AF Method Shutter And Metering
Alright, so we are on the fourth tab which is dealing with functions with the Live View setting on the camera. So, when you're in the Live View, if you never wanna use Live View, there's some people who bump it and they never wanna use it, they're tired of their camera going into that mode, you can disable that button entirely. You can change the way the camera focuses. We have two different modes, one is a FlexiZone AF which is basically just a box that we get to choose. We looked at this earlier in the class and we can use the touchscreen to choose where we wanna focus and we can position that wherever we want. There's also a Face Tracking mode that will looks for faces and subjects and will try to track that subject as it moves around. In general, it does what I consider a pretty good job, but it isn't a totally perfect job and so be careful about using it in any situation where the subjects are moving too quickly. We have a Grid display that we can turn on, and so, if we wanna see ...
a three-by-three grid or what is this? A six-by-four grid or one with a diagonal which helps us see where the exact middle of the frame is, those can be sometimes handy for lining up subjects in the proper way. Usually, I like to have a clutter-free environment, which is why I'm recommending turning it off. Exposure simulation simulates the final exposure in your image. The LCDs on the back of the Cannon cameras are really good, they're very, very accurate and I use them, in many cases, for judging the overall exposure and what the final image is gonna look like. And this works really good when you're out in the field and under normal circumstances. This is not good if you're working in the studio with strobes because you have the strobes turned off and it's very dark, and then when you fire, the flashes come on and the back LCD cannot simulate that with the flash, and so, it is something that most people would probably wanna leave enabled, but if you do a lot of work in the studio, that would be a good time to disable it. Onto the fifth tab in the Shooting Menu and we have an option, when we are shooting photos in the Live View mode, how the shutter system works and one of the options here in Mode and Mode 2 is an Electronic First Shutter curtain, so let's talk a little bit about how the camera works in the Mirror Lockup mode. So, in the Mirror Lockup mode, the shutter needs to be open so that light can get to the sensor, so that you can see what's going on on the back of the camera. When it's time to take a photo, the camera needs to close the shutter, prep the sensor, and then that shutter opens up. There is sometimes a small vibration, very similar to the Mirror Lockup vibration that we talked about earlier, but this is just the shutter opening very, very quickly, and then the second shutter needs to come in and close and finish the exposure. When we move to an Electronic First Shutter, what it does is it electronically just turns the pixels on, records the image, and then uses the Mechanical Shutter to close it off. And so, the options in here is one and two, will allow you to shoot vibration-free and so, if you are into extreme telephoto photography or macro photography or anytime where you might not have the camera as steady as it could be, the tripod isn't as steady as it should be, that opening shutter may cause a vibration. And so, Mode 1 is the preferred option there, Mode 2 has a delayed shutter which will not return the second part of the shutter, return the shutter to its starting position until you have released your finger off the button, so that could be helpful in a situation where you're trying to be very, very quiet about taking photos. Now, if you are in the studio, the flash will not fire with Mode 1 or Mode 2, so if you're in the studio, you would probably wanna put this on disable. How long do you want the metering to stay active? Eight seconds is the typical time, adjust if necessary. Live View touch control, and so, if you want, you can set this to Standard or Sensitive. And so, if you're wearing gloves, if you have a screen protector or something, it's not picking up your finger movement quite as well, you can put it on Sensitive so it picks it up even more quickly and easily.
