Okay so last night I was playing with my camera and a lighted arrow nock, the main purpose was to take a cool picture. But after examining the picture I noticed something interesting.

The arrow flight is what interested me.

first thing I noticed when I zoomed in 100% on the initial flight was a very slight wobble in the beam of light . . . I figured it was either paradox or my flight is not the best . . . since its only near the beginning I am going with paradox.

The second thing I noticed was the flatness of the flight for the first 30 yards and then it seemed to arc down. It is possible that the camera angle had something to do with it??? Here look for yourself . . .

 

So tonight I think I want to try and get two more shots, one over my shoulder, and one from a side view to look at the arc . . .

o and also the distance was 45 yards and the shot impacted right behind the liver, the deer is quartering away approx. 25 degrees

Very cool pic Chris.  What kind of camera are you using?

Very interesting !

That's absolutely amazing. What bow set up are you shooting?

That can't do anything but help your memory re: trajectory!! Cool pic, too.

That's cool.What I can think is that the added weight in the nock end portion can have changed the spine on your arrow.

That is interesting. It will be cool to see the other shots.

Great idea!

Jon, Good to see you over here! "White Falcon"!

chris-very interesting and keep us posted on the rest of your experiment! we are very eager for the results and any other conclusions you come to. thanks.

Very cool,thanks for shar'n.

Very interesting and cool.

Thanks guys,

The camera is a Nikon D5000

The bow in the picture is a 55# deer master take down, launching a 29.5 inch Beeman ICS bowhunter shaft with a 100 grain brass insert and a 100 grain feild tip so about 475 total grains including the feathers and the nock . . .

cacciatore that is possible, I didn't notice a difference in flight with my naked eye . . . but you can see the little squiggle in the beam there in the beginning . . . very good possibility though!!

Can't wait to see the over the shoulder shot!

Alright, so I went out again tonight to do some experimenting.

The first one is just a side view, and unfortunately the nock is starting to die, so it is very light in the picture . . .but you can clearly see that the arrow is really flat for only about 10 yards, and then it starts to arc



This one is good, Cacciatore I think you are right now, in the one photo you can clearly see some cork screw action.


its not the over the shoulder shot I wanted, but it got dark on me, so Im gonna try again tommorrow!!

Keep trying cause these pics are awesome! Helluva practice area you got going too Chris. I'd have a tough time leaving that setup.

The flat flight may be a result of camera lens distortion of depth of field, for starters, and perspective from where the camera was located.

A few years ago The Smithsonian Magazine did a study to understand why a curve ball appears to drop suddenly when viewed from the perspective of the batter. As it turned out the flight of the ball, and its arc,  was constant. It only APPEARS to drop like a rock just before it reaches the batter, thus appearing to him that it will be a hittable. The same thing with an arrow seemingly to fly flat for much of its flight only to drop rapidly later.

Anyway, the arrow is certainly on a constant path and arc. It only appears to fly flat.

Very neat photos BTW!

Very cool!

Ballistics says it can not be flat. I think you are getting a distorted view. Try the camera behind the deer at a slight angle pointing to you
