Puget Sound is salt water, but thanks for the comments! And you've got some great shots in your gallery - keep up the good work!!!


Thanks! Well, more my English than anything else, I tend to refer to cold water as being "fresh", forgetting about the proper meaning of fresh water... :)

Very nice review of your G9 baptism in fresh water! I learned to dive in Switzerland and had some nice dives in Barkley Sounds on Vancouver Island two years ago - I know what you're talking about in terms of cold water ;-) In fact I wish I had started earlier with underwater photography, would be nice to have some pictures from the Swiss lakes at hand...
I am using a G9 for a few months now with the Ikelite housing and a Inon Z240 strobe (no wet lenses (yet)). My first setup with strobe. I can confirm almost everything Bruce mentioned about the camera. A few points:

- manual is the way to go. Initially I used the Av setting (aperture priority) with the strobe in S-TTL mode. This produced some nice pictures with good exposure, but, as mentioned before, the camera almost always chooses 1/60s shutter speed. In order to be able to play with the background colour and to have some more margin for a steady picture I prefer to use 1/125 - 1/250s for macros in manual mode.

- The G9 is NOT suitable for any sort of TTL if set to manual mode as the power of the internal flash needs to be adjusted manually too in this setting. Not a problem though, rather room for creativity.

- WB: I use the automatic whitebalance setting when shooting with the strobe. I am happy with the results, software treatment of the WB is rarely necessary.

Some sample pictures are probably more interesting than my text... I recently created a little picture gallery of my first tries with my setup (which is described in more detail here).

Thanks for the hint, I have posted on the seaslug forum. Bill Rudman has given his valuable opinion on this matter. It looks like the white bit I was wondering about belongs to the anterior foot of the nudibranch.
