How to deselect certain services/widgets on individual pages?

Aloha! Bold Photography Pro theme on www.willigphotography.com I am trying to figure out how to switch of the visibility of certain services/widgets. For example: On http://willigphotography.com/map-project-wedding-2/ it is also displaying the "About Me" text as well as the Instagram feed and the "Publications" section (which is the renamed Services-function...). How can I switch those ones off on that particular site or on blog posts? I guess once I understand that particular function, I will be able to rework some other similar issues I am still having with my new site. Thanks upfront! Thomas
