Not many places to mount camera on eye opening of full face helmet that would not distort horizontal field of view. I imagine camera mounted above nose bridge on helmet opening
You have to make assumptions/conversions based upon film dimensions and camera lens, ie 35mm normal eye view is 50-55mm focal length. 35mm provide slightly larger field of view. Considering there was no apparent distortion in the cockpit with the driver's hands and the front wheels, one must concede would they used a near "normal" lense from the human perspective and appropriate depth of field. Look closer and the lenses actually has moderate characteristics of a fisheye, apprimately 8-15mm focal length in 35mm format.
I believe this is considered the most realistic video out there for an F1 type car. The guy recording this actually had one of this eyes covered (can't remember which website I saw that said that) and was only driving with the other one.
The reason who only see the rear wheel I'm guessing is because the camera is farther forward than the driver and then messes up the angle of view. If you imagine the camera being farther back, you would see the area behind the car better.
Also, the other video that was posted above (http://www.youtube.com/watch?v=k6hGGlmie6U) seems to be to the left side of the helmet as can be seen from the straightaways. Also, the POV is all wrong for that video considering you can't even see the mirrors.
Good point above that the only real way to get the right POV for a car in LFS is probably to be using more than one monitor...
For most of us setting the FOV is a compromise between realistic perspectives and practicality. More monitor real estate allows for more immersive perspectives while maintaining the same level of practicality. Most people would be able to pick up a used second monitor for dirt cheap. It can even have different vertical and horizontal resolutions to the primary monitor and with a bit of setting up displays perfectly.
I'm slowly working my way down from 90. Currently at 68, and I just change it by one degree once a week or so. Usually when I change combo, so I don't notice the difference so much. The only drawback is that I can't see my mirrors any more, and moving 'my' head that much makes me a danger to other drivers. I'm using Aonio's radar panel to overcome that, plus I have other car's engine noise turned right up which really helps.
Definitely worth doing for the feel alone, IMHO, it just feels so much more immersive, but, it'll also give you quicker reactions - the screen's movement is amplified and picked up quicker. As we've not got g-forces to help us feel what's going on, the visual clues are even more important.
that might be true, however, changing FOV in LFS to 33° means "zooming" in - changing focal length itself...i think it should just "crop" your field of view to match the area that your screen in front of you covers...like when you sit in a bus and youre looking through windshield, you see just a fraction because you sit in the back, your view is just "cropped" by the windshield area, not "zoomed in"
Sitting in the back of the bus is moving the seating position back, just really far back. The 'zoom' effect is not really zoom as it is perspective correction.
