There's a button on the right-hand side that you can press to open the camera app. With the camera app open, the shutter button will also let you take pictures. It's a two-stage button as well, so you can push it down halfway to focus it before taking the picture.
'Burst mode' lets you take lots of pictures really quickly, so that you can go through them and find the best one. Using this mode, for example, helps you get a shot with no one blinking or looking away.
After choosing Burst mode in the settings, you just need to press and hold the shutter button and the camera will take pictures until you let it go. Make sure you go through them afterwards though, because you'll have your space taken up by lots of unwanted pictures otherwise.
To use the self timer, open the settings menu and choose it. You can pick from a delay of 2 seconds or 10 seconds. When you press the shutter button, the timer will countdown before it takes the picture.
'Launch and capture' is something that lets you quickly open the camera app and take a picture straight away. It can be really useful if you need to grab a picture fast. To use it, go to the settings menu and choose the 'Quick launch' options.
There's two ways to focus the camera, either by tapping the person or object you're taking a picture of, or by half-pressing the shutter button.
To zoom, you can either pinch the screen, or use the volume buttons.
Here's a full list of the settings that you've got.
'Superior auto' mode lets the camera choose the settings automatically. It picks up on light levels and movement to choose the best way to take the picture. You'll notice a small icon that changes, next to the mode button, depending on what settings it's picked up.
'Manual' mode lets you choose all the settings yourself. This means you can choose scenes as well, like night, landscape, macro, sports etc. It'll also let you choose what size picture to take, from as small as 2MP, to the full 20.7MP.
Being able to record videos in 4K is quite new to phones. The standard resolution is around 2000 pixels, but 4K is around 4000 pixels. It means that even if you can't find a 4K screen to watch the video on, you'll still see a lot more detail in the video on a normal HD display.
'AR' or 'Augmented reality' means you can put fun features into your pictures. 'AR fun' mode lets you tap to add effects, while 'AR effects' lets you choose bigger effects that will automatically come on the screen. That means you'll be able to photograph your friends playing with dinosaurs, sharks and more.
To be able to use multi-camera, you'll need a few friends who've got Xperia phones as well. You'll all need to open the multi-camera mode, and then use Bluetooth or NFC to connect them together. If you all record a video, the phone'll combine them together to make one shot.
'Face in' lets your put your face into the picture you're taking, by using the front and rear cameras at the same time. It's great for family shots, to make sure everyone's in the picture, but it's also a cool way to put yourself into the background of the picture you're taking.
The Z3 lets you blur out the background of photos, giving you a cool effect like you get from a DSLR camera. It means that the object of your picture is more eye catching, because the background is blurred out.
These are some of the other modes you can use with your camera.
