header only on front page

Hi,

I’m a new WP user, so I need a little guidance and information of possiblities.

I have the Amplify theme – which suits my needs, however is it possible to have different header on pages?
I mean the front page is great. But on the other pages I would like to change the image and/or make it smaller (default height is 650px, which is quite ok for front page).

Is it possible to make such a modification in this theme and if yes – how can I achieve it?

Thank you in advance for answers.
