PT-10 with DS-50 - silly diffuser question

I recently splashed out on an Olympus C4000 and PT-10 housing, and a Ikelite DS-50 with a TTL slave, in preparation for a diving holiday that we're about to go on. I've never used much more than a hired MX-10 in the past, so this is probably a very silly question! But since the manual was in Japanese, and I only got a couple of sheets of English instructions from the distributor, I feel I ought to ask! (The sheets cover the basics, but mainly concentrate on preventing the housing from flooding.)

I've plugged the kit together, and tried it out above water, and it all seems fairly straightforward. Is there anything special you need to do with the camera or housing in this setup?

In particular, I was wondering about the diffuser on the front of the PT-10.

Do I need to cover it in some way, to direct the light towards the TTL slave, in order to prevent backscatter from the internal flash? Or is the light from the internal flash so insignificant compared to the DS-50 that it's really not a problem?

Are there any other tips to recommend to an absolute beginner regarding this particular kit ? (I'm doing all the background reading I can at the moment, hoping to bring back some nice photos!)

Thanks in advance for any advice.

Cheers,

Glyn

Who did you purchase it from?

Take a look at the instructions on my web pages:

Olympus Housing Instructions

Let me know if you have any specific questions.

Cheers,

Thanks for your help. I bought the kit from www.camerasunderwater.co.uk.

There is a fair overlap with your instructions and the ones that camerasunderwater.co.uk supplied. However, the instructions on your page included a few points that I don't remember reading in the printed English sheets that came with it, so that's very helpful.

Thanks a lot.

I am supposed to meet the people from Cameras Underwater UK at DEMA next week. They seem like nice folks.

Also, I am working on a better revision of the instructions. Any suggestions would be appreciated.

Side note-do you think it would work if I made it postcardware (where people who use my instructions send me a postcard for it)?

Why not make it "digital photoware". You could then have a webpage with great shots from the stuff you sell.
