I am a beginner with Nikon D 7100 and Speedlight 700 I want to set the camera up to fire up the speedlight off camera I think I have to use the internal flash in the camera to fire off camera speedlight 700 flash But I only want to use the light from the internal flash to fire the speedlight. I do not want he light from the internal flash to light up on the subject.
I think there is a place in the Nikon D 7100 I can set this option up - But How - and where ?
English is not my mother tongue. I hope anyway some of the users in this forum understand my question and will have the trouble to give me some help.
In the Bracketing/Flash menu, go to e3: Flash Cntrl for Built-in Flash. Select Commander Mode and set the Built-in Flash to --. Set the Group A to TTL and Channel to 1 (default values for the SB-700). Turn the SB-700 on to Remote and it should work (as long as the SB-700 is still set to Group A, Channel 1).
Once you have them talking to each other, you can start playing with the settings. For more information, check the D7100 manual starting on page 246.

Along with Brent's advice on how to set it up, keep in mind that the internal flash trigger signal to fire the SB700 occurs when the shutter is open.
The trigger signal is at reduced power and generally the subject is far enough away that it doesn't contribute to the exposure. But under specific circumstances ( if the subject is close enough and ISO high enough) the built in flash might contribute to the exposure even though you set -- in the menus.
There is a Nikon part available (SG-3IR) that will block the visible light. But all I do usually is just hold my hand in front of the built in flash when I think it may be a problem (when I use the CLS wireless my camera is usually on a tripod so my hands are free).
When I set the Speedlight 700 to remote and The camera to commander mode (-..-) It works very well. But if I want to adjust the light compensation it can only be done on the camera's custom menu. Am I right here or do I overlook something ? Thanks in advance - Frank

Frank, the number of combinations are vast, but primarily I believe it depends on how you have the Group set.
If set to TTL, then the flash button can be used to set an overall flash EC, as well as going into the Custom Menu's and setting it there. But if you have the Group set to M (manual) then I believe you can only set power up by the Custom Menu's.
If I'm off base here I'm sure someone will chime in to correct me.

Correct. The SB700, being set to CLS remote, may be adjusted by a Commander using the same Group and Channel (in this case the camera) and by nothing else. The advantage would become apparent when trying to achieve reasonable lighting ratios from several different units, some of which might be tedious to access and adjust individually.

Over in the 'Light and Exposure' forum someone asked about settings to avoid flare on shiny surfaces. In my reply I mentioned the concept of 'Family of Angles' and Specular reflections.
As an example of what Hendrik and I are referring to, I provide this example.
That shot was taken by me in response to a challenge Martin Turner threw down in the "Glamour & Portrait, Commercial & Studio' forum in how one would present a glass half full (Photoshopping allowed).
From reading 'Light, Sience and Magic' I knew that the glass would have a HUGE Family of Angles and any light source in front of the glass would create specular highlights that I wished to avoid. If I had not blocked the built-in flash that I was using as commander for my two SB800's, I would have had an ugly specular highlight on the front of the glass.
So while the built-in flash generally doesn't contribute to the exposure in some cases, it can and will in others.
