This weekly course covers the most common questions videographers encounter when shooting and editing with DSLR cameras, from choosing a frame size and frame rate to understanding moiré. Authors Rich Harrington and Robbie Carman will also help you understand the impacts of compression and the difference between cropped (or micro 4/3rds) and full-sized sensors in cameras, and much more. This continual FAQ guide is a handy way to find the answers to the questions that plague you the most.
Rob: So I'm here with DP Jim Ball. And Jim in an earlier episode, we took a look at the operation of a jib. And you made it the point several times, you know, you kind of want to take your body and your hands out of it. Not touch the camera, that kind of stuff. And often times the camera could be 10, 15, 20 feet in the air. What do you do if you have to make an adjustment to a parameter on the camera? Jim Ball: Well if I have no other choice with fancy technology, I just have to stand up on a ladder and, and reach on my tippy toes, which I've done many times. Rob: Right. So, you know, of course there's the manual adjustment, but, you know, these days there's sort of remote control or sort of tethering options that we have for the camera that can put control of the camera in a device like an iPad rather than you having to get up on a ladder or push buttons manually in the back of a camera.
And we have one of those devices here called a CamRanger. And in an earlier episode we used the CamRanger for tight spaces, but it's actually a perfect situation for an example like a jib shot. So what we could do is position the jib and if I go, oh, you know what, I want to be able to change the f-stop, I can simply click the aperture value here, and say change it from F4, it will change it up to F5.6. And you'll notice that the shot actually got darker. And it updated the aperture of our actual shot, what you can see on the screen there. So without having to have our hands on it, this is a very viable way to control all the parameters of your camera.
The other cool part is that you can actually see a live preview. So Jim, if you move the camera there a little bit, you can see that I'm actually updating here on screen. Now, there's a slight, moderate delay on the actual images that you're seeing on the screen, but for all intents and purposes, it's just fine because what you're really trying to do with an app like this is control and tether the camera. And Jim, have you seen these devices, and devices like this and others, in more use in the field? Jim Ball: Yeah, I mean not just for for jib arms and other remote possibilities, but also small cameras like GoPros and little hard to reach cameras.
You know, there's all, car mounts, all kinds of things where there seems to be more and more options with newer cameras for Wi-Fi compatibility. And then actually these little specifically targeted sensors that work with just one device. So yeah, there's lots of applications for this stuff. Makes things safer, makes things happen quicker. I mean, all kinds of options. Rob: Yeah, and thing about these as well is that you know, couple of years ago they would've probably been in the multi thousand dollar range for a setup like this,. These days you can find these units for around $3 to $500, and they're really simple.
Just an app that goes on your, your mobile like an iPad, and then sometimes device like this. This particular one just plugs in USB to the camera to take complete control of it. So when you're out there doing shoots like with the jib, or you need other situations where you want to have remote control of the camera, consider a tethering option like the CamRanger. I think you'll find it really valuable.
