Over the years Cally and I went onto various Scuba Diving Trips on which we literally took thousands of underwater pictures.

An additional Hartenberger flashlight was bought later for additional illumination (and to get some light into the darkness of our night dives :-) Here's a selection of our best underwater pictures :
