Case1: GW detectors and sensitivity

Sensitivity over generations

Why do we care so much about the sensitivity?

Althought ….

But is it the same on everyday tech?

Apologies for flares

There’s no question that I overuse lens flares on occasion … The kneejerk reaction from the director of photography is usually, “OK, we’ve got to flatten that light because it’s going to flare.” I think it’s one of those things that you want to make sure that, obviously, it’s … To me it’s such a cool beautiful image, the light through the glass. There are times that I feel like it sort of adds another kind of smart element, and it’s hard to define. But it is a visual taste that I do like. I think there are a couple shots in Super 8 where I just think I should definitely pull back here or there, but I can’t help myself sometimes.
