildings. If you have
to shoot a building at night, the most challenging thing is to get the correct exposure and color balance. Discuss how you will achieve appropriate exposure and color balance. NEED ANSWER ASAP!
Trial and error mainly, but I would at least change the settings for night time and maybe change the white balance to make it look normal (so it isn't yellow or blue). It's mainly up to the person to decide what is correct for the exposure time and color balance.
