Technical considerations are definitely important. Sweating the details is what will make the difference between OK and wow. But there is always a time to stop being squeamish and just shoot!
The above is an example.
I saw this scene and barely had time to run and set up the equipment against a not-entirely-clean window. Shooting through windows is not normally a great idea but just look! This was not a scene to miss by obsessing on perfection.
