Here’s a really effective good lighting tip called the Rembrandt
Patch It is called that because this great painter used this
technique to paint his models.

Ok, so you’re outside on a sunny day and you are making a
Video and you have a subject for your shot.

If you place your subject with the sun directly on her with the
Sun coming over your shoulder she is going to squint!! No good!

If you have the sun over her shoulder and hitting you in the face
you will find she isn’t squinting but you will probably under expose
her face unless you can bounce some light into her face to reduce
the overall contrast. (In movies we do this all the time but use
lights and reflectors to help bring down that contrast) I am
assuming you don’t have the tools that I have.

Try positioning your subject so that the sun hits her face but in
such a way that you notice a triangular patch of light under her
eye that is the furthest from the sunlight. You may have to get
hour to turn her head slightly to see the patch but you will see
it.

Think of it as a circle with your subject in the middle and the sun
light coming from somewhere between your camera and 90
degrees to your right or left.

This is the Rembrandt Patch and is the same lighting as the great
painter used on his models. The only difference being that he
used the sunlight (diffused) coming in through a window on the
north side of his studio. He chose this because the shadows would
pretty well stay the same all day as apposed to shooting on the
south side where the shadows would continually move.
