    Hey, great video! One day I hope to be able to dive there, but in terms of $/dive it's sooooo expensive....

    Interesting comments about 25fps vs 50fps. I've been using the latter so that I can have the option of slo mo in post, but I'm also coming round to the idea that I may as well just shoot in 25p. I've hacked my GH2 so the bitrate is 50 Mbps for both formats anyway.


    Cheers,
    Matt

    The slo-mo is something I use often. If I need to stretch a clip to fit in a time frame or slow down macro, the 60fps is indispensable.

    Thanks matt. It depends on what is the final output format. If it is 25p it's better to use 1/50 shutter speed in any case. For the recording format this was not a macro trip so no slow motion needed

    Hammerheads seem to be somewhat common here in West Palm Beach and Jupiter. We have a few Dive Ops that specialize in shark dives. I just can't convince my wife to do one with me.:idk:

    You should go and do the dive really. I have now done some analysis on the footage and based on that I would say that my set up was ideal in terms of settings and equipment. Even if I did not have the filter it would have made a very marginal difference in terms of image quality with the shutter at 1/50

    BTW, which filter did you use?

    This one Deeproof Red Color Correction Filter for INON UWL-H100 Lens

    Is the only I could find that pushes on the UWL-H100. I have compared it to the UR/PRO and it is very similar but not identical I think something like 2700K M5 in a sunny day

    I saw those when looking for the Aditech/Mangrove filter I selected. It's looks very similar to that manufacturer's line of filters. Did using that pop-on filter cause any reflection issues? I've heard the pop-on ones are more prone to that. I might have tried one of those if I could have found one that fit the odd size of the Wetmate.

    Not with the inon lenses that have 5 elements all coated with anti reflective plus I also have a hood on the lens

    So did you find mounting the UWL-H100 more compatible with the Rx100II Nauticam housing and easier to mount? I think I remember from your blog that you had some issues with that lens and the LX7 housing.

    On the subject of shutter speed, I wonder if slowing down my shutter would be beneficial on a darker dive like the Spiegel Grove. Would it be necessary to reduce the frame-rate with the reduced shutter speed and/or would the bit-rate loss be too much of a trade off?
