When on the road as a tourist, I often do not carry a reflector of flash. Now I am at a location with very strong sunlight and I want to take a photo of a companion in front of a nice scenery or building, the classic "we have been here" photo.
With very strong sunlight however, specially at a slight angle, I either get it into the person's eyes and they squint like crazy, or they are in the shade and their whole face is black.
Please note that I do not have aspirations to take a professional photo in such circumstances, but at least something acceptable.
Is there an easy trick to deal with that?
