In a previous post, I wrote about using black flags in interior photography. In this case, I did something similar to block light. That’s me up there holding a reflector to block light from a small bathroom window. Without it, harsh light was spilling into the bathroom.
You can see in the image above how light from the window is hitting the left side of the frame and even parts of the sink. By cutting out the harsh light I was able to get an even exposure for the bathroom and blend it with the final image.
