How to ensure that the window is not exposed when shooting, and the indoor light can be guaranteed?

First, find a high-end camera, more tolerant.

In the second room, add a reflector or artificial light source to fill the light.

Third, for the second shooting, use a corner frame. The first outdoor exposure is correct or slightly underexposed, and the second indoor exposure is normal, and then use fixing solution software (such as universal PS) to do it later. Now there are more and more such products.
