I want to reduce spacing between Heading 3 and Paragraph 2 on One Page

Site URL: https://www.rentphotoville.com/photography

How can I redice the large spacing between Image, Heading 3 and Paragraph 2 on this page? This site is on v7.1.

I changed the space to my liking on this page, but it totally screwed up the rest of my pages.

Thank You

Jim
