Hello all, just saw this picture on Instagram and was wondering how they got this effect and what the effect is called? Double exposure?
There are several ways one could get results similar to the one in your example image. Among them:
Since the subject's eyes are opened by differing amounts in the example you posted, at least two exposures were used to make that image. Whether they were combined on a single frame of film before being developed, combined by printing two negatives to the same piece of photo paper in a darkroom, combined digitally using a camera with a "double exposure" mode, or outside a camera using post-processing applications, etc. would be very difficult if not impossible to ascertain.
