Good evening Brian and welcome to the Events Calendar Support forum!
Thank you for reaching out to us.
I would love to help you with this topic.
To answer your question, yes, there are other approaches to achieve what you are looking for.
Just to set expectations, as you might know, the scope of our support is mostly to get our wonderful customers started on the right track to customize their site and to help them in case of issues. We unfortunately do not provide complete support for customization.
With that in mind, a simple way to do that would be to create a customization for your photo view. You might want to read our Themer’s guide to see how that works. If you include the code directly in the customized page template, it should not impact the widgets.
The other way to do this would be to add some conditionals (IF) to make your filter specific to the content area and not apply to the widgets
Let me know if that helps get you started.
Have a great day!
Geoff B.
