Hi MsMaude,
It sounds like you have questions related to customizing your Lock Screen in iOS 16. The support article Create a custom iPhone Lock Screen outlines that process and options in greater detail. Specifically related to the clock and image are the following:
"Change the clock style on the Lock Screen
You can change the font and color of the date and time on your Lock Screen.
- Touch and hold the Lock Screen until the Customize button appears at the bottom of the screen.
- Swipe to go to the Lock Screen you want to change, tap Customize, then tap the Lock Screen image.
- Tap the time, then choose a font and color.
To reset the date and time, see Change the date and time on iPhone."
and
"Customize your Lock Screen photo
If you choose a photo for your Lock Screen, you can reposition the photo, change the photo style, and more.
- Reposition your photo: To reposition your selected image, pinch open to zoom in on it, drag the image with two fingers to move it, then pinch closed to zoom out.
- Change the photo style: Swipe left or right to try different photo styles with complementary color filters and fonts.
- Create a multilayered effect: If you have a photo that supports layering—like an image with people, pets, or the sky—tap
at the bottom right, then choose Depth Effect. - Note: The multilayered effect is available on supported models. Layering may not be available if the subject is too high, too low, or obscures too much of the clock.
- Set the shuffle frequency: If you choose Photo Shuffle, you can preview the photos by tapping
, and set the shuffle frequency by tapping
, then selecting an option below Shuffle Frequency."
Regards.
