I just purchased a Vivitar DF400MZ flash for my D50 and though it seems to
work fine I can't seem to unscrew the tightening screw to get the flash off
the camera.

I am not totally sure which way the screw should move to undo it (I think
clockwise looking from the top - should have paid more attention when I put
it on). Regardless I can't seem to move it in either direction at least not
by hand.

Any advice on how to loosen the screw so I can remove the flash?

'lefty-loosey / righty-tighty'
:-)
(counter-clockwise to loosen in the vast majority of situations)

Clockwise was the wrong direction. You've probably tightened it so much now
that's the reason for your difficulty.

a) Keep trying, but only counterclockwise

b) Find someone with stronger fingers than you have

c) Find some means of applying leverage, e.g. pliers thin enough to get in
there

As it turns out clockwise is the correct direction for removal (I did
eventually get it off) -- apparently Vivitar flashes (and maybe some
others) are all like this.

Clockwise looking at it from the top, as you described? That's surprising.
I'm pretty sure the locking wheel or nut turned clockwise to lock (i.e., to
tighten against the hot shoe) on every flash unit I've owned that had that
sort of arrangement. But I haven't used such flash units for quite some
time; maybe I'm wrong. Current Nikon flash units have a locking lever
instead.

Well, glad you got it off, anyway, and sorry for the wrong advice.

Neil
