Depth of Field Camera Features
For the SLR users, one of the benefits of many of the cameras out there is that they have a depth of field preview button. When you look through the camera, the manufacturer wants to give you the best view possible. So it opens up the aperture to the maximum aperture, so that you have the brightest viewfinder, so you can focus the most easily. The problem is that, if you're taking a photo, and the actual photo is f8, you don't get to see what your depth of field is until you press this button. And so what's gonna happen is that, normally, when you look through the viewfinder, you see with as shallow a depth of field as possible. And the reason for this is, number one, it's the brightest possible viewfinder, so you have easy light for focusing. And it's also the shallowest depth of field for easy manual focusing. When you press down on the button, which is in various places on cameras, it stops the aperture down. And you will get a very dark image to look at. And what happens for most p...
eople is, they press the depth of field button, and then they say, it's really dark. Keep your eyes, let your eyes adjust for the darkness, and then you will eventually start picking up, hey, look at this, I can actually see the sharpness down here. Now this used to be one of those high-end professional features on cameras in the 70's and 80's. Nowadays, a lot of times, I would tell people, just shoot a photo and look at it on the back of the camera to see if you've got the right depth of field for what you're trying to do. But this is still helpful under bright light conditions. Remember, I said, with the SLRs, you have to view on the back of the camera, and under bright light conditions, it doesn't work very well. So this is a feature I have on my cameras, but I don't honestly use it that often. Every once in a while, when I do need lots of depth of field and I'm in bright sunshine and I want to get a preview of it, it's a nice tool to have. And most SLRs have them these days. One of the things to be aware of, for the SLR users, and this is gonna be also one of the little bragging points for those of you with mirrorless cameras about one of the benefits of mirrorless cameras, downsides of the SLRs, is that the SLRs have focusing screens in them. And they've had focusing screens in them for a long, long time, it's part of their system. But these went through a change when we developed the auto-focus systems and they were added to the cameras. And the manufacturers were faced with a technological problem, and they had to choose one direction or the other, in designing and building these screens. And the choices that they had, was to develop a screen that was really bright or a screen that was really accurate. And both of those things are really important. And they decided that they wanted to have lenses like an 18 to 55, 3.5 to 5.6 lens, which is what we call a fairly slow lens, it's a fairly dark lens. And they've decided it'd be more important to have brightness than accuracy. And so we can use a wider variety of lenses in our cameras, they've kind of dumbed down the focusing screens in our cameras, and they were no longer accurate for lenses that are faster than 2.8. And so, if you have a fast lens, like an 85 1.2, a 25 1.4, a 35 f2, what you see in the view viewfinder is not the depth of field of those lenses. The depth of field is that of about a 2.8 lens. And so when you are critically focusing, and this is really important for somebody who has an 85 1. and is doing portrait photography, focusing on someone's eye, it's not quite, it's in the right place but it's showing you more depth of field than you're actually going to get in the final photograph. And so, for anyone that has a really fast lens, they have to be concerned about this. And so basically, 2.8 is the cutoff. If you have lenses faster than 2.8, be aware of this fact. There's not much you can do about it if you're using the viewfinder. And so you have to have your focusing calibrated really right. And this is one of the reasons why I do not like to manually focus with my camera with my lenses that are faster than 2.8. There's not that many lenses that fall into that category, but you have to be very careful about manual focusing in those situations. You can still do it accurately, it's just challenging. And this is one of those things that's nice about mirrorless because mirrorless will show you the actual depth of field. And various mirrorless cameras work in different ways, but some of them will show you the actual depth of field you're gonna get, as you change that aperture back and forth, which is really nice. You can see it in the viewfinder, you don't have to press any buttons another advantage of the mirrorless cameras.

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!
