There is an amazingly concerted effort behind the Q.
Canon camera chosen
"1600iso" Pennsylvania Ave reference?
"T3" movie about AI that helps the resistance.
3.5/20 second exposure is a reference to the Dog Star, Sirius of Qanis Major. It refers to the 35 days on either side of the conjunction of Sirius in front of the sun.
Here's a video where Trump let's us know that he's a mason. (I don't agree with most of this video) It's just a reference to the number 35.
I think the number 38 is a reference to Saturn as 38 is on the face of the Saturn Square.
For example, a .38 caliber pistol is a Saturday Night Special.
Again. no problem here from me but this helps layout esoteric references.
