Jack in Florida asks:
When I photograph the exterior of a house, I generally like to have the interior lights on especially if there's impressive chandelier or other lighting features inside. After doing this for over 10 years, I got a complaint from a new agent that she did not like the lights being on in the interior. So I had to Photoshop the lights off. Is there a general rule for leaving the interior lights on/off when taking photos of the exterior?
There are few, if any, general rules in this business. You can find interiors photographers that will argue either way.
Many will argue that a room looks more inviting with the lights on. I suspect that the reason many photographers turn the interior lights off is the issue of controlling the white balance. But I find that if you use even one small flash, the color balance of the flash dominates the room, minimizing the effect of mixed colors from the room lights.
The argument for turning the lights off is frequently that the ambient lighting from the windows will sometimes be more important than the artificial lighting.
As far as when to turn the interior lights on for an exterior shoot, it depends on the time of day. Twilight shots are very beautiful with the lights on, whereas exterior shots on a bright day don't need interior lights on.
