What Do You Carry: Photographer and Tech Journalist David Cardinal

David’s gear changes with each project, but he never leaves home without his Scottevest photo vest or his Samsung Galaxy S II, probably the "single most important piece of tech" he carries.

This professional photographer doesn't go anywhere without his souped-up laptop.

Not all flights can accommodate the use of Cardinal's XPS 15, so he turns to his tablet.

This USB thumb drive provides David with a secure connection and access to e-mail, and it stores his documents.

This is one of three D-SLRs that usually make the trip.

The D7000 is a backup for when a smaller sensor makes more sense.

David uses these earbuds when he's listening to Audible books.

This headset is used to make phone calls.

David planned this shot, using The Photographer’s Ephemeris, so that he knew which temple to climb and where to be situated as he waited for the sun to rise.
