Hugyfot Housing for Nikon D90 4 User manualFirst dive is a checkdive without the camera in the housing.Check all buttons under water.1. PrefaceA camera in an underwater housing offers a lot of advantages to the profes-sional and amateur underwater photographer: impeccable exposure due to the use of the most modern exposuretechniques of the camera; direct view on the subject, very short reaction time and swift imageprocessing; exact and swift focusing due to the autofocus objective; parallax faults no longer exist because one looks through the objective(all settings are displayed on the LCD-screen);as the camera can alsobe used on land, a second camera is not needed.As housings and flashes have a long lifetime and are quite expensive, sometime should be invested in looking around to find the right equipment. Do-ing this in cooperation with a professional salesman is probably the bestsolution.Different criteria determine the final choice of the camera: recording technique (viewfinder, controls, …); functionality and comfort (design of the housing, control switches andtheir ergonomical position, …); price.Also: some elements that determine ones choice when buying a safaricamera are not important at all when purchasing a camera for “underwater”use. Cameras are always designed for “on land” use. Therefore HUGYFOTalways designs its housings from the divers’ ergonomical point of view andtranslates this through the controls.
