To draw the lines correctly the line from inside the heel to the inside of the heel - it must be perfectly horizontal as you can manage when setting up the camera.
I untilted the picture and drew a perfectly horizontal line and then a drew a vertical line directly half way... then I drew a line vertically from the tip of the false tripod and then drew a line between the two reference points which show the amount of tilt (as they were horizontal before the picture was untilted). Yes, that few degrees out and you might as well have not drawn the lines in the first place.
I often wonder if alot of people think that pictures aren't easily be fudged....and it is easy to do if you don't do them right either by ignorance or other reasons.
As a point (and I could do a better job if this wasn't a superfast attempt) I wanted to show how you can manipulate anything if you want to. This is the equivalent of the original sequence!
Hey Lynn, your head moved forwards....
PS: I do plan to go over the original video at some point and I WILL remove all doubt if any 'deliberate' doctoring that cannot be part of any ignorance is found...I'll do it over next couple of days if can...
