Hyperfocal Quiz and Focusing Formula
Hyperfocal Quiz, alright. Let's think about where you might need to focus. If you had a 28mm lens, and I'll just have you hold up your answers here, this is gonna be total guessing on your part, because this is a hard one here. If you have a 28mm lens @ f/22, f/22, okay that's a lot of depth of field, where would you focus at to keep everything in focus? Alright, so 28 is kind of your standard basic wide-angle lens. 22 is gonna give us a lot of depth of field. Do you think it's 1.5 meters is where you would focus? Three or six meters? So let's hold up your answers, one, two, or three, everybody raise your hands up, and we see lots of two's, we see some one's and some three's, and the actual answer is you would focus a meter and a half out alright? And that, that's far enough that it would get you from 70cm all the way to infinity, alright? Alright, let's try this again. Now with a 20mm lens, even more wide-angle, but it's f/16, not f/22. So where do you think you're gonna focus? A half...
meter out, one meter, or two meters? A second to think. And raise your answers up. I see some two's, lot's of two's in here, and the actual answer is two, nice job folks, you are learning this quicker than I expected. Or you're guessing really well. Okay, and so the question that you really have when you go out in the field and you line up your shot, your question is well, where should I focus? Because I want the flowers in the foreground, I want the mountain in the background in focus. Where do I need to focus? And that's kind of the tricky thing. So if we were to go back to that quiz. Let's go back to our quiz. And so we had a 28mm lens at f/22. Now, the correct answer was 1.5 meters, and if you focused there, you get everything from 70cm to infinity in focus. Now notice that 70 is about half of this. 70 times two is 1.4 meters. So where you focused at, 1.5 meters, about half that distance was the nearest point of focusing. And so we can reverse this out in the field, and we can ask the question, what's the closest thing in the photograph, and we can double the near point. So, what is the closest thing to us. One of these flowers down here in the foreground. How far is that from the camera? You can't tell, because you weren't there, but I'll tell you that it was about three and a half, maybe four feet. We would then focus at around seven or feet back in here. That's where we focus, and it will hold everything from half that distance, all the way to infinity. There has been another rule of thumb that has said focus one third into the frame, and that doesn't work, depending on your composition of where you're horizon is in the frame. This is a much more accurate. This is still not perfect alright? I'm not saying this is perfect, but it's really close, and it's close enough to get things very close out in the field. And so another example. Where am I gonna focus? Well what's the closest thing I want in focus, well, right down here at the bottom of the frame. And then I just kind of have to estimate. You have to be able to estimate two, three, four, five feet away, and then I'm gonna look for something that, well, what's twice the distance away? Well, it's gonna be something up around here. And that's where I'm gonna focus the lens. So I'm gonna either tilt the camera down, or I'm gonna select a focusing point, or I'm gonna manually focus on that particular area. What's the closest thing in the frame? In this case it's very close to the camera. It's inches away from the camera, but it's right down there at the bottom of the frame, and then in this case it's a little bit higher up, because of the composition of this particular case. And so this is a really easy formula. What's the closest thing, double the distance. And if you have a focusing scale on your lens, you can actually look and go okay, well that's at two feet, I'm gonna go to four feet. So that's one of the reasons why it's really nice to have a focusing scale on your lens. And some lens have it, some lens don't. Here we have a 100mm macro lens, and here we have a 50mm lens. The 50mm does not have a focusing scale on it. That's gonna be really hard to do, because you're gonna have to like guess where things are, just by turning it around. So, one of the other benefits of the slightly nicer, higher-end lens.

Love love all John Greengo classes! Wish to have had him decades ago with this info, but no internet then!! John is the greatest photography teacher I have seen out there, and I watch a lot of Creative Live classes and folks on YouTube too. John is so detailed and there are a ton of ah ha moments for me and I know lots of others. I think I own 4 John Greengo classes so far and want to add this one and Travel Photography!! I just drop everything to watch John on Creative Live. I wish sometime soon he would teach a Lightroom class and his knowledge on photography post editing.!!! That would probably take a LOT OF TIME but I know John would explain it soooooo good, like he does all his Photography classes!! Thank you Creative Live for having such a wonderful instructor with John Greengo!! Make more classes John, for just love them and soak it up! There is soooo much to learn and sometimes just so overwhelming. Is there anyway you might do a Motivation class!!?? Like do this button for this day, and try this technique for a week, or post this subject for this week, etc. Motivation and inspiration, and playing around with what you teach, needed so much and would be so fun.!! Just saying??? Awaiting gadgets class now, while waiting for lunch break to be over. All the filters and gadgets, oh my. Thank you thank you for all you teach John, You are truly a wonderful wonderful instructor and I would highly recommend folks listening and buying your classes.

I don't think that adjectives like beautiful, fantastic or excellent can describe the course and classes with John Greengo well enough. I've just bought my first camera and I am a total amateur but I fell in love with photography while watching the classes with John. It is fun, clear, understandable, entertaining, informative and and and. He is not only a fabulous photographer but a great teacher as well. Easy to follow, clear explanations and fantastic visuals. The only disadvantage I can list here that he is sooooo good that keeps me from going out to shoot as I am just glued to the screen. :-) Don't miss it and well worth the money invested! Thank you John!

Wow! John is THE best teacher I have ever had the pleasure of learning from, and this is the most comprehensive, eloquent and fun course I have ever taken (online or off). If you're even / / interested in photography, take this course as soon as possible! You might find out that taking great photos requires much more work than you're willing to invest, or you might get so excited learning from John that you'll start taking your camera with you EVERYWHERE. At the very least, you'll learn the fundamental inner workings and techniques that WILL help you get a better photo. Worried about the cost? Well, I've taken courses that are twice as expensive that offer less than maybe a tenth of the value. You'll be much better off investing in this course than a new camera or a new lens. I cannot reccomend John and this course enough!
