3 Primary Types of Autofocus

And this video we're going to talk about the three different types of auto focus that you have available now depending of course on the brand of camera they might refer to these different auto focus modes in different ways but really they are one and the same and to be honest in my opinion there are really only two modes because the third mode is generally just a hybrid of the other two out of focus modes so we're gonna talk about those now the first mode that I want to mention is single shot or single servo now on icon they refer to this a single servo on can they refer to a single shot on other brands and makes the refer to as the things but all this is is that when you depress the shutter halfway it focuses once and only once when the shutter is fully depressed from that halfway point then the shots actually taken but the focus doesn't change now generally this little two step action is really kind of seamless and when you're taking shots you don't notice if you've fully press down ...

the shutter all the way it just takes the shot as soon as it's ready and you don't notice that it's actually focusing and shooting in two different steps but it is and the great part about that is that we can actually use the two step process to set up a sort of get our focus and then we can recompose the scene how we like and that was like a no looker right there. All right, so you can focus recomposed the scene depending how you need and then whatever want to do, we can shoot it right afterwards. Now, of course, we do have some tips for you on this, but that's, the benefit of single shot is that you can focus with that halfway down, you can lock the focus and then take the shot whenever you need single shot works incredibly well in static type situation situations like this where I have yvette sitting here and we're going to do a couple portrait's were basically she's not moving situations where movement is occurring perpendicular to the camera, we're going to show you that in just a moment now, the second of these modes is known as a servo or continuous servo again, canon calls a servo nikon calls it continuous servo, but they're both operative same way. Essentially, what happens in the auto focus modes is that when the subject is moving, the camera is continually focusing over that subject over the a f point that you're using. So if I placed my half point right in the center of the frame, when you do that now. And I have it over yvette's face, then as long as I have, the shutter halfway down is going to continually focus all the way to the point where I actually captured the image you might be asking, well, why do I need that when events holding completely still and I don't ok, so we don't use auto several modes? Well, when we're shooting ports like this, what you would do is he would use it in situations where your subjects are moving basically towards or back from the lens. Okay, so if they're coming closer to you or they're moving away from you, these situations where a server would come in really handy because you want the camera to continually focus on the subject on right until that point of capture. All right, so we're going to show you guys in real world, basically, we're going to demonstrate all these things. Oh, I almost forgot. What about the third mode now our third mode auto servo or a focus? Whatever your camera brand calls it, this is really more of a hybrid essentially in this third mode, what you're allowing the camera to do is to choose between single shot or between a servant mode, so essentially decides for you based on whether the subject is moving or not now, obviously you're gonna probably know why? I would recommend not using this, because, really you don't know what the cameras doing in that situation. You don't know if it's using servo. You don't know if it's using single shot. You're letting the camera decide for yourself in any time we give the camera that control, we're going to get kind of wonky. Settings were gonna get kind of walkie focus where we don't really know what's happening. So I always like to take that control back. I don't use that third mode. I'd highly recommend. The first two that we talked about, and what we're going to do is just move into shooting right now so we can actually demonstrate.

Class Description

Learn how to create, edit, and share stunning digital images.

To a photography beginner, the gleaming complexity of a new camera seems to demand an arsenal of expensive equipment and a long legacy of training. This is a common misconception – beautiful, professional-grade shots are within reach to any with a mastery of the basic mechanics of photography.

Join Pye Jirsa of SLR Lounge for a thorough, practical exploration of the fundamentals. Photography 101 teaches you how to use standard, inexpensive equipment to:

  • Explore the inner mechanical workings of your camera
  • Learn how to recognize good light and modify it to your needs
  • Make the elements of manual mode - aperture, shutter speed and ISO - work for you
Take advantage of the flexibility and control offered by your camera’s manual mode by shadowing Pye on 5 days of shooting at 8 different locations. You’ll learn how to capture both crisp action shots of moving subjects and classic portraiture with posed models. You’ll also gain a sense of what makes a great photograph, and how to mix professional staging with candid, humanizing moments.

You will walk away from Photography 101 with SLR Lounge's Pye Jirsa as a better photographer, and you’ll have the creative and practical skills to create, edit, and share stunning digital images; all with no more gear than you started with.

I watched this class "live" and was simply amazed at the amount of information Pye covered. Yes, he talks a little fast, and since I was streaming the class I couldn't stop it to review anything, but this guy really knows his stuff and explains it very well so I absorbed quite a bit. Bye is enthusiastic, clearly enjoys his craft, and delivers excellent information to students in a light heartedI and fun way. I think some reviewers are a bit harsh about his humor. Lighten up, people! His examples and the additional information his co-host provides are very worthwhile and you can tell the course was well thought out. I plan to buy the class to help me get back into DSLR photography.

I really enjoyed this class. I am not a beginner, but there were still things I learned here that I found helpful. I really enjoy learning from Pye. He is quick, gets to the point and doesn't spend a lot of time going over and over the same point. There is a wide variety of things that he covers, so really something for everyone. I would recommend purchasing this class if you want to understand your camera better, improve your technique and start taking better photos.

I have tried to learn photography myself via the internet / YouTube but always felt like I was missing something in my foundation. Sure I can zero out my meter...but why? How do I know the settings I've selected are the correct ones? I've been circling this drain for a year until this course. WOW! Pye has SO MUCH information in every video. He doesn't just stand in a classroom and talk, he's out in the field actually putting his settings into his camera, talking about why and why not and then shooting. He's hands on the entire course. You don't just hear him, you see exactly what he's doing! I'm a visual / listening learner and this is my eureka moment! Thank you Pye! Watching the Exposure video and how you changed the settings yet maintained the exact same exposure was mind blowing. Awesome course! I would recommend this to anyone new to photography or anyone that feels like they don't have all the info.
