We recommend the following:
Camera: Sure, an entry-level DSLR would give you tons more control over light, focus, and depth of field, but a point-and-shoot or current smartphone should do you just fine.
Charger & adaptor (if you’re traveling to a foreign country)
Tripod: In addition to making low-light situations clearer, think outside the box and use a tripod or monopod to go where your arms can’t reach.
ND (neutral density) filter: Makes long exposures possible during the day.
Remote Control: For DSLR selfies and perspectives that don’t keep your eye glued to the back of the camera.
Duct tape: So many uses. So many.
Multiple hard drives: you’ll only skip this step one time.
