Problem with image scaling during parallax scrolling

Hi, I have a problem with an ugly scaling photo in the hero section. I wanted to get a parallax scrolling effect. It worked, but at lower resolutions (still on desktop) the photo goes down revealing the background of the section, for example, already at 1600px.
Does anyone have an idea how to do it right? So that the photo zooms out?
The second thing - how to solve parallax scrolling on tablets and mobile? Do away with this effect on other devices?
