    Canon S90 Underwater

    Amigos,

    Early this month I dedicated myself to shooting nothing but my new Canon S90 underwater and above in Cozumel.

    Learned a lot and this little camera has pretty damn impressive capabilities.

    Samples attached, lots more if interested email me.

    Very nice! May I ask what you used for lighting?

    Folks,

    Lighting was two Ikelite AF35 strobes. Ikelite housing which has the cool Canon S90 front control ring usable.

    Nemrod, yes any wide angle venue was shot with an Ikelite W20 wide angle zoomed "one tap" to probably 35mm equivalent to eliminate the slight vignetting without zooming. Still plenty wide

    Hope you enjoyed them!

    CompuDude,

    Yes, two strobes can make a WORLD of difference. I notice Ryan in FLA and you communicate and he can set you up to improve your results.

    Harry,

    Glad we got to meet and yak about UW photography.

    Shoot me a PM from my card when you get a minute if I can help you

    Later!

    Very nice pictures--thanks. Were you using the Ike strobes on sTTL in the aperture or shutter priority, or setting them manually? I'm taking the same rig (with a different strobe) to Cozumel in 2 weeks.

    Mel,

    I shoot all Canon cameras using TTL which puts out "pre-flashes" usually in milliseconds to help a camera focus and determine exposure. Modes usable on the Canon S90, G10, G11 (which can be hard wired to an Ikelite Digital Substrobe) are P, Tv and Av.

    The Canon S90 without a hots shoe does practically the same when paired with the AUTO sensor of Ikelite's AF35 strobe. It will read the "Start" and Stop" (or quench) of the S90's flash output and mimc it to get as close to a proper exposure.

    For the UW shots posted I used Av mode where I adjusted aperture. I DID go in and dial in like - 1 2/3 EV to the OVERALL exposure which makes for a bit bluer richer background water color before switching the Canon S90's Control RIng function to Aperture.

    One thing I 've made notes for my next Canon S90 UW shoot is try Tv mode and boost the shutter speed to maybe 1/125. When shooting in Av mode the shutter speed was "locked" at the bottom of the automatic flash selection, 1/60th. Sometimes despite the flash freezing a critter's motion the background was blurred a bit.

    I of course tell people this was my "artsy" interpretation LOL......

    The Ikelite AF35 Sensor has a dial from 1-10. 10 is highest TTL flash output and 1 the lowest. I set the strobe rear control KNOB on "AUTO" and then fine tune TTL flash with the side flash output knob plus aperture.

    I always set a fixed ISO, most of these likely ISO 80 -100 since it was bright light conditions.....

    Overall the little Canon S90 was a blast to shoot with above and below. I'm sure I could have done the same with a Canon G11 and may still add one of those to my arsenal

    Good luck shooting on your trip!

    Great pix!
    I'm currently using, and liking, my G9 setup (Ike housing, Ike strobes and TTL and INON wet lenses).
    It sounds like I would need to give up TTL if I went to the S90 and wanted to use my DS125 & DS51. I find TTL liberating as it allows me to concentrate on composition and lighting, rather than exposure.

    I usually shoot in TV mode at ISO 80 and get exposures around 1/250 and somewhere between F2.8 and 4. Unless I'm shooting an open reef scene, the strobes don't fire fully.
    eg: Venture Explorers Live-Aboard in Turks & Caicos

    A few questions
    Did any of your pix use a wide open aperture?
    With decent strobes is a fast lens much of an advantage?
    At ISO80, is there much of a difference? The G9 is definitely week at high ISO speeds.

    Thanks
