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.
Male 1:When critical focus is in play, there's lots of different pieces that you might need to integrate into your kit and into your technique. But one of my favorite techniques for getting critical focus, Rich, is actually probably the most simple. And that's simply zooming in on the sensor so I get a one to one pixel display back here on my LCD or back out to my external monitor. Rich: Now if you've used professional video lenses, you're kind of used to zooming in the lens, setting focus and zooming back out Male 1: Right. Rich: But that doesn't really work on DSR lenses right? Male 1: Right and so a lot of cameras are going to have a zoom function, again what this allows you to do.
Is sort of crop in to the sensor, so you're going to get a much, well, more zoomed in view, a more one to one pixel view, and that's going to help you set critical focus. Let me show you what I mean. So here on the shot, we have it sort of set normally, right, it's kind of a medium close up. But I want to make sure that I have actually tight focus. RIch: Well, it looked good here. Male 1: Well, yeah, of course, everything always looks good there. But I want to be extra sure. So what I'm going to go ahead and do is, just click on this zoom in button here on my Canon 7D, and when I do that, you'll notice that I get zoomed in, here. And one of the things I like to do, is find features of the person, like the nose, the mouth, maybe we'll have the talent smile a little bit. Right? And get some sharp, defined edges.
And once you've gotten in to those points, that's when you can start playing with focus. And making sure that you have it spot on, something like that kind of works. Now right now, you'll notice that I'm zoomed in times five. I click on that again, okay well now I'm like. Rich: It's like a skin carrot. Male 1: Right. Right, we better get some makeup on this guy, right? Click it again and I'm back to my normal view, right. So this is a very simple and straight forward way of checking focus. And it's one of those things, because the button's right on the camera, do it every single time before you record.
And in fact, even if you're using a more sophisticated tool like a follow focus. Rich: Yeah. Male 1: Still not a bad idea to check. Rich: No, I use this as my back up method all the time because I'll chang-, I'll zoom in, I'll punch in. I'll set it. Alright, that looks good. Then I'll look on the monitor. But you always have this feature. So even if your external monitor goes bad or you've misplaced your loop, this is that thing you have no excuse not to check.
