Subject: Re: multiple photos- making sections lighter
Neither of the examples you posted answer your initial question. You
wanted to know how to blend layers together with advanced lighting
techniques where a person lighting the show was often in frame. The
method I described accomplishes that.

The examples you gave are for tone-mapping images (fake HDR) which is
just a way to compress the contrast of the image so that details that
were in the dark are visible without having the more lit areas be
completely blown out.

It's a decent method for shooting real estate photos, and I've used it
myself for quick and dirty shots. What the guy in the video was doing
was lighting everything in it's most optimal way, in a way that would be
impossible to light without having the lights directly in the shot and
then combining the photos in a way that take the best portions of each
photo to make one shot that lookes better than reality.

If tonemapping/HDR is what you are looking for, use a piece of software
called LuminanceHDR. It's much much easier than using GIMP to do the
same. You can even get decent results with a single RAW image out of
your DSLR camera.
