If I could narrow the view down 50% then I would choose the bottom picture (kite mount). To see the wave height even clearer simply fly the kite lower. No nauseating shaking, no lines in the middle of the view. But yeah, the line mount picture is an awesome place if we could just solve the shaking problem completely.
Are there cameras like the GoPro but with much narrower field of view? What was the camera and field of view you used for the bottom picture?
here's the deal, when I originally set out to design a kite line mount, I was merely looking at being able to take stills using one of the early generation gopros. these were not HD capable at the time so I never focused on anything but doing stills. once the HD was released I started using the same mount for videos. I knew the video footage quality would suffer but the mount still worked.
I eventually redesigned the mount to be efficient for doing video. this is the new line mount that is available on preorder through camrig.com
so there are a number of things that help it film video more stable.
the weight of the gopro camera plus housing has been exactly balanced so there is no need for any additional counterweights.
the line manager arms have been widened so this allows the camera to sit up slightly higher on the lines and this helps with minimal wobbling caused by having the mounting arms so narrow.
one last design criteria was the camera needed to be positioned in the correct orientation for video filming. all of these issues have been addressed with the new line mount.
and yes it does work for photos as well.
keep in mind that the gopro silver edition camera has 3 different field of view video settings. you can choose between narrow, medium, and wide. while in photo mode, there are 2 different settings available with wide and medium.
here is a quick edit that demonstrates the difference with the 3 FOV options. my apologies for the footage, I did not double check the camera position before going out so it shows the rider non centered with the frame. but it gives you a clear idea of the differences between the FOV.
