Focus Recomposing vs. AF Point Selection

In this video, we're going to dive into a half point selection versus focus, re composing when it comes to actually gaining, focusing our images. And I'm going to give you some tips, at least what I like to do when it comes to focusing now, in an ideal world, well, you'd have an f focus point. That's basically over any subject in any place in the frame and it's super accurate. And it works perfectly every single time. But let's, be honest, we don't live in this ideal world, and oftentimes we have twenty, forty or sixty eight points, and none of them are in the area where we want basically are subject to be in focus, because we're not often using just that on ly that center area. Oftentimes we're using very kind of well, more extreme compositions and having the subject's off towards the edges. In addition, many of these outside points are not cross type of points, and without getting into the technical details, basically across type a half point is going to be more accurate. Is going to...

be quicker to focus simply because there are two crossing sensors. So in cameras that give me additional options like it gives me a whole plethora of a focus point. Options. Like my cannon finding mark cruz has sixty one or my defeated two hundred, which has forty something. I always turned them off. Okay, so I turned off, too. So I have my standard f point and my cross type of points on ly displayed as one thing that I'd recommend for you all as well. Now, let's, talk about the center focus point and also focus, re composing. Now, when most people think about focus re composing, they think really on ly of their center, focus point and there's. Good reason for that. That centre a half point. Is the strongest point really on any camera, and this means that if you are shooting in low light situations, if you are shooting and scenes that lack contrast your center a half point is always going to be the best, and people don't realize that low light or scenes that lack contrast doesn't just have to be in places that are dark. You might be shooting in the shade or just out in the day, and you still might have areas of low contrast. For example, if we're shooting well, a bride and a groom and you have a groom or even just a guy in a suit, if he's in a black suit, then there's so much black there, that is gonna lack contrast, your camera is looking for that contrast, and if it can't find it well, then it's going to have issues focusing contrast is tough to find when you have all solid colors. Contrasts is also difficult to find in low light anytime in these situations, I highly recommend centre if point is going to be your best friend for these types of hard to focus situations. But there is a downside when focus re composing, particularly when you're only using the center a half point and that's that when we focus with just a center point general, we have to make pretty broad movement to get our composition correct and that's why in the shot that we're about to take? Well, I'm going to use my outside cross type of points because this is after all, a pretty bright scene they're going to do well and they are cross type of points, then since I don't have enough of them, I'll do minor basically minor adjustments to recompose once I get the closest a half point selected and in focus and they'll do a small adjustment to get my shot. All right, so this what we're gonna do, we're gonna get into the scene and we're gonna get ready so that when the sun comes out guys, we're all ready to go cool, everybody good? Okay, I'm gonna go ahead and stand up with that was like a crowder kid moment was awesome. Okay, so even I'm gonna have you bring your hand up so you're kind of looking at the phone so yeah, kind of cradle it like around there you go that's pretty okay and then turn the phone a little bit more towards me so I could see it a little bit there we go, okay, now the area that I want to focus is really on the best face right here the phone itself is on a very similar focal plane so it's going to be sharp so long as we kind of nailed focus I want to show you guys something if I were to use this center a half point okay, so I'm gonna use the senator have pointing the camera watch how broad this movement is going to focus on her eye and then I'm going to move my frame in the composition okay? That's the composition that was a huge movement to make the problem when you're doing center or focus re composing you this center a half point is that these movements come here really broad if you're shooting at a shallow that the field which we are right now then you end up having a little bit of focus issue either gets going back focused or front focus a little bit because it's hard to keep perfectly still in that movement so what I want to do is switch my point to just the point that's going to be right basically where her here I have one that's kind of really close to here and I all right now watch this when I use this eight point the adjustment is so minor watch I'm gonna focus and recompose I barely moved it all you probably couldn't even see how much I move this is so much of a better technique because it's gonna end up giving you much better focused images. Ok, so let's, go ahead and get everything nailed. It looks like the sun has poked out again. Let's. Go ahead and bring up our main light and I wanted to be pretty hard. We're going to bring it in very close. We want to go for a very strong line. It's gonna have ah, more editorial feel to it versus kind of a soft lifestyle kind of look and that's pretty solid right there that smile a little bit towards that. They're gonna bring the chin a little bit towards me so I can see it. There you go. Right there. Perfect. And bring that hand just a little bit closer. Your face. There you go. Right there. Beautiful. Perfect that's exactly what I want. We're just gonna do a few more shots of this. Some kind of comes in and out to get the perfect shot and that's it. But hopefully I can see the difference now between using the standard eight points election vs focus, re composing, using on ly the center a half point again, my recommendation is you use your outside cross type of points, especially in bryce. Situations like this then focus recompose if you need thio okay, use it first to focus on where your subject is and then move your framing in place if you're in those kind of low life situations or darker situations than yes, obviously, you have to use that center a half point. And then you're gonna have to focus recomposed and just be a little more careful. Take more shots to make sure that they're in focus. That's it for this video. We'll see you on the next one.
