Circular Flashtube |
Generally, circular flashtubes
are only found on the more expensive line of strobes, but it's
worth the extra cost. Circular flashtubes create the most pleasing
light and, after all, that's the whole purpose of a strobe:
adding light.
Another advantage of circular
flashtubes is that they leave a gap in the middle of the reflector,
and smart manufacturers were quick to use this space to
incorporate modeling (target) lights.
A target light is small flashlight
that pinpoints the strobe's output, helping the photographer to
position the strobe accurately. In general, modeling lights are
somewhat underpowered for shooting in situations where there is a
lot of ambient light; but in darker areas, or especially on night
dives, they are indispensable.
