Using a 5DM3 and a 600EX-RT I'm shooting my subject against a wall and I am getting a shadow cast behind her. I have the flash in ETTL mode and I lowered the FEC to -1. What can I do to eliminate or minimize the shadow of the subject behind the subject?

Thanks.

You could a) move the subject away from the wall, b) light the wall separately, c) use a ring flash.

If your only choice is a camera mounted flash I'd say you need to bounce the flash to get a bigger source of light and maybe move the subject away from the wall some. THIS (external link) guy has a lot of good ideas on how to do that.

A sledgehammer and saws-all will fix that right up! Bye bye wall.

But yeah, if you can't bust the wall down or get the subject away from the wall, enlarge the light source and/or place it in a way that the shadow is minimized.

A light source in front of an opaque object will create a shadow. The only thing you have as a control is to vary the light source, as other have suggested use it in a bounce mode, or get the subject away from the wall. The other option is to make some adjustments in post processing but that can be time consuming. Sorry to say but next time plan your shot better. Even before that do some experimentation, maybe a chair in front of a wall and experiment with bounce angles, distance, etc.

When I took my lighting courses they told me to put my back to a wall. You can bounce the flash off the ceiling towards the subject but I prefer to bounce it off a wall or ceiling from behind me if I can which I call reverse bounce. Or you can can try to get the flash higher up.

Reverse bounce. Image by a member called smorter who I can not seen for quite some time here. Red dots shadows under eyes an nose from light coming strait down. If you bounce forward you can to be pretty far back to angle the light enough.

It is almost impossible to 'get rid of a shadow' once it is cast, you can only add light so the shadow is less contrasty!

All of this and also: get the camera more side-y and throw the shadow out of frame.

Maybe with a lot of cloning which is no fun. Cut the subject out and paste maybe.

Bouncing the flash is the easiest solution.

If reshooting is not feasible, it is possible to at least reduce them to an acceptable level using luminosity masks...
