I am trying to get the best overall setting to use while diving in 30ft - 60ft of water with very good visibility with a Nikon 4300, Fantasea CP - 4 pro housing and Nano slave flash. The 4300 does not have a UW scene mode. I have only been diving for a year. Last year I did not have the slave flash and the pictures were ok. I thought I would try the slave this year but want to be able to still point and click. I still need to be thinking about the technical aspects of the dive.

Any sugestions would be appreciated

Thanks
