I'm tyring to get an estimate of how far I travelled through the air vertically. Do you think my assumptions and guesses are valid?EXIF data available.

>>209383your logic is still poor. Part of what you're counting isn't even vertical.
>>209390fair enough, I didn't hit it with a lot of speed, so I'd say there's maybe 5 feet of horizontal distance in there. Didn't think it would make that big of a difference since my reference distance is pretty suspect as it is.
>>209378Camera lenses distort the relative sizes of objects, so unless the area you are measuring and the guy are in the same vertical plane the estimate is invalid.
>>209378There are so many variables here that this is a near-random guess.Was the camera perfectly horizontal?Was it taken exactly at the apex of your jump?Are the guy and the front edge of the ridge in the same plane (no)?How much is your lens compressing the perspective?Is the bottom end of your line of measurement at the same altitude as the start of your jump?
>>209411Thanks, I didn't know how valid/invalid my reference length was, and I figured someone in here would know.
