using a 4x5 underwater?

[srmcnamara]

Hey guys,

So I'm looking to do a project on streams, running water, and all that jazz and I've come to the conclusion that I need to get the camera underwater to do this project properly.

The streams and junk are shallow and I'm not looking for total submersion here, just getting the lens underwater. I've also given up on focussing and composing really accurately, I'm going to try the string trick.

So I"m looking for any ideas anyone has on constructing some sort of semi-enclosed thingamabob that will protect my camera (<a href="http://www.thalmann.com/largeformat/anba.htm" target="new">anba ikeda</a>) from, you know, getting wet while the lens is halfway underwater.

My thoughts were some sort of plexiglass box with some sort of filter in the front panel but I'm not sure how I would seal that. The top would probably be open so I could hit the shutter and stuff.



Also, if this is a stupid idea, let me know before I get too far.

I've seen it done somewhere - over on Filmwasters.com I think. Yes, here. But, due to an upgrade the photo has gone although the text and the poster remains

Heavier but same idea is a small aquarium or archival print washer.

can you not apply an aquatic periscope?

They already make a device to do just what you want, it is waterproof and they call it a "fish tank" you can get one at a pet store, or a tag sale, add bricks and/or sand to the bottom to get it to the depth you want and your all set. Before consumer waterproof cameras and reasonably priced waterproof enclosures came along this was the recommended way for amateurs to shoot underwater motion pictures. It was really popular when camcorders that could shoot in lower light came out.

If you add a little D76 to the sand, you might re-invent the Polaroid.
