I will try to comment on some other points later but I will pick one
that has been of long time interest to me. Increasing "sharpness" by
reducing focal length or increasing subject distance. Detail is not
increased as magnification is decreased in my opinion. So:
18. If a subject is moving at 100 feet per second appears blurred in
an image made of it at 1/1,000 second (which is the top speed of the
camera) changing to a shorter focal length lens will make the image
detail sharper.
TRUE or FALSE Circle choice and explain:
My "stance" on this is that this is FALSE because the distance that
the subject can move during a given time (the exposure time) is fixed
and thus the ratio of "blur" to subject size remains constant. Blur
(in relation to subject size) is magnification independent. Thoughts
on this?
TX for pointing out watt seconds and joules ...
