How to Adjust ISO

We already talked about the main dial we're going to be using this for a number of different features on the camera the s model has the screen on the top and in order to see it under low light conditions they have a little lamp there that you can turn on so that you can see it more easily under low light conditions then we get to our first important button on the camera this is theis o button and a little word for you those of you who are new to cannon on how buttons on canon cameras work yes, I'm explaining how to press a button here, folks all right, so with canon cameras what you do is you press the button and release the button and then you have about six seconds in order to make a change if you wait longer than six seconds, that feature kind of goes dormant and you have to hit the button again and so we'll do what theis oas you'll tap the button and then you will turn the main dial to make a change on the camera, so the options that you have are going to be changing the camera fro...

m one hundred two twelve thousand eight hundred we also have an automatic setting on the camera and so one hundred is where the camera's sensor is designed for taking photos it's where the camera's going to get the best image quality also use some test results here in just a moment and you will bump the esso up according to light and shudder needs and so as it gets darker and as you need faster shutter speeds you will use two hundred and four hundred and eight hundred but there is a cost in quality now there is also an automatic setting where the camera will figure out the correct eso for you and this is a little like automatic driving a car it could be very convenient but if you are very specific about what year you want to be in, you want more manual control and the same is true of photography the more manual control you want to have this is something that you really want to take control of now the final setting the h down at the bottom is twenty five thousand six hundred and you're not going to be able to get to them yes, unless you go into this special shortcut that we have on the screen up in the upper right hand side for those of you who kind of really want to jump in and make that change right now I'm going to get to it later in the class for all of you were like I'm not sure what you're doing don't worry we'll cover it later but for those who want to jump in and expand the esso on this camera toe allowed twenty five thousand six hundred, you could go into your menu setup menu number four item number two in there and you can change it on your camera right now if you really want to so let's take a look at some test results and so I shoot this little cameras on all my test results and I shoot it a different isos in the night crop it and I want to look in really closely at the quality and so just in case you're watching this on a small screen or don't have a good view of it twenty five thousand six hundred looks like gritty sandpaper it does not look very smooth and we've got a lot of noise and bumps and greens especially in the dark areas and it doesn't look very good at twelve thousand eight hundred and so I really can't recommend shooting over sixty four hundred for anything that requires pretty good quality but if quality is important you always want to keep it as low as possible one hundred two hundred four hundred they're all just really fantastic in fact I think this camera is very clean at eight and sixteen and then it really starts getting into the slippery slope of diminishing returns on quality and so it all depends on the type of shot that you're shooting in some cases it's dark you don't have a lens that let's send enough light you need that higher I s so if you need it you got to go with it but always trying to keep it as low as possible if you're trying to maintain the highest quality images is important so on the so I can show you real quickly on my camera on how we do that once again you hit the s o button and you'll see that s o becomes active but if we let it sit for about six seconds it's going to turn off see it turned off on so we got him we got to make action and we could just dial it in by changing this and you can see we don't have twenty five thousand in this camera because I did a factory reset on all the features I wanted my camera the same as yours is if you just took it out of the box and so we can just set it and then what do we do at this point? Well we can hit the set button on the back of the camera that would be one thing we could hit the shutter release halfway down and that always kicks it back into a shooting mode pretty much no matter where you are or we could just let it go dharma dormant on its own and after about six seconds it will just go back into its normal shooting mode right there and so setting the isos very simple and that's going to end up changing the parameters of our shots. So for instance, if I wanted to if I was gonna hand hold a scene in here I might choose eso thirty, two hundred so that I could just set a fashion or speed of five hundredth of a second, an aperture five point oh, I can take this picture. I get uneven exposure as my light meter right here indicates, if I knew that I was on a tripod, which I am right now, I could dial this down tto s o one hundred now I'm underexposed and so now I'm going to change my shutter speed because I'm on a tripod I can use in the shutter speed I want and it will be sharp fifteenth of a second. I'll be very careful about not moving the camera and take the photo and so I have two photos. Let's, play these back one's at a fifteenth at I s o one hundred the next is s o thirty two hundred in one five hundredth of a second, and as faras the image, the way it looks right here is not much difference. But if we were to blow up the thirty two hundred, we would seem or grain and less smooth detail in there. So if I'm on a tripod, I would definitely want to keep it on hi s o one hundred. Okay, so that's our s o and so these air shortcuts that you will see throughout the rest of the class. For those of you who like to jump ahead because I know there's, some of you that are like, I he's going to slow. I want to jump ahead. And I want to get this set right now in my camera. But if you wanna wait, we'll get there eventually.

Great Class! John Greengo is an amazing teacher. I have a t6i for like 6 months and this class helped me a lot. Totally worth the money!

As a student of John's for the past 2 years with the Fundamentals of Photography, the Nikon D3300 and D5500, I recently traded my Nikon D3300 for the Canon EOS Rebel T6i. As always, the training was superb, easy to understand, and I feel better in being able to use a digital camera. The reason for the switch in manufacturers was because of the ease of use of the Canon. I look forward to referring back to the lessons if I need a refresher course. Thank you, John. Your teaching is starting to click, finally.
