Drawing Lines for Video Instruction

[O.B.Left]

I personally do, yes. That said, you of course have to see what the shaft is doing, as well as sweet spot motion/rotation. Very few can have a good hand path without a good shaft/sweetspot plane and get away with it, and basically nobody can get away with it on the downswing.

Ray Floyd comes to mind re: backswing.

All of that said, a good argument can be made that if the camera is correct, all that matters is the sweetspot in an uncompensated motion.

Perhaps Ted and Jeff will chime in as well, as I know they'd both have good insights into their preferences.

Thats pretty cool stuff EdZ. I guess you'd have to take into consideration the number or shifts etc as you monitor the hand path. The backswing may not be the same as the downswing etc. Interesting concept though on pressure points, hand paths etc. Thanks

My questions are from where do you draw these lines? Do you draw them both from the hosel, both from the inside aft quadrant of the ball, or somewhere else? I also know you can draw another line for the elbow plane. Which lines do you all use and how do you draw them? What about the face-on view as well?

Plane Angle Lines should always be drawn from the Sweetspot through the selected Plane Angle reference point, e.g., the Hands, Elbow, Turned Right Shoulder or Squared Shoulder. Avoid drawing lines from the Hosel unless you intend to illustrate a true Clubshaft Plane.

Remember, the Clubshaft always rotates about the Sweetspot and not vice versa (2-F). It will move off its own Plane and onto the Plane of the Sweetspot during the Backstroke and will return to its Plane during the Release Interval. After Impact and the Follow-through (Both Arms Straight position), it will once again seek the Sweetspot Plane during the Finish Swivel (2-G).

Summing up: No matter the originating Angle of Inclination or any subsequent Shifts, the Sweetspot Plane represents the true Plane of the Golf Stroke. It is therefore imperative that any Plane Angle Line drawn intersect that point.

EDZ,

I think you are discussing some VERY important concepts in video teaching. Would it be asking too much for a quick tutorial? I'm hoping you may have saved a couple of pictures of right and wrong in regards to how you are watching the sweetspot plane, as well as how you are watching PP#1. I have a hard time learning without a picture in my mind.

If it would take too much time I understand 100%.

Thanks for considering,
Kevin

One thing I have to work on with my video is to make sure the camera is position the same distance and correct height on easy swing or making comparisons to previous swings is futile.

Same lens or amount of zoom too. The wider the lens the more parallel lines converge or bend even. Im not a photographer but I work with them and think the naked eye is about the same as a 22 or 24 mm lens or something. A fish eye lens makes straight lines look weird. Some one help me out here, TAG!

Yep, when using a wide angle lens the the image bends or 'distorts' more and more as you move toward the perimeter of the frame. The image distortion increases as the lens size decreases.

Here's an example.



More importantly, perspective distortion increases when the camera is not aligned perpendicularly to the subject.

Absolutely imperative! A couple of informative lines are the tush line from DTL and the lead hip line FO (both will reveal a proper or improper pivot).

I noticed your swing thought and wondered if you get that low slope then gradual rise to the top ball flight. The goal of which is a softly landing shot?

I know the swing is linear than angular. It just seems very easy and consistent to thrust down while maintaining the wedges. If I exaggerate the wedges and thrust, will I get that distinctive ball flight? If I hit the sweetspot plane or line, will that give the ball flight its distinctives?

Camera setup is so key, like EdZ stated.

I also think this is a fantastic camera angle to use with golfers.
