What dates do date range pickers default to?

I'm working on a photos app that lets you filter photos based on date range. When a user selects the "Date" filter, two calendars appear and from there they are able to pick a (to and from) date range.

What dates do date pickers normally default to?

I'm thinking the From should default to "the earliest possible date" (ie - when the user signed up essentially), and To defaults to the current date.

Is there a standard for this?
