Thanks Sandy, the admiration is mutual. Youve got an excellent eye for composition, a great sense of timing, and an appreciation of fine photography
The key issue in getting a strobe for the S40 is the fact that our camera uses a preflash. This is a brief flash that always fires a millisecond before the main flash and is used to set white balance and exposure. The preflash will fool all older strobes. This limits us to the new digital Strobes such as the DS-125 from Ikelite or the YS-90DX from Sea & Sea. I bought both from B&H tried them both out, and decided in favor of the Sea& Sea. It was much lighter and synchronized better with our camera. You have to set the strobe power manually. I found this wasnt a problem, and I missed few photos this way. There is a dial with 12 different levels.
As fas as attaching the strobe to the camera, you can buy a complete package with strobe, baseplate, strobe arm, fiberoptic cable, and hardware. Go to B&H and search for SEDLK.( I think thats it their website is down). There is a black velcro tape which you will need to cut to match the WPDC300 housing. It blocks out the internal flash, and attaches the fiberoptic cable to the housing. Dont worry, they give you an extra piece of velcro tape! I attached a small divelight to my setup with a rubberband for night photography, it also doubled as a focus assist in low light.
As far as settings, I used either aperture priority (Av) or shutter (Tv) priority. Set the internal flash to always on, no red eye reduction. Set the internal flash power at minus 2 to save battery juice. The white balance can be set to cloudy (or custom, and meter off a grey or white object). If you use shutter priority at a speed faster than 1/250, the photo is taken at 1/250 but the f stop is increased. This way you can get the full range of f stops in shutter priority. I took most of my photos in macro mode, and also did touch-up in photoshop.
Email me if you have any other questions. I see you do event planning. If you do medical meetings in the Caribbean let me Know! Thats how I dove in St Thomas, I played hooky for a few days at a medical meeting. (Golf is too boring.)
