I would like to know if there is an actual video tutorial demonstrating the different built-in flash modes for the D610 and when to use each. I have read several chapters about flash in a couple of books I have purchased, but even so, I remain somewhat confused.
For example, there is "Fill-Flash" and "Slow Synch" (what's the difference?). And when would I want to use rear curtain synch? I am also not sure I understand the physical parameters that cause image ghosting in front of a subject with with front-curtain synch (Fill Flash???) unless the flash fires immediate when the front curtain is first wide open and well before the rear curtain closes) though I think I understand the reason for ghosting behind the subject with rear curtain synch.
So...in short I would like to know how these work (particularly the difference between Fill-Flash and how it compares with Slow Synch) and under what conditions to use any of the other mode choices that are available. My head is thicker than others about this, apparently. I am presently uncomfortable using the built-in flash.

That's is in a nutshell for many - not just yourself. What follows is not a video nor does it confine itself to the pop-up flash but it can get you up to speed on Nikon flash. It did for me. Russ MacDonald is a valued member of this forum.
You may also find it productive to scour the Nikon Speedlights and Lighting forum (under Master your Tools) for ideas.

The D610 has a lot of variation in terms of how a setting works depending on your other camera settings. If you are in one of the scene modes, you get different results compared to Aperture or Shutter priority modes.
The big difference between front curtain synch and rear curtain synch is when the flash fires. This can make a difference for moving subjects, but the big difference is the extent to which the shutter is open to properly expose the background. At the extreme, front curtain gives you a faster shutter speed that lights the subject but the background is dark. Slow Synch exposes for the ambient light - a longer exposure - and then adds some flash at the end of the exposure to light the subject so the background and subject are properly exposed.
The reason you see shadows behind your subject is that the flash is blasting your subject and casting a shadow. The easy solutions are to move your subject away from the background, and to diffuse your flash with a diffuser or bouncing it off a card, ceiling or even your hand.
If you have a trail behind a moving subject, it's because you have a longer exposure that is not freezing subject motion, and then the flash fires and lights the subject. To eliminate the trails, you need a faster shutter speed - typically through raising ISO and using a wider (more open) aperture. If the trail is in front of the subject, it's because you are using front curtain synch with a slow shutter speed and the flash firing at the beginning of the exposure. If it is behind the subject, you are using slow synch or rear curtain synch with the flash firing at the end.

I believe I understand the differences between front-curtain and rear-curtain synch modes and the rationale for why trailing is in front with front curtain synch and behind with rear curtain synch. I don't know why I would want trailing using a flash though I can, perhaps, imagine rear-trailing in certain types of action shots.I still am unclear about the difference between fill flash, slow synch, front curtain, etc. Is SLOW a front curtain synch and if so, does that mean that the shutter is slow and stays open before the flash fires (and if so, doesn't this resemble rear curtain synch)?
So many questions. I'm sorry to be as dense as I appear so soon after acquiring a D610.
I have seen reference to TTL and TTL-BL in several discussions about the flash system,but I don't see those mentioned in the user manual.
If I have bright backlighting, and I want to only fill in lighting for the foreground, it would seem to me that the camera's metering mode would be extremely important in determining 1) the total amount of flash needed, 2) when to flash (slow synch, fill, rear curtain, etc). Right now, I can't seem to come up with a simple rule of thumb to guide my flash choices.
I will study harder and do some experimentation as well. I will probably require some trial and error before I feel significantly more confident than I feel about flash, right now.
Thanks for all the great help and resources. I very much appreciate this forum...it's better than I could even have imagined.

SLOW, by itself, is a front-curtain synch and is referred to in other circles as dragging the shutter. It can also be mixed with rear-curtain synch (dancers in a club setting come to mind). Do you want the subject to float in darkness or to appear in context (& if so, just how much context?). There's no right or wrong here except when you end up doing something you really like or really don't like. Call it taste or artistic choice, that's not important. One of the major points Russ MacDonald makes is the consideration of balancing flash and ambient illumination.

The salient point is made in my manual (D600) in a box at the bottom of the first page of the Flash Photography chapter (same for you - p. 143 in the D610 manual). TTL-BL is used in matrix and center-weighted metering modes and simple TTL is used when spot metering. It's crucial information but remains easy to miss even though it has been promoted from even more obscure locations in previous manuals.

The series of short articles on speedlight flash usage, especially those by Russ MacDonald (Arkayem), may very well help you.
Have a great time :-)

Thank you. Those articles are available for silver, gold or platinum members. I haven't had a chance to review those levels of membership yet, so I'll have to wait on these. However the page is bookmarked on high on my to-do list.
