Suitable Profiles. Not all subjects are suitable for profile posing. Persons possessing a large hooked nose, receding forehead, or a receding chin, will never make a pleasing profile portrait. A thin face is not a fit subject for profile. Study carefully the features of the subject, and soon your training will enable you to judge at a glance whether or not the subject's features will permit of a profile pose. (See Illustration No. 22.)
Exposure. The exposure for this style of lighting is the same as for ordinary Rembrandt. Give a sufficient amount of time to secure detail in the shadows, as the high-lights will take care of themselves. But, as the shadows are even broader and more dense than in the ordinary Plain Portrait Lighting, fully double the exposure required for Broad Lighting must be given.
Caution. As the camera faces the light when making profile pictures in Rembrandt Lighting, the lens should be shielded with a hood. This is even more important in profile than for ordinary Rembrandt. Unless the lens is shielded a haze is produced on the plate, similar to that resulting from pointing the camera directly toward the sun when making a landscape photograph.
