One of the results of starting in Film,, especially color film,, where the processing was down outside of the house,, is trying to frame the shot in the camera right,, one did not have so many cropping options.
in someways,, the mind/camera got trained to swing/frame/click,, no review afterwards,, you just had to wait and see. There was a bit of the excitement of seeing the first prints out of the envelope.
Here is an example (very early)

The framing was just an instant,, since the train was moving,, and one had to well get it done.
Now,, with digital, I have to make a conscious effort to leave some space,,, my rule of thumb is about 20-25 % extra space for wiggle room,, which allows you to shift the composition,, fix easily slightly tilted frames, etc. a real advantage over the film days,
on the other hand,, being trained to try to get the frame right,, is not all bad either, which having photography students used film for
a semester is a good concept.
