Hey! I recently bought the iPhone 15pro and when I use the „focus“ in the camera App by tapping with my finger on the screen a „f“ appears in the corner. I can activate it, but I can’t find out what for. It looks like the sign for „camera aperture“ (I don’t know if this is the right word, it’s „Blende“ in German). What does it do? I didn’t find anything on the apple help pages.

The “f” in f-stop means finestra, Italian for window. The larger the f-stop opening (1.4, 2.8) the less depth of field. The higher the f-stop (16,22) the more depth of field. F8 is probably your sharpest focus
Aperture
F is for focal length. F/stop= focal length / diameter of aperture. Example f stop is 2.8 so 2.8 =50mm/ diameter. 2.8/50= .056, 2.8 at 100mm is 2.8/100 = .028

F
it will solve algebra equations such as f(x)=3(0.54)^x

It’s the Fanta button
On the 15 series, you can capture photos with depth data in non-portrait mode. The icon turns yellow to indicate depth capture during regular photos when either a person, dog, or cat is detected, or when you tap to focus on a subject, prompting the camera to use portrait mode for depth.
