1. A button for use with an image capture device in an underwater environment, the button comprising:
a movable plunger configured to cause actuation of the image capture device; and
upper and lower components collectively defining an internal cavity configured to receive the movable plunger, the upper and lower components configured such that actuation of the image capture device is prevented until a threshold pressure is applied to the upper component that is greater than external water pressure applied in the underwater environment, the upper component including at least one opening configured to allow water to enter the internal cavity to modify an internal pressure within the internal cavity so as to reduce the threshold pressure required to actuate the image capture device in the underwater environment.
