How to use Off-Camera Flash with Nikon d750 in TTL

Learning how to use and abuse your flash, on-camera or off, is a photography skill that we all embrace eventually.

It’s like a level up on the ladder in the photo toolkit, but so many people are afraid of their flash or think it’s cheating or something.

What using flash does though, is set you apart from the slog of other photographers out in the world.

A huge pet peeve of mine is when photographers brag about being ‘available light’ photographers.

Do you know what else is available? A flash.

What that statement says to me is that you are new to photography and are not equipped to handle difficult lighting situations. You probably rely heavily on post-processing the image and your images look just like everyone else’s.

When you learn how to use a flash, everything changes with your business and your photography. Flash ups your game, big time.

I use my flash in just about every situation. Sometimes it just fills in the subject’s eyes and sometimes I use it to brighten an interesting background.

More often than not, I’ll use my giant (and old-school) QFlash to over power the sun on a bright July wedding day.

One of my favorite tricks is in taking the flash off of my camera for a quick and dirty off-camera trick for dynamic lighting on the fly.

I learned this nifty trick a few years back at a Nikon Speedlight workshop and it has been my go-to flash technique ever since.

So, you are ready to take that flash off of your camera, but you don’t know where to start.

It’s simple!

–>> With the d750’s built-in flash, you can put your Nikon in commander mode to trigger your Nikon Speedlights.

The camera even lets you control the output of light from the flash.

I used to get so annoyed when setting up lighting for the first dance, toasts, etc. and hated having to cross the room to adjust the power of a flash. Then I’d have to shuffle back to where I was going to take the photo to test the light again.

Now I can stay put and adjust each flash as needed.

Getting that light off of your camera is what will really set your work apart from the stream of other photographers and will also help you add light for any situation.

Prior to this commander trick, I’ve used Pocket Wizards (still do) & the Nikon Commander (sold it!).

Another hot tip is to add the commander menu to your “my menu” on the camera for easy access. Now that I use the pop-up flash to remote trigger my Nikon SB-700 flashes, I can hit one button to get into the menu to adjust each flash’s output. Score!

Where off-camera flash with my Nikon really works well is when I photograph my albums and books.

I have one speed light in my living room to fill the background a little as well as add a rim light to outline my albums. The primary flash is in my dining room where I’m photographing the books to fill them in and show off the cover options.

  1. Hi. I can’t stop the on camera flash from firing on my D750 ever when it’s set to – – Can anyone help as I’ve tried everything.

    1. Great question! No, the d750 meters everything for you and balances the light perfectly. The only time it has affected my image has been when I’m taking almost a macro photo using an extremely wide-angle lens.

  2. Do you know if using Commander Mode to trigger an off-camera speedlight also works if the shutter is triggered with a remote, like an ML-L3?

    1. Hey John,
      I haven’t tried that myself, but I’m sure it would work. It’s a line of sight/optical trigger, so it shouldn’t matter what’s pushing the button. Great idea. Let me know how it turns out.
