It used to be that if you wanted to do any video editing aside from trimming, you'd have to pull your video into iMovie or a third-party video editing app. With iOS 13 that is no longer the case - the updated operating system makes just about all the photo editing tools available for videos as well. Now you can adjust the contrast, brightness, saturation and more, add filters, crop, rotate, straighten and mute audio all from the Photos app.
Apple has updated iPhone's photo editing interface in iOS 13, making it more intuitive and adding a few new features and tools as well. You can now fine tune filter intensity, flip photos, and adjust their perspective along the x and y axes. Flipping a photo simply gives you a mirror image while adjusting the perspective along the horizontal and vertical planes basically lets you adjust the viewing angle, similar to Instagram's perspective correction tools. Here's how to do both on iPhone:
iPhone's screenshot feature received an update with iOS 13 - the ability to capture an entire Safari webpage in one shot. A full page or "scrolling" screenshot is saved as a PDF though, so it isn't technically a new ability, as you could do this prior to iOS 13 with the "Save as PDF" Share menu option. This makes it more convenient though, and gives you instant access to the screenshot's markup tools so you can quickly highlight, circle or cross out text, add notes and more.
Here's how to take a full page screenshot on iPhone and iPad:
With iOS 11, Apple adopted the High Efficiency Image Format (HEIF) as a replacement for JPEG on both iOS and macOS. The HEIF format saves a considerable amount of storage space with its .HEIC files (High Efficiency Image Container) being up to 50 percent smaller than the same image saved in JPEG format. Despite the smaller size, the HEIF format can capture 16 bit color whereas the JPEG only handles 8 bit. Clearly HEIF is preferable to JPEG right?
In the recently released macOS Mojave, Apple has added another feature to its Continuity suite called Continuity Camera. The feature lets you take a photo or scan a document with your iPhone's camera and have it instantly available on your Mac. Continuity Camera works with several native apps including Pages, TextEdit, Keynote and Notes, and basically bypasses several steps that you would normally take to get a photo from your iPhone into a document on your Mac.
