With the launch of the 2019 iPhone, Apple introduced some impressive new camera capabilities specifically for flagship smartphones, such as Night Mode (night mode), QuickTake Video and the new ultra-wide lens.
As a result, Apple updated the Camera app design on the iPhone 11 series, which means that some of the existing photo and video functions have been adapted to accommodate new features.
Image filters are a special case to consider. On iPhone XR, XS, XS Max and previous iPhone models, the filter options are accessed by clicking the Filters button at the top of the viewfinder. Here's how to access them on iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max.
1. Launch the Camera app on iPhone.
2. Click chevron at the top of the viewfinder to display an additional setting range above the shutter button. Or, swipe up on the viewfinder with your finger.
3. Click the Filters button (looks like three overlapping circles) on the right side of the settings strip.
4. Swipe to view the 9 available filters and select an appropriate option. You will get an instant preview of the selected filter effect in the viewfinder.
5. Click the shutter button to take a photo with the selected filter applied.
Note that in the final image, you can see the filter icon in the upper right corner of the screen. This appears only to remind you that the selected filter is still active and ready to apply to the next photo. You can turn off the filter by selecting the first Original option in the filter menu.
In addition to the filters, the camera settings range includes options for accessing Night Mode, (night mode), Live Photos, frame rate and timer.
Hope you are succesful.
