Hi All!

Finally, I was able to test underwater housing we wre talking about a while ago. Here are some pics - http://hlop.net/gallery/Fairlight

I should tell you - I'm not experienced snorkeler and not experienced underwater photographer, so, please, don't kick me hard :)

Hlop - do u have any actual photos of the cam in it's housing? I would be very interested in seeing them!

Hlop,

What brand of housing did you use for the D70. Were you using the kit lens and if so did you need to use a close up lens to stop the underwater refraction between the port lens and the camera lens.

Cheers,

Darryl.

These look like it would have been terrific fun down there... Haven't gone through all pics in your gallery yet, but I'd like to see a pic of the cam in its body, not sure how the lens (which ever is used) is intergrated into the "front" of the housing...

Cheers,
Mudder

Don't have a good picture of camera in the housing but it looks like this:

As you can see, there is plenty of room for the SB800 but this time I used built-in flash

I used kit lens and no closeup. Actually I've got set of closeups but I didn't think about using them in this way. It might be an interesting idea and worth to try

Hlop - a nice collection of pics for your first attempt. I feel that the built-in flash is not strong enough and the SB800 would be better.

Just a suggestion but would try playing with WB (if you shot RAW) to get less of a green caste. Before anyone shoots me down by saying that it was green I would add that by removing the green the colours would strike out more IMO

Cheers

Chris

Hlop,

Tou are a more risky man than me to put your D70 into an underwater bag. The problem you face when using such a bag for anything more than a depth of 5 meters, is the pressure put on the controls.

I once had a bag as such, for a P&S and found that after a depth of 5 meters the controls could not be used. I found that you were only able to take 1 picture as the shutter button would not return because of the pressure on it, however a friend of mine had overcome this by the attachment of a tennis ball and would let the camera surface then pull it back down for another pic.

To much mucking around for me. With most housings you can dive to a depth of 60 meters, I have had mine to 68 meters with no problems.

Cheers,

Darryl.

That's what manufacturer says about the housing:

With this housing, a whole new world of applications opens up for your standard SLR camera: Inside the housing you can now take the camera safely canoeing, snorkeling or even diving, up to a depth of 20 m / 60 ft.

As you descend, the air is pressed into the camera. Due to this, the pressure inside the housing will remain the same as the surrounding water pressure. (this is the reason why ewa-marine housings are so safe to use: implosions are impossible) Due to this, we have to start the dive with a suitable amount of air inside the housing. The foam pads supplied with the housing are part of this air "reservoir" and additional air should also be blown into the housing, via the valve at the rear, to ensure that the maximum potential volume is being utilised.


So, accordingly to above sentences there is no pressure problem. At least shouldn't be and I didn't experience sympthoms you described

You're right thare are better and more reliable housings but, firstly, I'm not going too deep - 10 meters is my limit, secondly, 390 aussiebucks vs. 1200 US bucks makes the difference for me - I'm a casual snorkeler and I'm not a diver at all. When I'll decide to dive I'll buy proper housing

 BTW, could anyone suggest any other interesting places for snorkeling around Sydney and NSW?

bass and flinders point at cronulla is a great place with plenty of colourful fish as well. you may need a filter for different water colours. either a pink filter for green water and an orange for bluewater should take some of the milkiness away.

Thanks jethro.
Do you have any examples of photos with these filters?
