on either side of the moment when you capture the photo, so anything moving in the image you photographed, such as water flowing in a stream, seems to move when you press and hold the still photo.

      The iPadOS 15 update to the operating system adds many features, including (but definitely not limited to)

       Performance enhancements: Apple promises that iPadOS 15 will increase the speed and performance of your iPad, including older models going back as far as iPad Air 2. From apps to keyboards to taking pictures, everything gets a speed upgrade.

       Focus: Think of Focus as an extension of the Do Not Disturb feature. You can customize a focus to filter notifications based on what you’re doing at the moment. The default focus modes are personal, work, and sleep, and notifications are filtered based on their settings.

       Safari: iPadOS 15 gives Safari a whole new look and makes navigation easier. Tab groups are a welcome new feature that allow you to group your open web pages any way you like.

       Maps: Like Safari, Maps got a nice interface overhaul. Three-dimensional items like mountain ranges, buildings, trees, and more are rendered to make them more lifelike, making it easier to follow directions and recognize locations. A more detailed driving map is also a great enhancement.

       FaceTime: You can now schedule calls using FaceTime (this one falls into the “it’s about time” category …) and send links to participants. Also, the interface got a refresh, and the enhancements to sound technologies make hearing call participants much easier.

       Siri improvements: Siri just keeps getting better. Siri can now speak in more natural tones and cadence, thanks to new software rendering capabilities. Siri can also give you more personalized information, including the ability to find event information and reminders in other apps. And Siri can now play audio files from third-party app providers.

       Live text: Live text lets you interact with text in images. For example, if the text is an address, you can tap it to open the address in Maps. Or you can select text from a photo and copy it into a document. Live text is a great addition to iPadOS 15.

       Built-in apps have been updated: iPadOS 15 provides performance enhancements and interface upgrades for all the apps that come preinstalled with it.

      

Don’t need or use all the built-in apps? If so, you can remove them from your Home screen. When you remove a built-in app from your Home screen, you aren't deleting it — you’re hiding it. This is due to security reasons that are beyond the scope of this book. However, the built-in apps take up very little of your iPad’s storage space, and you can easily add them back to your Home screen by searching for them in the App Store and tapping the Get button.

      Finally, the iPad models vary in screen quality and resolution, camera quality, and so on. Logically, the bigger the iPad, the bigger the price and higher the quality.

      Storage is a measure of how much information — for example, movies, photos, and software applications (apps) — you can store on a computing device. Storage can also affect your iPad’s performance when handling such tasks as streaming favorite TV shows from the web or downloading music.

Streaming refers to playing video or music content from the web (or from other devices) rather than playing a file stored on your iPad. You can enjoy a lot of material online without ever downloading its full content to your iPad.

      Your storage options with the various iPad models range from 64 gigabytes (GB) to 2 terabytes (TB), which is equivalent to 2,000GB. You must choose the right amount of storage because you can’t open the unit and add more as you typically can with a desktop computer. However, Apple has thoughtfully provided iCloud, a service you can use to back up content to the Internet. (You can read more about iCloud in Chapter 3.)

      How much storage is enough for your iPad? Here’s a guideline:

       If you regularly work with large media files, such as movies or TV shows, you might need 512GB or higher. For example, if you shoot 4K video at 60 frames per second, that will take roughly 1GB of storage space for every two-and-a-half minutes of footage. In light of this fact, at least 1TB of storage may be more appealing if you shoot a lot of video.

       If you like lots of media, such as movies or TV shows, you may need at least 256GB.

       For most people who manage a reasonable number of photos, download some music, and watch heavy-duty media, such as movies online, 128GB is probably sufficient.

       If you simply want to check email, browse the web, and write short notes to yourself, 64GB likely is plenty.

Do you know how big a gigabyte (GB) is? Consider this: Just about any computer you buy today comes with a minimum of 256GB of storage. Computers have to tackle larger tasks than iPhones, so that number makes sense. The iPad, which uses a technology called flash storage for storing data, is meant (to a great extent) to help you experience online media and email; it doesn’t have to store much because it pulls lots of content from the Internet. In the world of storage, 64GB for any kind of storage is puny if you keep lots of content (such as audio, video, and photos) on the device.
