    I've been reading about the GoPro the Flip and other low cost underwater video options. There is a lot going for the GoPro, but one big negative in the blur factor. It's early days but it looks like eyeofmine may have an after market fix:

    (It's on Youtube, but I can't post it here due to my low post count. Just search for "GoPro Hero Underwater Focus FIXED")

    I just watched that and I think you are confused. The camera he is showing is not the Flip camcorder.

    Wow, those are some great results! I love how they have direct side-by-side comparisons. My uneducated guess is that you simply need an airtight flat port in front of the curved housing--either as an add-on or with a new housing. That would allow the view to focus, though with a slight diminishing of the field of view (as you can see in the comparison shots).

    I bought the gopro hero hd and i emailed them after discovering the focus problem underwater. This was their response:
    Due to the curved lens of the waterproof housing for the HD HERO camera and standard def Wide HERO cameras, you do get a slight loss of sharpness/focus to underwater images. In video mode with the standard def camera this hasn't been very noticeable due to the lower resolution. With the HD HERO camera this becomes more evident at the higher resolution. Our developers are looking into whether we can possibly offer a different housing or housing lens in the future to correct this issue.

    I should add that besides this, the camera is incredibly cool. Tiny, can shoot for long periods of time with 8 GB SD card, and above water you can do things with it that you just can't do with any other hd camera out there. So with any kind of fix to the blur issue, everyone is going to want one. The only other issue is the files are HD Mp4s that can choke up the average computer so I have been encoding the files all to friendlier hd formats such as DVCPRo HD (i'm a mac guy without one of the new intels) which is a format that looks awesome but can still play on an older laptop.

    eyeofmine.com came out with a housing to correct the underwater blurring issue. It was just as Gombessa said, "an airtight flat port in front of the curved housing". I ordered one for a trip to Maui in June.

    Hi,

    there is another solution from germany goprofocus.com

    It is actually a replacement lens and so it is a cheaper solution and it looks much better than the eyeofmine version.

    This looks like a flat port diopter (close up lense). I would like to see them use the dome port instead because with a flat port, you will lose 25% of your picture angle, which is a lot in U/W videos/photos. One would have to pull the camera away from the subject in order to get the image in the frame. The greater the distance the worst the picture because you are shooting through more backscatter. Is there any room to put the diopter on the inside of the dome port of the GoPro?

    Hi,

    it is actually a Flat Port without any diopter. So it does not change the pictures size. It only reffers to the optical light breaking point from water to air. So optically it will do the same picture distortion as the dome lens, but with a sharp image. All underwater images will be distroted in that way. This is related to the physics of water.

    If you would put the flat lens into the dome lens the focus will drop again. The main issue on the blurred image in the hero hd is the fact that the light coming from the water is hitting the dome port first.

    underwaterhero,
    I am interested in the lens with the color correcting filter for blue and green water. Do you have a Idea of when these may be done?
    Thanks!

    Hi
    Thanks, no diopter, but the picture size will increase when you change from a Dome to a Flat port. The subject will look 25% closer through a flat port than through a dome port at the same distance. I just bought the GoPro housing the dome port is too small in size for that wide angle lens. The eye of mine is the same flat port. I may just buy the Gopro camera and place it in an old Ikelite SLR housing with a 6 inch dome port.

    I am really liking all this video correction on the Go Pro. I love my camera, use it from scuba diving to driving shot in my car, to everything in between. Just wish the underwater shots were a bit more crisp, otherwise I love this camera!

    underwaterhero,
    Is there only one filter? If so is it for blue or green water? And can I ask what it is made of?
    Thanks Again.

    @TSwain,

    there is only one filter. It is a light orange which did turn out to work good for both. I did some testing with different colours for my DSLR Camera and I used this colour in all different types of water already. It is actually a filter gel which is also used for stage lighting. I do have a contact to one of the manufactures and they do this very special mix for me.

    regards

    Hey guys
    Ive made another kind of fix for the GoPRO
    Check it out HERE
    Inexpensive and it works really well, without changing the housing in anyway

    Hi all,

    I recently got a GoPro Hero HD and just got the flat lens fix from GoProFocus.com and already have it installed. I'm itching to get out in the water here later this afternoon to see how well it works. I won't quite be going deep enough to warrant using the color correction filter just yet, but I'll let you know how it works when I do.

    One thing I did spot right off was that the lens had a small scratch upon arrival. Not sure if it will be noticible in the final product yet or not, but as a photographer by day, it cought my attention right away.

    Jon
