I read a book recently and they were talking about sandwiching photos. Like multiple exposures but not done in camera. They said that you should overexpose both photos by one stop and then combine in photoshop. They didn't go on to say exactly how to do this in photoshop though. I'm assuming layers. But what makes both photos show without looking bled out from the opacity being set lower? Am I even on the right track with the opacity idea?
Pardon my ignorance, but I would think it would give a better dynamic range, so we can use the non-blownout highlights and combine with the shadow details to create a photo that appears to have a wide DR?
