I have bought an Olympus u400 and housing as my first attempt at underwater photography. Each time I have used the camera I have noticed an what I would consider an excessive amount of condensation inside the housing. Soetimes its so bad that I can't see the LCD through the back window. Each time I've used the camera it's been in cold water (Scotland / North Sea)

Is this normal?
Can it be stopped / reduced?

Also how well does a strobe reduce / stop backsplatter?

No this is not normal....you may have got some moisture in the housing from a previous leak but its strange that it should condense when you go from warm to cold. Try leaving the housing open in a warm dry area - airing cupbourd or put some silica gel pouches inside to adsorb moisture

Slim,
Go to the local pharmacy and ask them for some of those silica gel packs that are used to absorb moisture. Your problem stems from ambient moisture condensing on the inside of the housing when it gets chilled from the cold water. The process is quite natural and does not indicate that you have leftover moisture from a previous leak. It's the same process as having a pair of glasses fog up on a hot humid day when you walk into an air-conditioned room. What you need to do is eliminate the moisture absorbed in the air inside the camera. To do this, simply place three or four of the silica packs around the camera when the camera is mounted in the housing. Close the housing, leaving the silica packs in place, and go diving. After every two of three dives change the silica packs and dry the ones used in your kitchen oven at about 225 degrees F for a couple of hours and then store them in a tightly sealed bottle for use later.
