iPhone Camera iOS 14.6 XS

I can't locate the exposure compensation (+-) on my iPhone iOS14.6 XS. How do I find the exposure compensation tool? How can I access the exposure tool.

I open the camera, and tap on the arrow (^) at the top center of the camera. When I tap on it the following options appear: Flash, Live button, the ration (4:3), the timer and filters. I find the (+-) tool on other iPhone 14.6, but not on mine.

Thank you,

Linda Dooley
