It was hitting the stumps

Our fielding has held together well, even in the crappest times. But I never fancy us on run outs.
Here we go. The last ten overs. Three hundred looks inevitable, but we need to keep it together.

“Looked” is probably right in this case. The end on camera is quite high up here. this creates a line of sight effect where nearer objects are going to appear to be higher than ones further away. I reckon if this camera is at balcony level, as it seems to be, it’s about 10 m up and 100 m away so simple triangulation tells you that even if he’s right back on the crease at 1.2 m you’ve got a 12 cm line of sight error.

They usually are high up for obvious reasons – if they were at stump height to eliminate any line of sight distortion you wouldn’t be able to see the striker’s end for the umpires arse. But I don’t think people realise quite how distorting that can be.

Although thinking that through I think the effect would be the other way, and would make the point of impact appear lower than it was, so I may be talking nonsense, but it’s too early on a Saturday morning. Either way, the end on camera can’t be trusted on things like height.
