Many times in photographs when an area is so white that there is no detail, the photo is not as attractive. In fact, many times, those blown out highlights don’t work and distract from the main subject of the photo.
But sometimes it works.
Sometimes blown out highlights add to a photograph.
This photograph is of a classic car. I could have easily diffused the light to reduce the highlight. But to me it adds that bit of reality to the photo. Light pouring through the triangle shaped window of an old car.
So remember that blown out highlights can work, if done correctly.
