After a few days involutary free (= unemployed) , I finally finished my HD (1920*1080 full HD) underwater video camera housing mounting frame for my
Bottom Cam Mark III. 
Ready to be tested in Maarseveen and Hemmoor (depth rating ~100m)
Now fitted with 3 standard halogen lights (for the fotos and testing) but will probably be fitted with 2 monster hartenberger lights (like on my previous mark I and II versions).
Check here for the older versions now retired :

http://www.apnea-amsterdam.com/forum/index.php/topic,293.0.htmlAnother big improvement (besides being HD now) is that the camera has a 500GB harddrive so can run for days on end without tape changes. Old DV tape based cam was max 1 hour video, which for a normal dive session is a bit tight. So now the battery life is the limiting factor, but seems to do about 3 hours continuous on current hi capacity battery and battery is fast changeable between dive sessions if needed (not under water obviously, which would be a cool feature).
