[OM] lighting ratio's of flashes

[Wiliam . Wagenaar0 . 000000E+00DSKSGNETHERLANDS0 . 000000E+00DSNETHERLANDS]

Sorry to all,

In my former mail I was wrong about the lighting ratio's of the different
flashes. Rethinking the theories about flashes I come to the following
conclusion:

Doubling the Flash output rating actually means that the flash has to
quadruple the amount of licht output, because the area it has to lit
quadruples, so the lighting ratio's of flashes fired at the same distances
should be

T20:      20 * 20 =   400     Ratio      1
T32: 32 * 32 = 1024 Ratio     2.56
T45: 45 * 45 = 2025 Ratio     5.06
Assuming all flashes have same angle of illumination.

Have I got it right this time?

Wiliam Wagenaar.
