Knowing how everybody likes fire and smoke pics here are some from my shoot a couple of weeks ago.
Sorry it took so long to get these up but it took awhile to figure out how to capture still frames from a iPhone video.
Here's the first shot with a 10 pound ball:
The splash down is right below the red arrow in this one
This is a screen shot from an iPhone app that calculates distance. The green pin on the right is where the mortar was sitting and the red pin on the left is approximately where the ball landed.
This is the second shot with a 16 pound ball.
The ball landed on the small grassy island on the right and the splash doesn't show on the video.
