Some weeks ago i've talked with one guy who told me that in cameras with tri-linear sensor, the line should be placed some pixels after the first one where we can see the gun flash.
I've tried to search about this, and couldn't find anything that says what he told me (he's a national judge, so that's why i'm trying to find information about that statement. Personally i don't belive that, because while evaluating runners, he doesn't do the same thing, that is, he places the crossair exactly on the athlete).
Does anyone have an opinion about this?
Would really like to see what you guys have to say.
(also, english is not my first language, sorry about mistakes)
