Join Richard Harrington for an in-depth discussion in this video Controlling the camera with a smartphone, part of Shooting a High-Dynamic Range (HDR) Time-Lapse Video.
There are so many different ways to control cameras these days, because so many people have gotten into time lapse. One of my favorites is thing called Trigger Trap, and what's great about Trigger Trap is it's very versatile. It really comes with two pieces, one piece goes to your phone. And they make this for a wide range of smart phones. Most of them, though, go right in the headphone jack. And the phone will send out a series of controls over that headphone jack. Then it connects to a dedicated cable, and you can get multiple ones of these. The benefit of this cable is that this goes to your camera.
Well notice by selling these pieces separately, they give you greater flexibility. You could one of these and a bag full of these for multiple devices or if a piece goes bad, you just order the part that you need. Alright, I've got that connected and I'll put it into the side of the camera here. Pretty easy. Most cameras will have a port over on the side of the camera where you connect a remote control. And now I'll put that in to the bottom of the phone. Now one of the things I recommend is quit any other applications you have running that might push you an alert.
In fact, it's a good idea to even turn off alerts on your phone if possible because anything that sends a beep could get in the way of the app running. Remember, what's going to happen here is as you're doing that it's going to make some sounds, and those sounds might accidentally trigger the camera in a way that you don't want. Alright, I'm going to go to Notifications and just turn those off for a second. That's the Notifications Center, and let's just go to Do Not Disturb and invoke that. So now I'm not going to get anything else to the phone, I'm just using the phone as a device.
So, no phone calls No emails, but hey, that's okay. It's alright to unplug every once in a while. Okay, with that done we can now launch Trigger Trap. And this is going to give me some more advanced controls. Now, I have the ability with this to do a long exposure HDR timelapse. To do this, I need to put the camera in BULB mode. BULB mode is going to be a manual exposure tied to the release when the button's pressed. No timing, no bracketing. It'll be done by the camera itself.
This is just one way of shooting in HDR. Now before we go too deep into BULB mode, we'll actually try this with a few other options here and do some test shots as well. But you get the general idea. Remote control device, connected cable and unplug so the smart phone is ready just to do this. Alright, let's head back over and check on our Nikon camera. Make sure it's up and running. And then i'll come back here when the sun's a little bit better and we'll this started with a long exposure each DR time lapse.
