What some people do is fire their strobes using a slave trigger. It's a fiber optic cable that you mount in front of your camera's flash that fires the external strobe when it sees the flash from your camera.

To reduce backscatter - the reason you'd buy an external strobe - you then do some sort of blacking out of the camera's flash.

Inon sells a film kit for this purpose that attaches to your camera's flash and blocks all visible light but lets the infrared through to fire the strobe. A photo pro at our LDS told my buddy to just use electrical tape and leave a small hole in front of the fiber optic cable end.

My dive buddy has an A620 in the Canon WP? housing. He just shot it last month with the Sealife SL960D strobe and had better results than using his on-camera flash. The D model the ability to deal with the pre-flash on most popular point/shoot cameras also. Although as I recall, we were able to turn it off on his camera. PM if you'd like to see an example of what you can expect from this setup.

I have another buddy who shoots Inon strobes with a Canon G6 in an Ikelite housing. He uses the Inon film.

You're definitely looking at better strobes than my buddy.

I meant what sort of results you can expect. The flash is this one:

It just screws to the bottom of the housing and I believe he epoxied the fiber optic fitting directly to the front of his housing - it's just a small piece of opaque plastic.

Here's a picture taken with it. All I did was bump both the brightness and contrast up +10 in Photoshop.

Okay, very cool pic no matter what strobe you used.

Anyway, I have the same housing (with an a610 in it), and I bought a cheap SnapSights strobe that is slave linked, but no cable. As stated, the arm just screws on the bottom. All you really need to look for s slave link. The preflash thing is true, most Canons can turn it off, but you still want a strobe that can deal with it. Other than that, the sky's the limit.

diversteve, thanks for that info. I just recently bought a Canon A630 and a Canon housing. I've been using built-in flash. I think I now know what I want on my Christmas list, Sealife SL960D.

Will the pre-flash most digicams have cause the strobe to trigger to early?

Before you go and sit on Santa's lap here is something to consider. The Sea & Sea Y 15 is a far better strobe compaired to Sealife. It slaves to the camera without needing the cable and the recycle time is way faster than the Sealife. Although the tray and arm do not come with it they are extra.

You mat have read about shutter lag being an issue with some P/S cameras well if you have to wait 30-45 sec. for the flash to recycle you will really flip out...
I'm not saying the Sealife is not a good product but when it comes to strobes the Sea & Sea is something worth looking at.
Hope this helps.....

The difference for my buddy was that his was a Christmas present so $250 was the upper limit from his mother-in-law. And LP has it for $249, not sure if ST can match that price.

Recycle time is a factor. We timed the SL960D at around 10-14 secs. recycle time depending on battery condition and power setting.

For $130 more, I'd probably buy the Sea&Sea if I did photography. Actually I'd probably by a better Inon instead. But not for $250...

DevilDiver, good info on the YS 15. The down-side is that I have to buy the arm extra ($150). ST makes it affordable by selling the flash and arm for $380. I just don't know if Santa is that generous. I may have to start saving.

The next question if I should decide to buy this: do you have a spare bedroom or a couch that folds-out because I'll be crashing at your place? Also, if you can recommend a good divorce lawyer, that would be appreciated as well.

Ha.. There is no such thing as a "Good Divorce Lawyer"! No problem... If the sock is on the doorknob you will have to sleep in the car. (Guy rule # 17):smiley20:

I have the same camera. I went for the Ikelite housing and a Ikelite DS125 substrobe. I know a lot of money.... but hey I'm single ;-) Might be worth saving for though. I think this will be more than adequate until I'm ready to upgrade to DSLR and the strobe will work well with a DSLR so I won't be replacing that to. Long term it will be less money.
