M(anual) is full-power, MD is "motor drive" (1/16th power, manual),
TTL is "through-the-lens" metering (works on Nikons with the multiple
contacts on the flash shoe). Setting the ASA on the circular scale
(which does nothing electronically to the flash) allows for reading
apertures vs. distances in the different modes. In "M", the "left"
end of the color strip (representing the range in TTL for a particular aperture) indicates the distance (read near the center of the scale, crossed by a radius line) for that aperture (or the other way around).
In "MD", a small notch in the color strip is the marker for reading
the distance (or the other way around). In TTL, use the distance
markers at the hub and the aperture color bands to see if the aperture selected is within the range of the flash maximum power at one end,
and the ability of the flash to cut off the light quickly enough at
the other end of the range. The "W" marker is used when the wide-angle plate is used over the flash head.
The flash may be tilted over a 180 degree range over the top of the camera, and the flash head may be tipped up, down, or sideways, depending on the orientation of the flash relative to the body (the
catch is obscure - flush with the surface at the bottom edge of the
flash head).
I would use a cp05Y filter on this flash when shooting transparencies
- it is a little cold in color, otherwise.
The MD-15 (and 17 for the F3) is a nice medium power flash which
is very compact on the camera, and has movements that are very useful
in macro work, and for getting the flash head away from the usual
on camera location and above the lens in verticals.
Hope This Helps
